You'd have to upgrade Outlook to XP or 2003, which can handle Exchange &
Internet Mail in the same profile.
Or, my preferred suggestion - get rid of the POP and host your domain's mail
in Exchange. A lot easier. One stop shopping. Hosting your own domain's mail
will be a lot easier to administer (only one point of entry/exit), mail will
be faster, you'll be able to use OWA and Out of Office, you can easily
assign multiple addresses to each user, can use mail-enabled public folders,
publicly addressable distribution lists/groups, and can scan all
inbound/outbound mail for viruses using Exchange AV software on the server
rather than relying on client AV software.

You can do this even with dialup/ISDN (get an ISP who supports ETRN) .
If you have broadband but with a dynamic IP (such as a cable modem/ADSL
account):
You can use a dynamic DNS host such as
www.dyndns.org - you set up an
account, such as yourcompany.dnsalias.com, and whomever hosts your public
DNS should set your primary MX record to point to yourcompany.dnsalias.com.
Open up port 25 inbound in your firewall or router, direct all traffic to
your internal IP for the Exchange server.
You run a service on your server (software available for download from the
dyndns website) and set it up to update dyndns with your current dynamic
IP.
