Microsoft 365 Message Center

What and why

We are updating the search experience in SharePoint Online and OneDrive on the web to align with the Copilot Search experience across Microsoft 365. This updated experience allows users to search using natural-language prompts and combines relevant search results, AI-generated summaries with source references, and filters. By bringing SharePoint and OneDrive onto a common search interface, we are providing a more consistent and familiar search experience across Microsoft 365.

Updated November 5, 2026: We have updated the timeline. Thank you for your patience.

Introduction

Microsoft Teams is introducing two new system chat sections called Muted chats and Meeting chats. These sections allow users to organize their chat and channels list by grouping muted conversations and meeting chats into dedicated sections that users can turn on or off. The new Meeting chats section will replace the Meeting chats filter, that was previously available at the top of the chat and channel list.

This message is associated with Microsoft 365 Roadmap ID 559605.

What and why

We are introducing the Join member to channel when user is added to tag template in the Workflows app to automatically add users to selected channels when they are added to a team tag. Once configured, the workflow runs whenever a user is added to the tag, eliminating the need to add members to each channel manually. This is especially useful for location-based or project-based groups where tags correspond to specific sites, regions, or projects, helping new members access relevant channels promptly.

What and why

Microsoft Teams mobile users will be able to decline an incoming Teams call and send a message to the caller at the same time. This gives users a faster way to communicate their availability without answering the call or separately navigating to chat.

From the incoming call screen, users can select Message and choose a predefined response or select Custom to compose a personalized response in the relevant Teams chat.

What and why

We are introducing a new Data access governance report in the SharePoint admin center that allows SharePoint administrators to identify all sites accessible to a given group and the extent of that access. Groups with broad membership, including groups created for vendors, can expose sensitive content to unintended recipients. This report helps administrators investigate potential exposure and verify group permissions.

What and why

Microsoft is updating the authorization model for Exchange Online Admin API v2.0 by introducing dedicated API permissions. This change provides a clearer permission model for applications accessing Exchange Online administrative endpoints and supports the ongoing modernization of Exchange Online administration, including migration from Exchange Web Services (EWS).

The Exchange Online Admin API v2.0 endpoints are not being retired. Only the permissions used to access them are changing:

• Exchange.ManageV2 is being replaced by Exchange.AdminAPI.Manage.
• Exchange.ManageAsAppV2 is being replaced by Exchange.AdminAPI.ManageAsApp.

Applications using the affected permissions must transition to the corresponding new permissions to maintain uninterrupted access.

What and why

Microsoft is updating the Exchange Online Admin API v2.0 MailboxFolderPermission endpoint to return the User property as a structured object instead of a display-name string. The new response includes DisplayName, Name, and PrimarySmtpAddress, helping applications more reliably identify users with similar or identical display names and supporting mailbox folder permission management and EWS migration scenarios.

What and why

The Planner Plugin connects Microsoft Planner to Copilot Cowork, helping users understand their priorities, get help completing tasks, and keep their plans current. Cowork can use Planner task notes, checklists, and attachments to research, draft, analyze, and create deliverables. It can also turn existing content into plans, generate visual status reports, and use Planner context for work across Microsoft 365. Users review and approve changes before Cowork updates Planner.

• Deny Recording Download
• Deny Transcription Download

• The user can continue to view and play back recordings and transcripts as permitted by existing access.
• The user is blocked from downloading the corresponding artifact.

Updated November 5, 2026: We have updated the timeline. Thank you for your patience.

What and why

We are introducing Move to Quarantine, a new remediation action in Microsoft Defender for Office 365. It enables security teams to move potentially malicious email messages from users' mailboxes directly to Microsoft Defender quarantine. This provides a safer and more flexible way to contain suspicious messages that bypassed initial detection while preserving the ability to investigate, release, or permanently delete them later.

This capability is available with Microsoft Defender for Office 365 Plan 2, including eligible Microsoft 365 subscriptions that include Plan 2.

Updated November 5, 2026: We have updated this post as a reminder. Thank you for your patience.

What and why

File policies in Microsoft Defender for Cloud Apps are being retired on January 6th 2027. After this date, data loss prevention (DLP) file policies configured in Defender will no longer be supported or enforced.

Equivalent file policy capabilities for SharePoint and OneDrive previously supported by Microsoft Defender for Cloud Apps are now generally available in Microsoft Purview. No cost options are available for customers without the required Purview licenses. This will enable a unified experience in Purview for securing enterprise data, where there will be continued investment in discovering, classifying, and protecting sensitive data across the organization.

Updated November 5, 2026: We have updated the timeline. Thank you for your patience.

What and why

Now users have the full power of Office in Microsoft Copilot app, so users can create, edit and collaborate on Word, Excel and PowerPoint files, without leaving the app.

What and why

We are improving the shared message experience in Microsoft Viva Engage to make it easier for users to discover, read, and participate in conversations shared by their colleagues. Shared messages will display richer previews of the original post, including formatted text, images, videos, and attachments. On Viva Engage web surfaces, users will be able to open and interact with the full conversation without losing their place in the feed.

What and why

We are expanding Planner Agent in Microsoft Copilot Chat with task assignment, scheduled task catch-up, and Copilot memory integration. These improvements help users manage tasks and shared plans, identify outstanding work, and receive personalized responses. We are also improving support for larger plans, response quality, speed, and reliability.

What and why

We are retiring the Project usage report (Project activity) from Reports > Usage in the Microsoft 365 admin center. Currently, the report shows how many users are active in the Project desktop client, Project Online, and Project for the web. Because Project Online and Project for the web have been retired, the Project usage report is also being retired. Starting December 4, 2026, the Project usage report will no longer be available in the Microsoft 365 admin center, and its historical data will no longer be accessible there.

What and why

Users can now select a mail folder and scope Outlook search results to that folder. This update gives users more control over their searches by helping them narrow results to a specific folder.

What and why

Copilot connectors will extend Work IQ beyond Microsoft 365 by making data and tools from connected enterprise systems available to AI agents through Work IQ APIs. Organizations can use their existing Copilot connector investments to build richer, more context-aware agentic experiences across Microsoft 365 and enterprise systems without requiring separate connector setup or management.

Existing administrator controls, permissions, and governance policies for Copilot connectors will continue to apply.

• Dynamic priority escalation: Adjust priority based on wait time, queue transfers, customer tier, and other conditions.
• Overflow handling: Trigger callbacks, route conversations to alternate queues, expand assignment eligibility, notify supervisors, or send contextual customer messages when defined conditions occur, including for direct inward dial calls.
• Preferred representative assignment: Reconnect customers with previously engaged or preferred representatives when available and within capacity, with fallback to another qualified representative.
• Bullseye routing: Expand the pool of eligible representatives over time based on skills, proficiency, teams, or other criteria.

What and why

Microsoft Purview eDiscovery is introducing three read-only diagnostic checks for case access, security filters, and hold-policy distribution. These checks help admins understand and troubleshoot common access, search-scoping, and hold-distribution issues directly in the product.

This message is associated with Microsoft 365 Roadmap ID 565222

Updated November 2, 2026: We have decided not to move forward with this change at this time. We apologize for any inconvenience.

Introduction

We’re enhancing Microsoft Purview Content Explorer with new summary metrics to improve visibility into scanning and classification activities. These updates will help admins identify unscanned files and monitor classification trends, enabling better data governance and informed decisions.

This message is associated with Roadmap ID 526796.

We've released updates to the following update channel for Microsoft 365 Apps:

• Current Channel

Updated November 4, 2026: We have updated the timeline. Thank you for your patience.

Introduction

We’re adding support for sending locally stored Word, Excel, and PowerPoint files as email attachments directly through the new Outlook for Windows. This update streamlines the sharing experience and aligns with ongoing efforts to bring feature parity between classic Outlook for Windows and the new Outlook.

This message is associated with Microsoft 365 Roadmap ID 557675.

Updated November 3, 2026: We’ve heard your feedback that you’d like more information about what’s changing in classic Outlook. To help end-users understand recent changes, we’re bringing back the What’s New in-app dialog.

