Remove account from Outlook after user license is removed

[jsparlin]

As an admin, I am frequently setup with access to other user's accounts. Sometimes those accounts have their license removed while I am still setup as a delegate on that mailbox. When the license is removed the account no longer has a mailbox so I can't remove the delegate access in Office 365 but the account persists in Outlook long after the mailbox is gone. When I try to close or remove the mailbox in Outlook it fails saying it is tied to my account. Is there a way to remove this mailbox from my Outlook without granting the account another license or rebuilding my Outlook profile? Or is there a way to remove the delegate access from the account even though there's no mailbox?

Remove the delegate permissions before removing the license? You can also use the -ClearAutomapping switch to just remove automapped mailboxes: https://www.michev.info/Blog/Post/1382/removing-automapping-and-resetting-default-mailbox-permission...
