With our Turnpike software, you just point the workstations to the

have email data available on the whole network. Nice and easy.

I cannot seem to replicate this set up under Outlook. It seems like
you have to set up email profiles on each machine and the emails are
collected/delivered from the ISP individually by each machine and
stored locally.

Correct. Outlook, like all POP/SMTP clients, requires a mail server to
perform the message routing duties. It in itself is not a router.

Is there any way round this?

No.

I understand that I could resolve it by
installing MS Exchange Server, but this requires 64 bit Windows (?)

Exchange 2003 will run on 32 bit servers and will support Outlook 2007,
although there a some features of Outlook 2007 that are not available unless
connected to an Exchange 2007 server.

and we are quite happy using POP3.

There are plenty of Windows-based POP/SMTP servers available for purchase
and there are also some available free. Windows Server 2003 comes with a
built-in POP/SMTP server as well and will run on 32 bit systems. If you
wish to host your own mail service for internal use only, there's nothing to
stop you. I don't know much about the WIndows Serrver 2003 Email services,
but I can conceive of it being able to act as Turnpike did.
