I'm not sure which newsgroup this question belongs in, so I am crossposting.
Please forgive me if I've violated nettiquette.

My client is running Office 2000 on a win2000 machine.  At some time in the
past, someone either configured it to use MS Exchange or checked the "I'll
manually install email service later" (or whatever it actually says).  When
Outlook starts up for the user, the first thing it askes for is the name of
the server and email user account.  As this location does not use MS
Exchange, there is no server.  As a result, the only thing that Outlook will
show without a valid Exchange server is hardrives and the "my documents"
folder.  But the Options and email accounts selection of the "Tools"
dropdown menu are greyed out (Options) or missing (Email accounts).

Otherwise, if you click "no," Outlook simply exits with no chance to change
it over to using Internet Mail (ie., a pop/smtp server).

I have uninstalled Outlook from the machine and then reinstalled it, but
nothing works.  It is impractical and too disruptive in their environment to
create a new domain userid and start from scratch.

How do I unconfigure this mess so I can properly define my customer's userid
to use the email he has instead of Exchange? I suspect that I need a tweak
something in the registry but I don't know where to begin.

Any advice would be gratefully accepted.  Thanks in advance.

Jim.
