No, you won't lose mail, just like you won't lose Word documents.

I have an older computer running Windows XP and Office 2003. I've run into
a
couple of issues which I believe will be resolved by reinstalling Office.
My
concern, however, is losing my emails and contacts in Outlook. If I
unistall
the current software and then reinstall it again, will I lose the emails
and
contacts or are they stored in a data file which will remain on my
computer
after the unistall?
