I personal use ThunderBird as it has some nice features.
Disable javascript, Don't load external images, and Junk mail controls.

I even have it setup to leave the messages on the server for 7 days or until I delete them. This way I get my junk mail deleted from the server but I can use the web mail for my normal stuff.
Here is a different approach, are you running XP? Are you on a static IP? You could just remote desktop to your PC and use Outlook from the PC you currently have access to.
