This page is updated as soon as a new version of Azure AD Connect/Entra Connect Sync is available.
If you work with Microsoft 365, Azure AD Connect (Entra Connect Sync) is the masterpiece to synchronize the on-premise Active Directory to Azure Active Directory.
Microsoft provides 12 months support of each Azure AD Connect version but they provide only the latest version.
This page is here to fill this gap.
Get an Azure AD Connect older versions can be useful, for example, you may need perform migration tests or update your current AADConnect to get some specific settings (export settings before switching to 2016, etc.). Or you may just need the latest version supported by Windows Server 2012R2.
Some notes:
- Mandatory Upgrade Required: 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, we released this version with a back-end service change that hardens our services. Upgrade before this deadline to avoid any service disruption. If you're unable to upgrade before the deadline, all synchronization services will fail until you upgrade to the latest version.

Make sure you meet the minimum requirements including .NET Framework 4.7.2 and TLS 1.2.
