AD Connect problems

[Stefan Kießig]

Hello,
I have problems with AD Connect.
AD Connect was used to provision users from internal AD to Azure AD. After some time there was a problem with the sync of AD Connect and changes in AD.
As a result the users were converted to pure Azure AD users.
Now I have to bring the two users back together. The user attributes are all the same but AD Connect does not bring the users together.

Regards
Stefan

Hi, check out this article. https://docs.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-install-existing-tenan...

If a soft match on the SMTP address is not bringing the accounts together, then you may need to do a hard match using the immutable ID.

I had to reinstall the ad connect. 

There was an error in the datebase
