I ran into this recently when a gal in the office got married. Now, however, a lot of internal people get mail bounced when their Outlook tries to send to the "user name" as opposed to the e-mail address. Here is an example:
----------------------------- ERROR REPORT -----------------------------
Message in error from:
Bob Smith / scalix0/CN=Smith, Bob
------------------------------------------------------------------------
Message could not be delivered to the following recipient:
Mary Jones / scalix0/CN=Jones, Mary
because: 'Recipient name not found at destination' [OM 9300]
------------------------------------------------------------------------
Where "Mary Jones" is the maiden name. Isn't there a way to alias this?
I guess it stems from the frustrating way Outlook imports e-mail addresses from Scalix. (See also
