I had this exact same issue two weeks ago. Technet Q163576 turned out to be it for me.
Found it with a Technet Search; "Address Book was unable to log on" -sp -----Original Message----- From: Dan Phan [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 15, 2002 10:29 AM To: MS-Exchange Admin Issues Subject: Can't access Exchange Server Hi everyone, I have a client who has a problem connecting to the Exchange Server 5.5 SP4 using Outlook 2000-SR2 client. The following error occurs after clicking on the "Check Name" box under "Microsoft Exchange Server" window: "The name could not be resolved. The Microsoft Exchange Address Book was unable to log on to the Microsoft Exchange Server computer. Contact your system administrator if the problem persists." And if I use another computer and log in to the Exchange Server as this user, there isn't any problem connecting. Did anyone run across this problem before and how to resolve it? Your help will be appreciated.
