I've just upgraded my machine to Win2000 and Office 2000 but i'm having problems with Outlook 2000, Its all installed o.k but i keep getting the following error message, "Unable to log MS Exchange Address Book onto server. Cannot resolve name" when I set it up for the first time. Their is nothing wrong with the name or mailbox and i have even tried going back to Outlook98 but i get the same message. HELP.<br><br>
