Recently updated Exchange 2010 to SP3/RU4. Problem is with Outlook 2010/2013 clients with automapped folders to "Full Permission" mailboxes. Archive folders all appear with the same name as the owner's mailbox. See example below of my mailbox. The second archive folder should say HelpDesk. If you open the archive folders they are correct for the mailbox. However, other uses have several mailboxes assigned and can't determine which one is which.
