I have a user that left the organization that was a "manager" of multiple dist. groups. We need to keep the mailbox active for now (acct. is disabled), but I want to remove this user from all the DG's that they managed ("Managed By" field in the 'Group Information' tab).
Is there a way via powershell to simply do this? I assume there has to be, by a search didn't turn up much. And I don't want to manually remove this person from hundreds of lists by hand.
Thanks.
