email backup

[p0lish]

im looking for a utility to backup automatically emails on 8 computers at my work. i would like them stored as the seperate email files, not backed up into one large single file, to allow organization of emails by job/work order. i've looked at a few, but they all create a single backup file. anyone know of a program like this? all computers are newer and using microsoft office 2003 and Outlook, not outlook express.

thanks,
bill
