Configure retention for Microsoft 365 Copilot memory to help preserve historical versions of memory items for security, compliance, and investigation scenarios. Copilot memory includes saved memories and details inferred from chat history that enable more personalized and context-aware Copilot experiences. Copilot memory items are stored in a hidden folder in the user’s Exchange mailbox. This capability will enable retention and versioning support for inactive memory items so that administrators can maintain visibility into memory changes while active memory continues to be managed by the Copilot experience.

What and why
Microsoft Purview Data Lifecycle Management is introducing retention support for Microsoft 365 Copilot memory. Copilot memory includes saved memories, details inferred from chat history, and custom instructions that help provide personalized and context-aware Copilot experiences.
With this update, organizations will be able to retain inactive versions of Copilot memory items for compliance, governance, and investigation purposes. When memory items are updated or deleted, historical versions can be preserved according to your organization's retention configuration, helping compliance teams understand how memory content changes over time while supporting enterprise-ready compliance requirements.
