We are having a problem where the directory connector is no longer working. At first the error was “AN unhandled server error was encountered” but when I ran the application as administrator it gave a more specific error: Resource ##### does not exist or one of its queried reference-property objects are not present" When I dig into Azure AD, the #### is associated with a deleted user. The group we are using to sync users does not have this deleted user in it, nor was that user ever in the group so I am at a loss for the sudden failure of the sync. One thing I tried to do during troubleshooting was to restore the user to active. When I did that, the error went to the next deleted user in our tenant. Any suggestions?
Fixed with a new BETA of the directory sync app.
