I'm creating an exchange 2003 mailbox for an AD user. It has done something, because the exchange tabs are added to the user's properties. However, no mailbox has been added to Exchange server. (it just doesn't appear in the mailbox store). Also, the exchange security settings for this user's mailbox are set incorrectly as you can see in the image below:
Also, when the user tries to add this Exchange account to his Outlook, he receives the following error:
"Name not found".
