What happens if you click on tools>address book?
"if a go to edit, find and then people...type in a new",how is it lost.
Maybe this LINKwill help.
I've kost my address book. I'm using a SonyVaio laptop with XP-HE with SP2. I use outlook express 6.0 for e-mail. Somehow it has disappeared from sight. It must be somewhere because if a go to edit, find and then people...type in a new, more often than not (but not always)the e-mail address appears.
