Download old Azure AD Connect versions / Entra Connect Sync [Updated May 2025]

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.

• On August 31, 2022, all 1.x versions of Azure AD Connect were retired by Microsoft because they include SQL Server 2012 components that are no longer be supported. You can find old versions on this page to test your migration to 2.x versions.
• Since AAD Connect 2.0.30, Windows Server 2016 is required.