The dialog is designed to be nonintrusive and will appear automatically at most once per month in Production on Current Channel. Users can dismiss it at any time and reopen it later by selecting the What’s New button on the ribbon. Administrators can turn off the automated dialog and hide its ribbon button.

For more information and configuration instructions, see What’s New in classic Outlook for Windows.

What and why

We’re making updates across Microsoft Outlook experiences to improve clarity and consistency across endpoints. The first updates focus on visual details such as icons, spacing, and alignment, while maintaining familiar ways of working.

These updates are part of an ongoing series of improvements across Outlook experiences and are not a replacement for the classic Outlook experience.

What and why

We are refreshing the Analytics & Reports experience in the Microsoft Teams Rooms Pro Management portal with an updated design and simplified navigation. New Room analytics and Desk analytics navigation options will make it easier for admins to access workplace data and insights to help optimize spaces, improve operations, and make informed decisions.

What and why

Microsoft is bringing featured playlists from AI Skills Navigator into Learning Agent in Microsoft 365 Copilot. Featured playlists bring related learning resources together around a role, product, or skill. Users can discover these structured collections through natural language conversations in Learning Agent, helping them spend less time searching individual learning resources and more time building practical AI skills.

Users can discover featured playlists with prompts such as:

• What playlists can help me build AI skills for sales?
• Find a playlist that helps me create better marketing campaigns with AI.
• Recommend some playlists to help me do code reviews faster using AI.
• Find me some playlists that help me manage my company's AI costs better.
• Show me some playlists on how I can get more done at work using agents.

What and why

Microsoft Defender role-based access control (Defender RBAC), the unified permissions model for Defender, is becoming the single access model for all Defender and Sentinel portal experiences. This will happen in a phased roll-out.

First, your existing roles will be imported into the new RBAC model, giving you time to review and adjust them during the notification period. Following this period, the new Defender RBAC will be activated automatically for the in-scope workload(s), approximately 30 days after the in-portal notification date.

The new Defender RBAC offers more extended access management capabilities, including:

• A single access management system to manage all roles and permissions across all workloads.
• Scoping capabilities across device groups, cloud, identity, and Sentinel.
• Future-proof assignments that will allow you to include future permissions and workloads.
• A prerequisite for newly introduced offerings, such as Perception.

This change applies to Microsoft Defender and Microsoft Sentinel. Permissions for Microsoft Purview, Exchange Online, Microsoft Entra directory roles, Privileged Identity Management, and Azure resources (not related to Microsoft Sentinel) remain unchanged. In addition, if you are using PowerShell with Microsoft Defender for Office 365, this will continue to work as is.

Workloads: The portal will identify which workloads will be enabled automatically and their activation dates.

How you will be notified:

• Notification banner: A notification will be displayed in the Microsoft Defender portal informing customers that the specified workload(s) will transition to the new RBAC model. Legacy roles are automatically imported. The notification banner and role import mark the beginning of the customer notification period before automatic activation.
• Activation date: Beginning approximately 30 days after the notification date, the new Defender RBAC will be enabled automatically for the specified workload(s). Customers can review imported role assignments and prepare for the transition during this period.
• The in-portal banner in the Microsoft Defender portal (‘Permissions and roles’ page) will confirm activation.

What and why

Intelligent call delegation is moving from Frontier public preview to public preview (Ring 3.6) beginning as early as November 17, 2026. This capability uses AI to screen incoming calls, gather context, and help users decide when to engage. It can also schedule follow-up appointments via Microsoft Bookings.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft is updating how private tasks are stored in Microsoft Planner. Beginning in December 2026, private tasks created in Planner and Planner-powered experiences will be stored in a user's own private Planner plan instead of the Microsoft To Do task store.

This enables richer Planner capabilities, such as labels and task history, while maintaining the same private experience. Private tasks remain visible only to the task owner and cannot be shared or assigned to others. This change aligns private task management with the Planner platform while preserving enterprise compliance and security protections.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft is introducing a redesigned My Tasks experience in Planner to help users more easily identify, prioritize, and manage their work. The updated experience provides clearer navigation, improved task organization, and streamlined task creation workflows, enabling users to create and manage tasks more efficiently without leaving their current context. This supports improved personal productivity by helping users focus on the work that requires their attention and reducing friction in everyday task management.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Teams is updating how administrators and meeting organizers configure AI for Teams meetings. The existing Copilot meeting policy is being replaced by two more specific policies:

• MeetingAI - controls whether Copilot, Facilitator, Intelligent Recap, and other AI features are available in meetings.
• TranscriptionWithMeetingAI - controls whether transcription starts automatically when meeting AI is turned on.

This gives administrators clearer, more predictable control over whether AI is available and whether it requires (or works without) transcription, including the ability to enforce Copilot off. Organizers also gain more visibility into, and in some cases control over, these settings directly from the meeting options.

Meeting options are also being updated to make AI controls easier to understand and to provide more granular control over who can enable, manage, and use AI capabilities, including a new who can manage option that replaces the existing Allow Copilot and Facilitator meeting option:

• Who can manage AI - replaces the existing Allow Copilot and Facilitator option and determines who can turn Copilot and other AI features on or off during a meeting. If an admin turns Meeting AI off, this option is set to No one.
• Who can use AI - provides more granular control over which meeting participants can use Copilot and other AI capabilities.
• Start Transcription with AI - lets organizers choose whether transcription starts with AI. Administrators can also control this option through Teams admin center.
• Intelligent Recap controls - lets organizers decide whether an Intelligent Recap is created when Copilot is turned on, including for meetings where a transcript is not created.

What and why

Microsoft Teams is expanding the Invite to register experience for Teams events with registration enabled. Organizers can select people to receive an email invitation with a link to register for the event.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Purview Information Protection is enhancing auto-labeling policy management to help administrators deploy, validate, and monitor labeling policies across larger data estates. These updates increase policy scale limits, improve SharePoint targeting capabilities, and provide enhanced reporting and auditing insights to help organizations better understand policy effectiveness and processing activity.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Teams is introducing additional protection for QR codes shared by external users in Teams messages. To help reduce the risk of phishing and fraud, images containing QR codes from external senders will be obscured by default. Users can choose to reveal the image before viewing or scanning the QR code.

This security enhancement promotes safer interactions with content received from external users while maintaining flexibility for trusted communications.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

We're updating the Microsoft Teams mobile experience with a redesigned header and lightweight dashboard for chats and channels. This update brings key channel details, people, and pinned content into a single, intuitive experience, helping users find information and take action more quickly.

The updated experience creates a more consistent navigation model across desktop and mobile, making it easier for users to move between chats and channels.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Teams is introducing a new meeting protection policy that allows administrators to automatically block identified external meeting bots from joining Teams meetings.

Today, Teams can identify meeting bots and provide visibility to organizers and administrators. With this update, organizations can strengthen meeting security by configuring Teams policies to automatically block detected external meeting bots from joining meetings. This gives administrators additional control over how identified bots are handled and can help reduce organizational risk.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Teams is expanding presenter visibility in Manage what attendees see for Teams events. Event organizers and producers can now drag and resize the presenter panel, allowing them to view more presenters simultaneously during event production.

This improvement helps producers more easily monitor available presenters, streamline presenter transitions, and manage large events with greater efficiency.

This message is associated with Microsoft 365 Roadmap ID 567467.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

We are introducing centralized notification settings for channels in Microsoft Teams. Users will have a single location to view and manage notification preferences across their channels instead of configuring settings individually for each channel. This simplifies notification management and reduces the effort required to review and update settings.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

Users are currently blocked from sending messages in Microsoft Teams while a file upload is in progress, which can disrupt real-time collaboration. With this update, file uploads will occur asynchronously in the background, allowing users to continue sending messages without interruption.

