Keefy, I use hotmail with Outlook Express. All you need to do is go to the 'tools' menu, then to 'email accounts', select the button so you either set up a new account or change an exisiting one, follow the instructions through and you should get to a page that allows you to choose the type of server (either a Microsoft exchange, POP3 etc...) all you need to do there is choose the http option and configure the hotmail account into it by typing in your email address and password.
Of course it depends what version of outlook you're on and I'm going by memory on the above, but it's not usually too much of a fiddle.
