Microsoft have a Help item called "Contacts are missing when I cllick

I can follow their advice as far as to "Reset Oultook Address Book
settings" and I get as far as Step 2.1 but cannot remove the Outlook
Address Book as the Remove function is greyed out.
What else can I do?

That's one of the problems with OL 2007. It doesn't allow you to remove the
address book service from the mail profile. You need to start with a new
profile.
