i have my hotmail account working in outlook xp.
this is how i did it
1. opened outlook (well duh... lol)
2. went to "Tools", "Email accounts"
3. selected "Add new email account" and clicked next
4. selected "HTTP" and clicked next
5. (hotmail is already selected at right side... change to msn if u use msn)
6. enter in your name, email address, username and password
7. click next/finish (cant remember offhand which it was)
it synchronises all folders to a new folder on my outlook (i think you gotta select "view folders" from the "View" menu to see it - not sure - i always have view folders on)