This message is associated with Microsoft 365 Roadmap ID 560813.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

Introduction

Microsoft Teams is expanding breakout room capacity to support larger meetings. With this update, breakout rooms can be used in meetings with up to 1,000 attendees, allowing organizers to run large meetings while still enabling smaller group collaboration. This change removes the need to limit meeting size in order to use breakout rooms.

This message is associated with Microsoft 365 Roadmap ID 560320.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

Introduction

Microsoft Teams town halls and live events will soon support Secure Reliable Transport (SRT), a secure and resilient video streaming protocol designed to deliver high‑quality, low‑latency video over the public internet. SRT will be available alongside Real‑Time Messaging Protocol (RTMP), the existing inbound streaming protocol commonly used with external encoders. Adding SRT provides event organizers with improved reliability and flexibility, including support for backup streams with automatic failover, to help ensure smoother delivery for high‑visibility broadcast events without increasing setup complexity.

This message applies to Teams for Windows desktop and Teams for Mac desktop and is associated with Roadmap ID 554931.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

Introduction

We are improving the Microsoft Teams meeting experience when the active meeting window is minimized. This update helps users stay engaged in meetings while multitasking across other apps. With this change, users can perform key in-meeting actions—such as raising their hand and sending reactions—without restoring the full Teams meeting window. Users can also choose between two different minimized views, depending on how much meeting context they want to keep visible while they work.

This change does not affect the experience when users are sharing their screen in a Teams meeting.

This message applies to Teams for Windows desktop and Teams for Mac desktop. It is associated with Microsoft 365 Roadmap ID 557179.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

A new streaming switchboard in Microsoft Teams will allow event producers to more easily manage and send NDI® sources to production software during Teams meetings and events. Event producers can individually select and stream up to eight NDI sources directly from a Teams meeting or event.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

Two presenters can share a screen or window at the same time in a Teams meeting. Participants can see both shared content streams simultaneously, making it easier to compare and discuss content from different presenters. This message is associated with Microsoft 365 Roadmap ID 80239.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Teams will enable users to report guest invitations for security concerns directly from Teams. When users receive an unexpected or potentially malicious invitation to join another organization as a guest, they can report it to their IT admin for review, helping identify and mitigate phishing and other abuse through guest invitations.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Teams is introducing an onboarding workflow that helps new team members get started faster by automatically connecting them to relevant channels when they join a team. This can improve engagement, accelerate onboarding, and make important information easier to find from the start.

We are introducing a new Copilot skill in PowerPoint, Prepare internal sales review, that helps users create senior-leadership presentations summarizing sales performance, outlook, risks, and decisions.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

We are introducing a new Copilot skill in PowerPoint, Review sales pipeline, that helps users create or refresh internal pipeline and forecast review presentations focused on opportunity movement, risks, and next actions.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

We are introducing a new Copilot skill in PowerPoint, Draft proposal response, that helps users create customer-specific proposal or bid presentation drafts in response to explicit requirements or RFPs.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

We are introducing a new Copilot skill in PowerPoint, Prepare customer review deck, that helps users create recurring customer-facing business review (QBR) presentations focused on goals, outcomes, adoption, risks, commitments, and next steps.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

We’re updating the thumbs-down feedback experience in Microsoft Copilot to make it easier for users to provide specific, actionable feedback. Today, many thumbs-down responses are submitted without comments, providing sentiment but limited information about the issue. When users select thumbs down, they’ll be able to select one or more feedback categories and optionally provide additional comments, giving each categorized response a signal that can be routed to the appropriate team or issue type.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

We are introducing a new policy that separates Teams Events attendance and engagement report controls from Teams Meetings attendance and engagement report controls. With this change, administrators can independently manage organizer access to attendance and engagement reports for Teams Events through CsTeamsEventsPolicy, without affecting attendance and engagement report settings for Teams Meetings managed through CsTeamsMeetingPolicy.

This update provides greater administrative flexibility by allowing separate configuration of attendance and engagement reporting for Teams Events and Teams Meetings.

Updated November 3, 2026: We have updated the timeline. Thank you for your patience.

What and why

We are introducing a new Copilot skill in PowerPoint that helps users create customer-facing sales pitch presentations. Users can use this skill for scenarios such as a first customer meeting, warm-lead product introduction, industry-specific pitch, or internal sales enablement. The skill helps users shape a commercial story around the audience, opportunity, key messages, supporting evidence, and recommended next step.

Microsoft uses fair use limits for some Copilot features for users without a Microsoft 365 Copilot license.

Features, such as image generation, already use limits, as previously communicated in MC1064749. We are applying this approach to additional Copilot Chat features and capabilities.

Users will be notified in-product if the capacity or feature is not available.

What and why

Conversation orchestration in Microsoft Dynamics 365 Contact center actively manages conversations throughout their lifecycle, from initiation through resolution. As conditions change, such as increasing wait times, queues filling quickly, or representatives going offline, conversation orchestration can automatically take actions defined in natural-language playbooks configured by administrators.

Administrators can configure playbooks for specific scenarios using guided templates. Built-in validation identifies conflicts before playbooks are published. These capabilities help organizations automate contact center processes while improving routing, continuity, and responsiveness.

What and why

We are adding a new What's happening across your organization section beneath community and storyline notifications in the Microsoft Teams Activity feed. The section helps users discover relevant content beyond their immediate communities, including posts from leaders and official communities, and provides ways to join communities or follow colleagues directly from the notification experience.

What and why

We heard your feedback that the 100-user exception limit was too small to support meaningful pilot and validation audiences, particularly in larger organizations. We previously introduced Microsoft Entra ID group support to simplify audience management. We are now increasing the exception limit from 100 to 10,000 users per tenant, giving administrators more flexibility to manage release readiness at scale.

This update lets you assign a larger audience to a release preference different from your tenant-wide selection - for example, keeping a larger validation group on Standard release while the rest of your organization uses Deferred release.

What and why

Facilitator can help users identify suspected social-engineering attempts by people outside their organization during a meeting. When Facilitator is present, its Protection skill uses AI to check the meeting transcript for signs that someone may be attempting to trick users into sharing sensitive information. If a suspected attempt is detected, users will see a warning with options to end the meeting or temporarily restrict information sharing.

This feature can help organizations reduce the risk of sensitive information being disclosed through social engineering during meetings with external participants.

What and why

New accounting capabilities in Copilot in Excel and Cowork help finance professionals complete common accounting tasks in the tools they already use. Users can reconcile accounts, prepare journal entries, analyze financial performance and variances, and prepare financial reports. Additional capabilities support budgeting, forecasting, audit, tax, compliance, and training.

Copilot prepares the work while users retain control of review, approval, and posting. Nothing is posted automatically to an ERP or system of record without approval.

What and why

As Microsoft-provided SMS and voice authentication retire in Microsoft Entra ID, these methods will also become unavailable for SSPR. Organizations have 50 days after the applicable sign-in retirement rollout reaches their tenant to prepare alternative recovery methods. Users may still be able to sign in but lose the ability to reset forgotten passwords. Passkeys and other sign-in methods don't automatically satisfy SSPR requirements. Admins should identify affected users and ensure they have enough eligible recovery methods to prevent disruptions and increased helpdesk requests.

What and why

We’re expanding Unified role-based access control (URBAC) permission support for Email & collaboration content: Emails associated with alerts in Microsoft Defender. This change provides more consistent email content access across alert investigation scenarios based on a user’s assigned permissions.

Previously, this permission applied to:

• Email reported by user as malware or phish
• Email reported by user as junk

With this rollout, the permission will also apply to:

• A potentially malicious URL click was detected
• A user clicked through to a potentially malicious URL

Updated November 2, 2026: We have updated the timeline. Thank you for your patience.

What and why

Copilot Notebooks now lets users add Power BI reports as references, bringing report data directly into their notebooks alongside files. Copilot uses this information to help generate more relevant summaries, presentations, and briefs grounded in the organization's data.

Updated November 2, 2026: We have updated the timeline. Thank you for your patience.

