Chris,
Thanks for your input. Reading the other replies here has gotten me thinking
more about using VPN & PPTP. If we were to replace our existing NAT router
with one which supports VPN, wouldn't that give us a way to configure
multiple users, or are we still running into the same problem with NAT?
(Note: I realize this is slightly off-topic..please bear with me)

The whole point at the moment is that we do not have a server capable of
handling this kind of thing (we have one aging NT 4.0 file server) and we do
not, at the moment, have a budget to upgrade to an XP Server (which would
then permit us to consider Exchange). I'm hoping to find some sort of
solution which allows several users to access their individual workstations.
So if I'm understanding this correctly, ActiveSync will not allow custom
port configuration?

I guess I'll post a related post in a VPN discussion group about how to work
with that technology, but in the meantime, if I could get some clarification
about custom port config in ActiveSync I'd really appreciate it. Thanks!

Alternatively, is there a directory - or does anyone have a suggestion - for
3rd party services which offer Exchange service? If it doesn't need to be
locally hosted, this may be a viable route for us.
