Hi @CagayakeGirlsPB ,
Do you have any operations before this issue occurred?
In my experience, we recommend you go to “change the group name in AD” and look for if you have University group in the right side pane. If CsAdministrator (among other new Universal groups that begin with Cs) is present, Active Directory replication has been successful. Then you can run the command “Get-CsAdForest” to make sure if the forest has been prepared.
