Win2000 Server Email Storage .mbx files - Help Newbie!!!

[poppet]

I have inherited a system running;
Win2K server (Sp4)
Microsoft Exchange 2000 (Sp4) &
ISA Server 2000 (Sp2).
We currently have our mail delivered in pop3 format & have a third
party application (exchange pop3) running which then transfers messages
to Exchange after converting.
This machine is set up as a Primary Domain Controller.
There are a total of 15 client machines all connecting to this m/c all
of which have user accounts set up & mailboxes allocated.
My problem is at present a number of these client machines are running
Outlook 2002 (Sp3) & their mail is stored locally on their machines in
..pst files.
I would like to store all mail on server in .mbx files.
However when trying to alter the setings in outlook on client m/c by
selecting;
File >
Data File Management >
Add
The only types it shows available to select are personal folders file
(.pst)
Could anyone please help by if possible directing me in how this could
be done?

Outlook can't use MBX files.
