Hi I have implemented a "Shared hosting with Exchange 2003" in a lab environment and almost everything seems to work just fine. The only thing that I can't get to work is automatic logon to the mail-server with Outlook 2003. I have followed Amit Zinman's excelent article in this link http://www.msexchange.org/tutorials/Shared_Hosting_Exchange_2003_Part1.html, but I'm stil not able to logon automaticaly. Mr. Zinman's article doesn't state that this shuld be posible, only to logon with the external domain name. And that works fine. But is it possible to have Outlook to log on automatically in this scenario?
