Eu encontrei este aqui :
Open Outlook. Go Tools, Email Accounts. Check view or change existing email accounts. Click Next. Make sure the "Deliver new email to the following location:" is set to "Mailbox - Your mailbox name" not a personal or pst folder. This will leave all the messages on the server and you will be able to view them from home computer as well
O mesmo problema também é mencionado aqui com uma correção semelhante descrita Espero que ajude
