How to Connect to Microsoft Outlook with Mac OS X?

I teach at a college in Israel. For the most part I don’t use the College system at all – except for mail, through Microsoft Outlook, which I was also using on my PC. Recently I purchased a Mac Os X with Snow Leopard operating having been told I could access Microsoft Outlook. When I tried doing it, it didn’t succeed. The first window asked for my email and password and found the system. But then it asked me for “incoming mail server” and gave me four options: POP, IMAP, Exchange 2007, or Exchange IMAP. None of them worked. The IT people at my college had no idea how to help (so they gave me this link). Any suggestions?
