After furious head scratching, cbrack asked:

| I recently setup a computer for one of my users. I installed, among
| other things, Office 2000 Pro SP2 over Windows XP Pro SP2. Normally
| when I do this, I install everything, start Outlook, and select the
| wizard options that will connect the user to their Exchange mailbox.
| In this case, the user started the Outlook wizard and attempted the
| setup on their own. Now, email can be received but not sent from
| Outlook, and when I attempt to reconfigure, Exchange isn't an option.
| I'm obviously not an Outlook guru, so can anybody offer a fix to
| connect to the user's Exchange mailbox and locate the Exchange
| address book?
