Microsoft Entra Connect Sync upgrade required before September 30, 2026!
All synchronization services in Microsoft Entra Connect Sync will STOP working on September 30, 2026 if you're not on at least version 2.5.79.0.
In May 2025, Microsoft released this version with a back-end service change that hardens its services. Upgrade before this deadline to avoid any service disruption.
Microsoft strongly recommends upgrading to the latest available version 2.6.84.0, rather than only meeting the minimum version requirement.
Version 2.6.84.0 includes security fixes and is the current recommended release.
If you're unable to upgrade before the deadline, all synchronization services will FAIL until you upgrade.
The Microsoft Entra Connect Sync .msi installation file is exclusively available on Microsoft Entra Admin Center.
Make sure you meet the minimum requirements, including .NET Framework 4.7.2 and TLS 1.2.
