I can't open another user's mailbox or folders.
You may be using a more current version of Microsoft Exchange Server than the person who's mailbox you are trying to open.
You or the other person may be working offline.
I can't delete, move, or rename a specific folder.
You may be trying to perform one of these operations on the default Microsoft Outlook folders (Inbox, Calendar, Contacts, etc.). You can only perform these operations on folders you create.