We’re introducing My Team audiences and expanded targeting capabilities in Viva Engage to help leaders communicate with the employees in their organization and tailor messages to relevant teams, departments, locations, or groups. My Team provides a ready-to-use, automatically maintained audience based on the organizational hierarchy, so leaders can reach the employees who report up to them, including both direct and indirect reports. This audience helps unlock and improve leadership experiences across Viva Engage, making Storyline Announcements, audience analytics, Leadership Corner, and feed and digest distribution more relevant with less setup.

Leaders and delegates can use My Team as-is, review its membership, or further customize and save it as a reusable audience across leader communication experiences. For Storyline Announcements, they can also define recipients at the time of publish, choosing My Team, a saved audience, or a custom audience built using organizational attributes such as department, job title, or country; existing groups like M365 Groups, distribution lists, or security groups; and individual users by name. Together, My Team and flexible targeting make leader communications more relevant, scalable, and easier to manage - with a dynamic default audience and precise targeting for relevant employee groups.

What and why

We're introducing breakout room support for Microsoft Teams Rooms on Android. This update allows Teams Rooms on Android devices to be assigned to breakout rooms and moved between breakout rooms and the main meeting room by meeting organizers.

This feature improves coordination during breakout sessions and brings Microsoft Teams Rooms on Android closer to feature parity with Microsoft Teams Rooms on Windows. This enhancement is based on customer feedback and helps organizations deliver a more consistent meeting experience across Teams Rooms devices.

Updated November 2, 2026: We have updated the timeline. Thank you for your patience.

What and why

We are updating how users access document summarization in Microsoft Word. Beginning in September 2026, the current Top of Doc summarization experience will transition to other Copilot in Word surfaces.

This change creates a more unified Copilot experience in Word while preserving users’ ability to quickly understand document content. The document summarization capability is not being removed and will continue to be available through Copilot in Word.

Updated November 2, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Teams is expanding admin controls for Weaponizable File Protection. Admins will be able to customize which file extensions are blocked in Teams based on their organization’s security needs or continue using the Microsoft-recommended default list. This change provides greater flexibility to tailor file protection policies while maintaining a secure collaboration experience.

• Copilot (AI-powered assistant) will no longer suggest names for similar controls or offer to apply multiple suggested renames when a supported control is manually renamed.
• This change is enforced and cannot be opted out. Existing app control names and formulas will not be affected.

Updated October 30, 2026: We have updated the timeline. Thank you for your patience.

Introduction

Microsoft Entra passkeys on Windows will soon be Generally Available, enabling phishing‑resistant, passwordless sign‑in to Microsoft Entra‑protected resources from Windows devices.

The Public Preview of this capability was previously announced in MC1247893.

Users can create device‑bound passkeys stored in the Windows Hello container and authenticate using Windows Hello methods (face, fingerprint, or PIN). This expands passwordless authentication support to Windows devices that aren’t Microsoft Entra‑joined or registered, helping organizations strengthen security and reduce reliance on passwords across corporate‑managed, personal, and shared device scenarios.

Updated October 30, 2026: We have updated the timeline. Thank you for your patience.

Starting in March 2026, Microsoft Entra ID will introduce passkey profiles and synced passkeys to General Availability (GA). This update allows administrators to opt in to a new passkey profiles experience that supports group-based passkey configurations and introduces a new passkeyType property.

Important: Only tenants that already have Passkeys (FIDO2) enabled are affected by this update.

The passkeyType property enables admins to configure:

• Device-bound passkeys
• Synced passkeys
• Both

If your tenant already has Passkeys (FIDO2) enabled and you do not opt in to passkey profiles during the initial rollout window, your tenant will be automatically migrated to the passkey profiles schema at the date range specified below. When this occurs:

• Existing Passkey (FIDO2) authentication method configurations will be moved into a Default passkey profile.
• The passkeyType value will be set based on the tenant’s current attestation settings. Synced passkeys will be enabled for tenants with attestation enforcement disabled.
• No new authentication methods are enabled as part of this migration.
• This migration also impacts Authentication methods registration campaign set to “Microsoft managed” state, which uses passkey configuration settings to determine which registration prompts are shown to users.

Authentication Methods Registration Campaign changes (Microsoft-Managed Only)

Tenants are impacted when all the following conditions are met:

• The Passkeys (FIDO2) authentication method policy is Enabled
• Authentication methods registration campaign is set to “Microsoft managed” state
• Allow self-service setup is Enabled
• Target specific AAGUIDs is not selected (no AAGUID restrictions configured)
• The Authentication Methods Registration Campaign state is set to Microsoft-managed
• The tenant has at least one user enabled for both synced passkeys and device‑bound passkeys
  • Only users who are enabled for both synced passkeys and device‑bound passkeys, with no passkey profile restrictions configured (i.e. attestation enforcement, AAGUID restrictions), will receive a passkey registration nudge during sign‑in.

For these tenants, Microsoft-managed registration campaign settings will be updated after passkey profile automatic migration is complete. We will roll out changes incrementally to in-scope tenants according to the timeline outlined below.

What and why

Granular Conditional Access for Teams meetings enables organizations to apply more targeted access controls to help protect sensitive meetings. Administrators can use Conditional Access policies to enforce specific access requirements for selected meetings, helping ensure that participants meet organizational security requirements before joining.

What and why

Stay up-to-date with what's happening in your other accounts and organizations with the 'Activity in Other Accounts and Orgs' panel. Preview and open chats, channels, and other activity in other accounts and orgs from your main Teams window - no tenant switching required.

What and why

Get a closer look at shared content in Teams calls and meetings with pinch-to-zoom using your touchpad. Quickly zoom in to make small text and detailed visuals easier to see, then zoom back out for the full view. Existing zoom controls remain available.

What and why

When investigating a suspicious Microsoft Teams call or meeting, your security team needs to understand what happened, who initiated the activity, and the organization associated with the initiator.

The CallActivityEvents table in Microsoft Defender XDR advanced hunting provides visibility into activities performed during Teams calls and meetings in your organization. Security teams can use this information to investigate suspicious activity, review related messages, and correlate findings with other security signals.

This capability is available to organizations with Microsoft Defender for Office 365 Plan 2.

Updated October 30, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Purview is expanding Data Loss Prevention (DLP) and Information Protection auto-labeling support for non-Microsoft applications. Administrators will be able to create and manage DLP and auto-labeling policies directly in Microsoft Purview for supported non-Microsoft applications.

These capabilities use Microsoft Defender for Cloud Apps connectors to connect supported non-Microsoft applications to Microsoft Purview.

Introduction

Microsoft Edge for Business will soon support summarization and contextual grounding with Microsoft 365 Copilot Chat. This enhancement enables users to ask Copilot questions about multiple open browser tabs, and YouTube videos directly from the Edge side pane.

This message is associated with Microsoft 365 Roadmap ID 496364, 499423, and 499424.

Updated October 30, 2026: We have updated this post with additional information as the feature is now generally available. Thank you for your patience.

What and why

Choose Your Own Telephony Provider (CYOT) is now generally available in Microsoft Entra ID. With CYOT, your organization can deliver SMS and voice authentication through a supported telecom provider of its choice. You purchase the provider's offer in Microsoft Security Store and manage the commercial relationship directly with the provider.

Microsoft-provided SMS and voice authentication begins retiring on February 1, 2027. To keep SMS and voice authentication available for users who need it, set up CYOT before that date.

Microsoft recommends phishing-resistant authentication methods, such as passkeys, instead of SMS or voice. Use telephony-based authentication only for users who have a business, regulatory, or technical need for it.

What you need to do

If your organization plans to use CYOT:

1. Identify users who need SMS or voice. Confirm which users have a requirement that phishing-resistant methods can't meet.
2. Choose a provider. Compare the supported telecom providers on coverage, channels, pricing, support, and compliance.
3. Check purchasing requirements. Confirm that you have a paid Azure subscription that is eligible for Security Store purchases, and that you have the Owner role, or Contributor plus Role Based Access Control Administrator.
4. Estimate costs. Review provider pricing and Azure hosting costs.
5. Set up and roll out. Follow Set up SMS and voice. Start in evaluation mode, then increase traffic to your provider in stages.
6. Complete your transition before February 1, 2027. Review the guidance for the retirement of Microsoft-provided SMS and voice authentication.

