Beginning in July 2026, we will begin notifying customers through the M365 Message Center, Entra Connect Health, and targeted emails about their individual transition timelines. The transition will be rolled out in phases, and we will reach out directly to each organization when their assigned transition window begins. This phased approach ensures that we can provide tailored guidance and support to all our customers.

  • Initial phases: In the first waves, we will focus on tenants for whom Entra Cloud Sync already meets all their identity synchronization needs. If your organization relies on advanced features or has a large directory, you will _not_ be among the initial targeted groups. We will prioritize early transitions for customers with straightforward configurations that are fully supported by Entra Cloud Sync’s current capabilities.
  • Subsequent phases: As Entra Cloud Sync’s capabilities expand, we will progressively notify the later groups and ensure they can transition successfully once equivalent support is available in Entra Cloud Sync

We are committed to supporting you by providing tooling and documentation for the transition to Entra Cloud Sync.
