Older versions of Azure AD Connect will be retired on February 29th, 2024

If you are using an older version of Azure AD Connect, you might want to consider upgrading it. Yesterday, Microsoft published new information on changes to come.

The Azure AD Connect product team is constantly making updates to Azure AD Connect Sync to ensure optimal security and performance of organizations’ synchronization processes.

Therefore, Microsoft retires older versions of Azure AD Connect on February 29th, 2024. On that date versions published before 5 May 2018 will be retired.

Older versions of Azure AD Connect and Windows Server

Azure AD Connect version 1.1.751.0, and all older versions of Azure AD Connect, will be retired at this point.

If you’re running Azure AD Connect on Windows Server 2012 or Windows Server 2012 R2, it is also good to keep in mind that these Operating Systems will reach their end of support on October 10th, 2023 (four months earlier).


Action required