What and why

Microsoft Teams is introducing AI generated meeting memory files that capture key insights from meetings (formerly archive files). These files help Microsoft 365 Copilot and Facilitator deliver more accurate context aware responses while maintaining strong privacy controls by not storing raw meeting content. This capability supports enterprise ready AI by improving knowledge grounding while keeping data secure and manageable.

This message is associated with Microsoft 365 Roadmap ID 558933.

Updated October 30, 2026: We have updated the timeline. Thank you for your patience.

What and why

Beginning mid-March 2027, Microsoft will start retiring the Microsoft Purview Data Security Posture Management (DSPM) classic and DSPM for AI classic experiences. Retirement will be completed by end of March 2027.

As part of our continued investment in Microsoft Purview Data Security Posture Management, we have unified DSPM capabilities into a single experience that helps organizations discover, protect, and investigate data risks across traditional data sources and AI applications and agents.

Updated October 30, 2026: Gov rollout of this feature is paused at this time. We will communicate via Message center when we are ready to proceed. We apologize for any inconvenience.

What and why

Exchange Web Services (EWS) deprecation begins October 1, 2026. Cross-tenant collaboration features — Free/Busy, MailTips, and Calendar Sharing — currently rely on EWS.

Cross-tenant Free/Busy, MailTips will be available by September 2026 and Calendar Sharing will be available by early November 2026 (previously end-October) via Microsoft 365 Cross-Tenant Access Policy, which replaces EWS-based cross-tenant collaboration.

What and why

We're updating the default message layout for new Microsoft Teams channels created through the Microsoft Graph v1.0 Create channel API (POST /v1.0/teams/{team-id}/channels). When a channel creation request doesn't specify the layoutType property, the new channel will use the Threads layout instead of the Posts layout.

This change applies only to newly created channels. Existing channels won't change.

Updated October 29, 2026: We have updated the timeline. Thank you for your patience.

Introduction

We’re introducing a simpler way to view conversations in Viva Engage communities, organized by recent posts rather than recent activity. This new view is designed to make it easier for users to follow discussions and will be available as an option, alongside the current system, for those who prefer sorting by recent activity and filtering to new conversations only.

This message is associated with Microsoft 365 Roadmap ID 513275.

What and why

We’re introducing Draft Mode for official Brand Kits. Draft Mode gives Brand Managers a workspace to make and review changes before publishing them. Changes remain in draft and do not affect the current live Brand Kit until the updated kit is published.

What and why

Microsoft Teams will support explicit consent for participants connected through the public switched telephone network (PSTN) in one-to-one Teams calls. When explicit consent is required, PSTN participants will hear an audio prompt when recording or transcription starts and can use their phone keypad to consent or decline. Participants who decline can remain in the call but stay muted. This capability extends the existing Teams calling policy for explicit consent to one-to-one PSTN calls.

What and why

Microsoft Purview service-side auto-labeling is adding support for legacy Microsoft Office file formats, including Word (.doc), Excel (.xls), and PowerPoint (.ppt). Organizations can automatically evaluate and apply sensitivity labels to these files in SharePoint and OneDrive. These legacy file formats will be supported in both simulation and enforcement.

Updated October 29, 2026: We have updated the timeline. Thank you for your patience.

What and why

We’re updating Microsoft Authenticator with several usability improvements across iOS and Android. These updates include a refreshed home experience, clearer guidance for accounts that need to be restored, improvements to restoration and sign-in flows, and additional prompts designed to help keep Authenticator working reliably. Availability and timing vary by platform.

Updated October 29, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Teams will enable meeting participants to start and continue one-to-one or small-group conversations directly from the meeting chat experience. Users can create a side conversation without leaving the meeting context, helping them coordinate, ask questions, share information, and collaborate in parallel while keeping the main meeting discussion focused.

Updated October 28, 2026: We have updated the timeline. Thank you for your patience.

Introduction

As part of our ongoing mission to deliver a modern, secure, and scalable one-stop management portal for admins, we are transitioning Teams Android device management from the Teams admin center (TAC) to the Teams Rooms Pro Management portal (PMP).

This move consolidates management of all Teams devices, including Teams Rooms on Windows, Teams Rooms on Android, Teams phones, and Teams panels, into a single unified portal, providing IT admins a consistent and seamless experience for managing devices at scale.

This message is associated with Roadmap ID 555235.

What and why

Impersonation protection for Teams meetings helps users identify potentially deceptive participants and meeting organizers. When Teams detects a potential impersonation attempt, it surfaces warnings and risk indicators to help users recognize suspicious identities and make more informed decisions when joining or participating in a meeting.

Updated October 28, 2026: We have updated the timeline. Thank you for your patience.

What and why

The All Accounts view, also known as Unified Inbox, lets users see email from multiple connected accounts in a single inbox view in the new Outlook for Windows without merging their mailboxes. Each account's inbox stays separate, and All Accounts view brings messages together so users can triage mail from one place.

Users can read, delete, search, move, archive, and mark messages across accounts without switching between mailboxes. The experience integrates with Copilot for AI-assisted email workflows and supports Search with Copilot for finding messages across the user's primary account.

What and why

Microsoft is introducing a refreshed user experience for SharePoint Lists to make common actions easier to find, improve navigation, and provide greater visibility into views and active filters. The refreshed experience includes a reorganized command bar, clearer breadcrumb navigation for lists that use folders, more prominent view selection and creation, visible filter pills, and consolidated view customization options. These updates are intended to make everyday list tasks more intuitive and help users better understand and manage the information displayed in their views.

What and why

We are introducing the Engage plugin for Copilot Cowork and Autopilot, with general availability targeted for November 16, 2026.

The plugin brings Engage conversations and actions into Copilot workflows. Users can catch up on community discussions, find relevant information, understand employee questions and feedback, and draft or publish updates without switching to Engage.

• PowerPlatformInfra
• PowerPlatformPlex

• Europe: November 2, 2026
• United States: November 9, 2026

• HTTP action
• HTTP + Swagger action
• HTTP Webhook action
• HTTP Webhook trigger (the requests that Power Automate sends to your service to subscribe and unsubscribe)

1. Find the services that your flows call with these actions and triggers, and check which of them accept traffic only from approved IP addresses. Include firewalls, gateways and web application firewalls in front of those services.
2. Allow incoming traffic from the LogicApps, PowerPlatformInfra and PowerPlatformPlex service tags:
   • For Azure resources that accept a service tag as the source of an inbound rule, such as network security groups and App Service access restrictions, add the three service tags to those rules.
   • For other firewalls, including Azure Firewall, add the IP address ranges of these service tags from the Azure IP Ranges and Service Tags file or the Service Tag Discovery API. The ranges change over time, so keep them up to date.
3. After you update an allow list, confirm that the flows that call that service still succeed.

What and why

We are adding support for external presenters in event group chat, the private chat used by organizers, co-organizers, and presenters for coordination during an event or structured meeting. This change enables presenters who are outside the tenant hosting the meeting or event to participate in the event group chat.

Updated October 26, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Entra ID is adding safeguards to reduce automated abuse of telephony-based authentication. SMS and voice authentication options are not being removed. Some users who use SMS or voice for first-factor sign-in may be asked to complete a risk-based anti-bot verification step (CAPTCHA) before a code is sent.

We've released updates to the following update channel for Microsoft 365 Apps:

• Current Channel

Updated October 28, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Defender for Office 365 is introducing new email submissions data in Advanced Hunting in Microsoft Defender. The new submissions tables provide security operations teams with greater visibility into email submission activity and results, enabling analysts to query submission activity alongside other Defender data and build hunting and detection workflows tailored to their organization.

