"User A" is having an issue with his mail. I logged in to Exchange ecp, Gave myself delegate permissions to his mail, opened my mail and took care of his issue. I went back to ecp removed myself and then restarted outlook and I still have access to his mail, cannot remove it from my list, Can see all his mail. I ran Get-MailboxFolderPermission -Identity "usera" and only his secretary shows up.
How can I remove myself from his mail? I don't want to see his mail.
