I'm in an office with 5 networked computers. all incoming/outgoing mail uses
the same address (POP3 account). A single machine running Outlook Express is
used by all of us, in rotation, for email. This is inconvenient and
inefficient!

We all have Office (and can install Outlook). Is it possible to set up a
system whereby all the machines can view the same inbox, outbox, and saved
folders (stored just on a single machine), and that changes made by one user
(e.g. marking an email as 'read') are reflected on everyone's screens?
Ideally all machines would be viewing the folders simultaneously, but even
non-simultaneously would be an improvement on the present.

The system would have to deal with (comparatively) large volumes of email -
several folders have tens of thousands emails and we receive & send hundreds
(or more) of genuine emails each day.

Thanks,

Julz

P.S. This question is being cross-posted in the general Outlook folder.