What and why

Frontier now covers more of Microsoft 365. Starting in November 2026, users enrolled in Frontier will start getting eligible public preview features in Microsoft Teams, new Outlook for Windows, OneDrive, and SharePoint, in addition to Copilot.

Instead of looking in different places for previews, admins use one program and one setting to give the users they choose early access across Microsoft 365.

Frontier is optional and controlled by your admins. It is separate from each user's Standard release or Deferred release preference, which still decides when users receive features once they're generally available. If you already have users enrolled in Frontier, they don't need to re-enroll.

Release options in the Microsoft 365 admin center:

• Frontier (preview access): Opt in specific users and groups, or all users, to get eligible public preview features before general availability.
• Standard release (general availability): Receive updates as soon as they're generally available. This is the default.
• Deferred release (general availability): Receive eligible major updates approximately 30 days after Standard release begins, allowing more time for validation and readiness.

Learn more: Get started with the Microsoft Frontier Program

What and why

Microsoft is responding to an issue involving eight eMudhra intermediate certificate authority (CA) private keys, six associated with TLS and two with code signing. Because these keys could be recovered, they could potentially be used to create certificates or sign content that appeared to come from a trusted CA. The issue arose in eMudhra's certificate hierarchy and was not a compromise of Microsoft systems.

Microsoft is updating certificate trust to block affected certificate authorities and remove certificates associated with the affected hierarchies.

What and why

As previously announced in MC1448379 (August 5, 2026) and MC1488834 (October 5, 2026), the public preview of the MemberOf rule operator in Microsoft Entra ID is ending. Organizations using MemberOf in dynamic membership groups, dynamic administrative units (AUs), or entitlement management auto-assignment policies must replace these configurations by November 3, 2026.

Microsoft continues to improve the scale and reliability of dynamic membership processing. During the preview, Microsoft observed that use of MemberOf can affect dynamic membership processing across a tenant, even when only a single MemberOf rule is present. Because of this limitation, the preview functionality is being retired and is not recommended for production use.

Updated October 28, 2026: We have updated the timeline below. Thank you for your patience.

To help you manage metered consumption costs for Microsoft 365 Copilot Chat, we will introduce a new Message consumption usage report in the Microsoft 365 admin center. The new report will give you visibility into billed messages associated with your Microsoft 365 Copilot pay-as-you-go billing policies and includes total messages consumed, cumulative and daily time series, and messages per user, per billing policy, per agent, and per agent-user pair. The new report will roll out in preview. During the preview stage, the report will display a maximum of 30 days of message consumption history. Usage information from prior to May 3, 2025, will not be available in the report.

This message refers to Microsoft Copilot in a pay-as-you-go model. A Microsoft Copilot license is not required.

What and why

Microsoft Purview Endpoint Data Loss Prevention (DLP) is introducing the ability to protect sensitive files even when they reside in commonly excluded Windows folders such as AppData directories and temporary folders. Previously, files stored in these excluded paths were not subjected to Endpoint DLP policy enforcement. With this update, policy checks will apply during key egress actions, including copying, printing, saving to network shares, and uploading to cloud services, helping reduce the risk of sensitive data leaving your organization from these user-writable locations.

This message is associated with Microsoft 365 Roadmap ID 562992.

Updated October 28, 2026: We have updated the timeline. Thank you for your patience.

What and why

We're introducing targeted audience surveys in the Copilot dashboard. This feature enables authorized users to launch Microsoft Viva Pulse surveys for predefined Copilot user populations without creating or maintaining recipient lists.

Survey audiences are dynamically based on Copilot dashboard data and can be scoped using existing dashboard filters. This helps organizations gather feedback from Copilot users while reducing administrative effort associated with audience management.

This message is associated with Microsoft 365 Roadmap ID 568072.

Updated October 28, 2026: We have updated the timeline. Thank you for your patience.

What and why

We’re expanding analytics in the Microsoft Teams Pro Management portal to include utilization insights for bookable desks. IT admins will be able to better understand how desk spaces are being used across their organization, with insights into desk utilization, reservations, occupancy, and peak usage patterns. Desk-specific filters, including location and desk mode, will help admins analyze usage across their workplace and make more informed space planning decisions.

For utilization analytics to be enabled, a desk needs to have one or more peripheral device associated, and the desk needs to be licensed with Microsoft Teams Shared Space license or Microsoft Teams Shared Space - Single Space license.

This message is associated with Microsoft 365 Roadmap ID 570648

Updated October 27, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Purview is updating how legacy Microsoft Teams retention policies are applied. Some existing retention policies that are scoped to Teams currently also apply to Microsoft 365 Copilot interactions. Beginning with this rollout, these legacy policies will be treated as Teams-only policies and will no longer implicitly apply to Copilot workloads.

• Monitor performance in near real-time:Track key metrics such as queue backlog, service level, abandon rate, representative presence, available capacity, and conversations handled over time without refreshing the dashboard.
• Display live performance on wallboards: View continuously updated metrics in full-screen mode to provide a shared view of contact center performance.
• Analyze queue and representative performance: Drill down from high-level summaries to queue-level and representative-level views to identify performance changes and potential issues.
• Take action directly from the dashboard: Adjust representative queues, presence, skills, and capacity profiles within the supervisor experience.
• Configure performance thresholds: Set thresholds for key metrics and use color-coded indicators to identify At Risk and Critical conditions.

What and why

Microsoft is retiring SharePoint Server access through the standalone SharePoint mobile apps for iOS and Android. After this change, these apps will support SharePoint Online only.

What and why

We are retiring selected Search Analytics capabilities for the following search experiences:

• Microsoft/Bing Search, including Work Search
• Teams Search
• Outlook/WXP Search, including Word, Excel, and PowerPoint
• Windows Search Work results
• Microsoft365.com

This retirement applies to Summary, User/Query, and Answer Analytics associated with these search experiences within Search & intelligence > Insights in the Microsoft 365 admin center. This change is limited to the analytics capabilities listed above. It does not:

• Retire the Search & intelligence > Insights experience as a whole
• Affect SharePoint Search Analytics
• Affect Connector Analytics
• Change users' ability to search in any of the affected applications

What and why

We're updating the Join button experience in Outlook to use HTTPS meeting join URLs. Beginning the week of November 30, 2026, the Join button will no longer appear for meetings that contain only an HTTP join URL.

What and why

We’re improving the backup and restore experience in Microsoft Authenticator for Android. When setting up Authenticator on a new device, users will receive guidance tailored to whether they still have access to their previous device. They will also receive guidance on using Authenticator passkeys for cross-device sign-in. This experience is already available on iOS.

To use backup and restore on a new Android device, users must enable Google One backup and screen lock.

What and why

Edit with Copilot makes it easier to edit and transform your Excel workbooks on your phone using natural language. Copilot can continue working on your task even when you move away from the app, so you can come back when the work is ready. Chat mode also remains available when you want to ask questions and get insights without making changes to your workbook.

What and why

This is a reminder of the upcoming retirement of Microsoft-provided SMS and voice authentication in Microsoft Entra ID, previously announced in MC1426371 (July 13, 2026) and MC1434201 (GCC, July 20, 2026).

Microsoft-provided SMS and voice authentication will retire starting February 1, 2027. Complete your migration before rollout begins to avoid interrupting users' sign-in experience.

SMS and voice are vulnerable to phishing and SIM-swap attacks. Microsoft recommends passkeys for stronger, phishing-resistant protection. You can also migrate to another supported authentication method or retain SMS and voice by configuring a customer-managed telecom provider (CYOT) through the Microsoft Security Store.

Updated October 27, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft Entra will soon recognize Windows Hello for Business (WHfB) and macOS Platform Single Sign-On (PSSO) as standalone multifactor authentication (MFA) factors in supported authentication scenarios.

Today, WHfB and macOS PSSO can satisfy MFA requirements during primary sign-in, but users may still be required to register and use an additional passkey or authentication method for certain step-up authentication prompts, Authentication Strength policies, and sign-in frequency checks.

