Unable to remove permission from archive
I have a permission that I can't get rid of.
At one time I granted User B full access to User A mailbox in Exchange 2010. Months later, User B has had all access to User A mailbox removed.
Both mailboxes and user accounts in AD are fully active.
User B permission to User A archive never went away. I have tried zapping and re-syncing the archive with no success. The permission keeps reappearing.
How can I remove this permission?
