Issue;-
While removing/disabling a user from Lync we got an error ‘Active Directory operation failed on “dc”. You cannot retry this operation:”insufficient access rights to perform the operation. Please refer below screenshot.
Solution:-
Solution was so simple even though I took lot of time to find the solution. “Protect object from accidental deletion” was set for the account from AD that is the reason it was not allowing to delete.
From Active Directory users and computer find the user and go to ‘Object’ from properties you can find this settings.
