Update 1 – 31/032021

Microsoft released the new v. this fixed a bug in the previous release, because after upgrade to that release, the Azure AD Connect Health feature was not registered correctly and did not work. When you installed please do a upgrade to the new release.

Microsoft has released a new Version of Azure AD Connect. The new release going a big step forward from to and brings a lots of improvements and changes.

Please note:

This release changes the sync process to the new Azure AD V2 endpoint and is not supported for the German national cloud, the Chinese national cloud and the US government cloud. Please be aware of this notes and only use this version in Global Cloud Tenants or switch back to V1 endpoint, when you install this version in National Cloud environments.

I install the new relase on the weekend for a customer, because of changing the Azure AD Connect server. The new relase allows to import settings from a previous version. The new relase brings a lot of new features:

  • This release defaults the AADConnect server to the new V2 end point
  • This release require a full sync after installation
  • This version changes the synchronization to the new Azure AD V2 endpoint
  • This release is only supported for Global Cloud user – if you using National cloud environments, please take a look at the MS Docs article for futher details



The upgrade is quite simple, download the Azure AD Connect release from the official Microsoft download site. Upload it to the new server and start the setup process. The installation will stop the sync services and will restart them with a full synchronization after installation.


In some customer environments I see a little error in the Portal status. The Azure AD sync service shows a regulary sync process, but the portal shows that the last sync process is older then some hours. This is fixed with the release!

I would be interested if someone has the same conspicuousness, then leave me a comment with pleasure.
