When you say "I have just set up a new account in Outlook 2003" what
EXACTLY do you mean?
Do you mean you have set up a new Outlook profile, in which case you need
to copy the emails from your old profile to your new, or, do you mean you
have set up a new POP account? In which case, your old emails are still in
your current pst file.
Please give us some more information as to your setup, your ISP, and what
exactly you did.
