Everybody repeat after me
Outlook and Outlook Express are scum, scum, scum!
Hotmail is one of the better web based mail systems and i only use it so i can access it wherever i am, home or uni. Due to security restrictions we cant setup the mail clients to check other pop addresses, though i am trying to get round the admin.
As far as mail clients go i love pegasus, its free, easy and a very good program.
