Hello; I run Exchange 5.5 sp4 on Windows 2000 member server on our NT 4.0 domain. I had a complaint today regarding our HR person accessing someone else?s mailbox. I checked permissions within Exchange Admin and she does not have the permission to do this. Even when I check the Mailbox Resources HR is listed as being logon to this other person?s mailbox. She does not know the admin password so how can she view someone else?s mailbox? I've checked all the permissions I know of within Exchage Admin and am baffled. I also checked the person who suspects that HR is reading his email within the Outlook client configuration to see if somehow he delegated this right but the HR person is not listed within the Outlook as having permission to his mailbox. How can someone besides the Exchange Admin have permission to view someone else's mailbox? Any help would be greatly appreciated.
