We recently upgraded to Outlook 2003 from Outlook 2000. On more than half of the desktops upgraded the Email Address is now displaying in the Display As: field which used to contain just the "Full Name" or in some cases the Full Name and address in parenthesis; i.e. "User Name (UserName@MyDomain.com)".
This issue is really irritating for the Sales and Marketing types in my organisation (which does give me some small pleasure), but on the other hand, they are the people with the thousands of contacts, and they have some right to be annoyed. I have looked in any number of resources to see how to change this but can't seem to figure it out, other than record by record.
