I am using Server 2003 Std. with Exchange 2003, and outlook is 2003 is
running on Windows XP SP2. When I go to Mail in Control Panel and choose Add
new e-mail account. Then I choose Microsoft Exchange Server and it askes for
the server name (test4), I leave the check box in the Use Cached Exchange
Mode, and put in my user id (I have also tried my full name here). When I
click on Check name, it comes back with the error message, "Unable to
complete the request. The bookmark is not valid." When I click on Ok, it
brings up another window to try the server name and user name again.
Sometimes on the second attempt it says, "Unable to resolved the server or
user id." I can ping the server by name from the machine, and the machine
from the server.

Thanks.