After this rollout, users who authenticate with WHfB or macOS PSSO will be able to satisfy supported MFA requirements without registering an additional passkey. This change helps organizations expand the use of phishing-resistant authentication methods and reduce reliance on less secure authentication methods. As part of this change, a user's WHfB and macOS PSSO credentials will be displayed in My Security Info as auto-registered passkeys.

Updated October 27, 2026: We have updated the timeline. Thank you for your patience.

What and why

We are improving the OneDrive sync experience on Windows desktop to provide clearer, more actionable guidance when file and folder paths exceed the supported 520-character limit. The updated experience will show exactly how many characters a path exceeds the limit and will provide a guided flow to rename or move affected items so they can sync successfully.

This improvement addresses a common OneDrive sync issue by reducing user confusion, minimizing workflow disruption, and helping users resolve errors faster.

This update is associated with Microsoft 365 Roadmap ID 557563.

(Updated October 27, 2026: Included reference and link to more guidance published in the Message center post MC1526468.)

What and why

Windows updates are now available to support the 2026 time zone changes in Manitoba, Alberta, and British Columbia. On November 1, 2026, clocks in affected regions will not be set back by one hour.

Manitoba will permanently stay on UTC-5, Alberta and affected locations will permanently stay on UTC-6, and most of British Columbia will permanently stay on UTC-7. The new Windows updates add region-specific time zones to support these changes.

Updated October 27, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft is introducing support for Microsoft Agent 365 agents that implement the Agent2Agent (A2A) protocol, allowing them to be used as connected agents in declarative agents built with Microsoft 365 Agents Toolkit.

This enhancement expands the types of external agent services that declarative agents can connect to. In addition to existing support for OpenAPI and Model Context Protocol (MCP) servers, declarative agents can now connect to Agent2Agent-enabled agents, enabling natural language interactions and support for more complex workflows.

This feature gives developers greater flexibility when building declarative agents while providing administrators centralized management and governance through the Microsoft 365 admin center.

What and why

Default Meeting Templates enable IT admins to automatically apply their organization’s preferred meeting options whenever users schedule a Teams meeting through Outlook or Teams calendar. This helps organizations apply meeting options (including protection meeting options) at scale, and reduce the need for organizers to manually configure meeting options.

What and why

This new capability enables admins the capability to manage Authoritative sources within the Copilot Search experience in the Microsoft 365 Admin Center. As part of current change admins will be able manage SharePoint Online (SPO) sites that can be deemed as authoritative content per their organization.

• Available only to Global admin and Global reader role.

What and why

Following the public preview announced in MC1301802, the Change Optics report for Exchange Online is now generally available for worldwide tenants. The report helps Exchange administrators identify email traffic that may be affected by upcoming service changes so they can investigate and remediate potential issues before enforcement occurs.

Learn more: The Change Optics report is now generally available in Exchange Online

Updated October 26, 2026: We have updated the timeline. Thank you for your patience.

What and why

We are updating the entry point for Copilot in Outlook to be more visually appealing and consistent. Located next to the Outlook ribbon, the Copilot entry point makes it easier for users to discover and use Copilot as they work. In addition to chat, it also surfaces contextual, AI-powered recommendations based on the task at hand, such as reading email, composing messages, or managing a calendar. With a single click, users can act on these suggestions to quickly summarize content, draft responses, organize information, and accomplish tasks more efficiently. The experience is designed to bring relevant Copilot capabilities closer to the user's workflow while providing a consistent Copilot experience across Microsoft 365 applications.

This update is associated with Microsoft 365 Roadmap ID 567007.

Updated October 26, 2026: We have updated the content and timeline. Thank you for your patience.

What and why

Microsoft is introducing Change organizer for eligible Outlook meetings and recurring meeting series. Users can ask another person in their organization to become the organizer, and the selected person must accept before ownership changes. This supports personal and team productivity by maintaining meeting continuity during role changes, leave, and offboarding.

What and why

New export improvements are coming to Cloud Update, making it easier for organizations to access and analyze device data. These enhancements will expand export capabilities across Inventory and Cloud Update device views, include additional device and update information, and allow admins to export filtered results so they can focus on the devices most relevant to their needs.

What and why

Microsoft is retiring AI Builder credits and replacing them with Copilot Credits. Organizations using AI Builder must arrange Copilot Credit capacity before their existing AI Builder credit entitlements expire, or sooner if those credits are exhausted, to avoid interruptions.

AI Builder features are not being retired. They will continue to be supported using Copilot Credits, bringing AI Builder and Microsoft Copilot Studio capabilities onto a common credit-based licensing model.

What and why

Microsoft Teams is extending malicious URL protection to provide near-real-time detection of malicious destinations embedded in QR codes shared in messages. Teams will analyze QR code destinations to identify potential phishing and fraud threats and display an additional warning when malicious content is detected.

Updated October 26, 2026: We have updated the timeline. Thank you for your patience.

What and why

Microsoft is rolling out new capabilities in Audio Overview to make it easier to navigate longer content, support enterprise information protection, and create audio overviews from more types of content.

Episodes

For longer and more content-rich notebooks, Audio Overview can organize the discussion into topic-based episodes. This makes it easier for users to navigate the audio and focus on different parts of the content.

Sensitivity labels when saving to OneDrive

Audio Overviews now support Microsoft Purview sensitivity labels when saved to OneDrive. If the source content includes sensitivity labels, the saved Audio Overview inherits the most restrictive label from its sources. Sensitivity labels apply to the saved file in OneDrive. Audio Overviews within the notebook are not yet sensitivity labeled.

More supported content types

Audio Overview can now understand and ground its discussion in additional types of content added to a notebook, including:

• OneNote pages
• Loop pages
• Plain text (.txt) files
• Emails
• Teams meetings
• Teams chats

Updated October 26, 2026: We have updated the timeline. Thank you for your patience.

What and why

We're introducing a new MessageContents table in Advanced Hunting for Microsoft Teams messages. This new table helps security operations teams investigate threats in Teams by providing access to Teams message snippets and associated message metadata during threat investigations.

This capability enhances security investigations by allowing authorized analysts to correlate Teams message activity with other security signals available in Advanced Hunting, helping organizations detect, investigate, and respond to threats more effectively.

Updated October 26, 2026: We have updated the timeline. Thank you for your patience.

What and why

Users will soon be able to register a passkey as their first multifactor authentication method. Previously, people had to set up an alternate MFA method like SMS or Voice before they could add a passkey (FIDO2), Windows Hello for Business, macOS Platform SSO. That extra step pushed users toward weaker methods and slowed the move to phishing-resistant sign-in. Now password-only users can go straight to a passkey, making it easier to adopt strong authentication from day one. As part of this work, we will also be enabling Authenticator App passwordless sign-in to be a user's first registered MFA method.

This post updates MC1510951 ((Updated) Windows updates are available for 2026 time zone changes in Canada, posted October 16, 2026).

On November 1, 2026, affected locations in British Columbia, Alberta, and Manitoba will not move clocks back and will remain on UTC-07:00, UTC-06:00, and UTC-05:00 respectively. Affected locations in the Northwest Territories (including Yellowknife and Inuvik) align with the Alberta change, and Northwestern Ontario aligns with the Manitoba change.

Windows and Microsoft 365 services depend on updated time zone definitions for correct scheduling and display behavior.

How this affects your organization

Confirmed impact

1. Outlook and Exchange Online (calendar): Users must move to the new time zone. Existing events do not migrate automatically. Recurring meetings require additional review.
2. Microsoft Teams Rooms on Windows: Some devices may display time one hour behind Windows until Edge/WebView2 is updated.

Potential impact (under validation)

1. Microsoft Teams (desktop, web, mobile) and other Teams devices
2. Outlook for iOS, Android, and Mac
3. Microsoft Bookings
4. Shifts
5. SharePoint Online
6. OneDrive

Introduction

We are introducing a new priority cleanup workflow in Microsoft Purview Data Lifecycle Management that allows administrators to permanently delete (hard delete) specific OneDrive and SharePoint content types, even when retention policies or holds are in place. This capability helps reduce data exposure risk from rapidly growing Copilot-related content while maintaining compliance through required eDiscovery admin review and approval.

