[Wlug] WPI Exchange Help

So I'm new to the Linux community and I could use a little help. I'm trying to setup exchange to work through Evolution Mail on Ubuntu 8.10. I can't seem to set it up correctly. I feel like i have all the necessary info like the OWA URL, which I think is https://exchange.wpi.edu/owa/ . Please advise as to whether I need to specify the DOMAIN\User which doesn't work or if there is a better client for setting up exchange at WPI. Thanks, Ship
