Hi Amir,

first you had to install Outlook 2000 or earlier on the Backup Exec Server,
and than you must Create a Mailbox for your Backup Exec User. After you create
the Mailbox accout you must give the Backup Exec Service Account Administrativ
Rights to your Exchange Server. If the Service Accout has the Rights to access
Every Mailbox, you logon, with the Service Account, to your Backup Exec Server
and than you should select the Mailboxes.
