Undelegated mailboxes wont stop auto mapping to User
- Jul 23, 2018
You can try using the –ClearAutoMapping flag for Remove-MailboxPermission, I've posted some examples here: https://www.michev.info/Blog/Post/1382/removing-automapping-and-resetting-default-mailbox-permissions-in-exchange-online
If those mailboxes previously existed on-premises, you might need to clean up the AD attributes as well, msExchDelegateListLink in specific.

Hi Vasil,
Thanks, this solved my issue! Clearing the mapping did the trick!