This change is associated with Microsoft 365 Roadmap ID 558343.

Stage: 1. Restricted
Timing: When the tenant first exceeds its entitled storage capacity, known as time zero (T0)
Impact: Environment creation, copy, restore, and recover operations for sandbox and production type environments are blocked immediately when the tenant exceeds its entitled capacity.

Stage: 2. Administration mode
Timing: After 30 unresolved days from T0
Impact: Only administrators can sign in to *affected sandbox environments. All other users are blocked from accessing the environment.

Stage: 3. Disabled
Timing: After 90 unresolved days from T0
Impact: All users, including administrators, are blocked from accessing *affected sandbox environments; the environment data is retained and remains available for recovery after remediation. During this phase, customers can contact Microsoft Support for the sole purpose of directing data export options, if needed. All other mechanisms designed to resolve overage are also available to customers at this phase.

What and why

Users can now start a Copilot conversation directly from Teams search on iOS and Android. Microsoft Teams mobile is adding two ways to ask Copilot from search:

1. As users type two or more words in the search box, a suggestion to ask Copilot appears alongside usual search suggestions.
2. After users press Enter, an Ask Copilot button remains available at the top of the search results page.

Selecting either option opens Copilot with the user's query, so users can get an answer and ask follow-up questions without leaving search.

What and why

Adds support for alternate text on OneDrive/SharePoint-hosted images shared in Microsoft Teams, improving accessibility for users who rely on screen reader functionality.

What and why

We’re retiring the public preview opt-in setting for GitHub Copilot on the Viva Insights app settings page. After this change, GitHub Copilot metrics will be available by default in the Viva Insights Consumption dashboard for eligible tenants. This change provides a unified view of GitHub Copilot and Microsoft 365 Copilot adoption and usage across developers and knowledge workers.

What and why

Gain proactive visibility into meeting quality across your organization with AI-powered insights in Teams admin center that identify emerging patterns, highlight impacted users and locations, and surface likely causes with recommended actions. This helps IT administrators detect and address issues earlier, improve meeting quality, and stay ahead of potential disruptions.

What and why

For non-channel Microsoft Teams meetings, collaborative meeting notes, including Loop-powered meeting notes and Facilitator notes, will be stored in the meeting organizer’s OneDrive for Business instead of the OneDrive of the person who starts notes. This update provides more consistent ownership and management of meeting content while preserving the existing note-taking and collaboration experience for meeting participants.

Updated October 23, 2026: The content has been updated to provide additional clarity on admin permissions for the new device experience.

Earlier this year, we released the new single device experience that provides a single, consolidated view for device management, making it easier to access device information, monitor activity, use management tools, and perform device actions The new single device page is turned on by default. You can use the "Preview new device toggle" to turn it off and return to the original device page.

Starting with Intune’s September (2609) release, the new device page will become the default experience for all administrators, and the previous device page experience will no longer be available.

How this will affect your organization

Admins who navigate to Devices > All devices and select a device will automatically see the new device page experience. The legacy device page will no longer be available after this change.

All existing device management capabilities remain available. This update focuses on improving discoverability, usability, and navigation without removing existing management functionality.

With the new device experience, administrators must have the Managed devices/Update permission in addition to any permissions required for the specific device action they want to perform. For example, to change or remove a device’s primary user, an administrator must have both Managed devices/Update and Managed devices/Set primary user. Administrators who do not have Managed devices/Update may also be unable to perform actions such as renaming a device.

What you need to do to prepare

Update your documentation and review your admin permissions for device management actions as needed. We recommend becoming familiar with the updated interface before it becomes the default view.

To preview the new experience today:

1. In the Microsoft Intune admin center, navigate to Devices > All devices.
2. Select a device to view device-specific information, such as device properties, device activity, tools, and reports.

What and why

We are updating the Microsoft OneDrive web experience. As part of this update, the Create or upload button will move from the left navigation pane to the right side of the page, aligning the experience with SharePoint document libraries. The Create or upload button will also no longer appear in Libraries, Recycle Bin, Meetings, or Media. The available options for creating files and folders or uploading content will remain unchanged.

Note: Some users may receive this update sooner than others within your organization.

What and why

Microsoft is introducing Microsoft Graph APIs for Copilot cost management, giving organizations a programmatic way to manage Copilot credit spending policies, monitor credit balances, and handle end-user requests for additional credits.

Administrators and developers can use the APIs to retrieve tenant, user, and per-service credit balances; create, update, and delete spending policies; assign security groups to policies; configure service-specific settings; and set up email threshold alerts. They can also retrieve, approve, or reject credit requests.

These APIs integrate Copilot cost management with existing administration and FinOps processes. This initial release, available through the Microsoft Graph beta surface, focuses on spending-policy administration and balance information; detailed consumption reporting is not included.

What and why

We are increasing the maximum auto-expanding archive capacity for eligible Exchange Online archive mailboxes from 1.5 TB to 3 TB in Microsoft Purview Data Lifecycle Management. This enhancement helps organizations retain and manage larger volumes of archived email content without requiring manual archive expansion processes or support requests. Eligible mailboxes with auto-expanding archiving enabled will continue to grow automatically as needed.

What and why

We are retiring the ability for online participants to turn off IntelliFrame for their own view in meetings with a Microsoft Teams Room that has Cloud IntelliFrame enabled. This change provides all online participants with the same view of the room, as configured on the Teams Rooms device.

Currently, online participants using Microsoft Teams desktop on Windows and Mac can right-click the video tile of a Teams Room using Cloud IntelliFrame and select Turn off IntelliFrame. This switches to the standard room view only on their own Teams client.

What and why

We are introducing a new Copilot skill in PowerPoint that helps users create formal project kickoff presentations for kickoff meetings, project launches, and new-project alignment. The skill helps teams align on project goals, roles, milestones, scope, risks, schedule, success measures, and next steps.

Updated October 22, 2026: We have updated the content. Thank you for your patience.

What and why

To give users more choice and flexibility when working with AI in Microsoft Copilot, we're expanding the set of AI models available in Microsoft Copilot.

Starting today, GPT-6.1 Sol and Claude Sonnet 5.5 begin rolling out with usage-based billing in Cowork and Microsoft Copilot Studio.

GPT-6.1 Sol and Claude Sonnet 5.5 will also begin rolling out in phases across Word, Excel, PowerPoint, and Chat in the coming week as part of the Microsoft 365 Copilot user subscription license (USL). Limits apply to these models, but they are designed to support broad day-to-day AI usage across organizations and are implemented in such a way that the vast majority of users are not expected to reach them. Users approaching a limit will receive in-product notifications and can continue their work by switching to Auto mode or selecting another available model.

What and why

Azure PST Import provides a structured, PowerShell-based way for administrators to import PST files stored in Azure Blob Storage into Exchange Online mailboxes, which are commonly used to store archived Outlook mailbox content. This capability helps organizations migrate historical email data in a controlled and auditable way by validating readiness before importing and by providing reports throughout the process. The process starts by creating an Azure PST Import endpoint to establish the connection between Azure storage and Exchange Online. Administrators then run a migration batch in Analyze mode to review readiness and validate the input before proceeding. Once the analysis results are reviewed, they use those results to create and start the import batch, which begins importing the PST files into the specified mailboxes.

Introduction

Viva Engage will stop sending email notifications to users who do not have a valid mailbox or routable email destination. Previously, email notifications could still be attempted for these users, resulting in repeated delivery retries, increased load on email systems, and, in some cases, delays to important business communications.

This change reduces unnecessary email traffic, improves delivery efficiency, and helps ensure important communications are delivered reliably and on time.

Users with supported mailbox configurations, including cloud mailboxes, on-premises mailboxes, shared mailboxes, and other routable email destinations, will continue to receive Viva Engage email notifications as expected.

Notifications delivered through supported channels such as Microsoft Teams remain unaffected.
