Outlook Backup

[Nabil]

I am trying to use the new add in feature of backing
the .pst file in an XP computer. I have two accounts with
two different outlook profiles. I can only backup one of
them and whenI tried to install the program under the
second user, it would not let me and required that I
uninstall first.

Is their a way to back up both user's pst files?

Thanks
