I've just bought a new laptop with Vista Business and Office 2007. I used
the "Easy Transfer" feature to bring all my outlook data from my old machine
(Office XP). Now I have a problem that I can't use my contacts in the
address book. The contacts folder is there and I can see all the contacts in
it.

I can right-click on the contacts folder, go into Properties and go to the
Windows Address Book tab, but the box to tick for "Show this folder as an
e-mail address book" is greyed-out (disabled) and I can't select it. Does
anyone know how to enable it?
