How do I configure a users Outlook Express???

Hi everyone:

I have exchange 2000 running at the office and a user wants to retireve his
intraoffice emails from the exchange server using Outlook express on his
home computer.What will be the proper configuration so he can retrieve all
his intraoffice emails when he is working from home. He doesn't want to use
Outlook Web Access.

Thanks to all in advance
