I exported a file from my contact group (I have Outlook 2003, Windows XP) to
a csv. file. I don't know if that had anything to do with it, but the next
day, my Outlook contact file arbitrarily had shrunk from 144 contacts & notes
to 32.

I'm a novice, but use Microsoft Office Outlook for keeping track of all my
prospects. Please tell me how to retrieve the lost contacts. (How can I keep
it from happening again?)
