Roaming user

Hope someone can give me some pointers. I have a user with a laptop running Win XP Pro who travels between offices and needs to be able to log onto both servers (Windows 2003 server), use printers in both locations and be able to retrieve his email. Setting him up as a user in both locations isnt a problem. The problem arises when it comes to his email. We use Pop3 and his email is distributed to the server in the main office. What would I need to do to be able to retrieve his email from a different server?

 

Only way to retrieve the email is to set up a central Exchange server to allow all users to retrieve from any location. Otherwise he will have to have a VPN connection to get the email from the other server.
