Sharing Outlook 2003 across a small network - please help

[BigMrC]

I'm helping set up a small network. They have 3 pc's linked together via a router. Pc's can see each other and share folders no problem.
They have one email account, currently being controlled from one of the pc's.
This pc sends/receives and has various email folders set up.
They all have outlook 2003 installed but how does each see the same folders.
E.g. an email comes in - all three pc's should receive it, when it gets put in a folder the folder is updated on each pc.
So basically three pc's sharing the same outlook.
Don't want to have to get Exchange for them, is there a way to do this. I thought you could have the pst file on a shared drive and all three outlooks good read from this, but seems you can't share a pst file.
Any help much appreciated.

PST files also can't be open by more than one user at a time. What kind of email account are you using? Is it one you have setup or is it through someone else?

it's through someone else - ie an external ISP
