Microsoft will stop all support on versions 1.x of Azure AD Connect on 31st August, 2022. This is due to these earlier versions containing components of SQL Server 2012, which themselves are no longer supported. In order to avoid running the unsupported versions, it is recommended that users upgrade to versions 2.x of Microsoft Azure AD Connect or to Azure AD Connect cloud sync.
This upgrade should not come as a shock to users. It was originally announced in September 2021. However, upgrading at that time had some major disadvantages. At that time 2.x versions had no auto-upgrade functionality. This has since been added.
If you are still running a 1.x version, then you need to act fast. But, even if you are running a 2.x version, it is recommended that you upgrade to the latest version (18.104.22.168). By doing so you will be up to date with all the features and security fixes and you can take advantage the Auto-upgrade function which is not available in the earlier iterations of 2.x.
What happens if I don’t upgrade?
Microsoft expects Transport Layer Security (TLS) 1.0/1.1 to be obsolete by 2022. You need to make sure that these protocols are no longer used, because your service could stop working.
It is intended that Active Directory Authentication Library (ADAL) will no longer be supported after December 2022. When ADAL is no longer supported, authentication could stop working. This will block Azure AD Connect from functioning correctly.
Microsoft recommends upgrading to Azure AD Connect V2 by December 2022.
