Unlike Gmail, Microsoft's Hotmail does not offer free POP3 access to it's mail server. This means that you cannot use an e-mail client such as Microsoft Outlook and connect to Hotmail (unless you have Windows Live Mail Plus subscription). If you try to do so without a subscription, you will be greeted with the error message "Access to Hotmail via Outlook and Outlook Express now requires a subscription. Please sign up at http://join.msn.com/general/Email"."
Well there is an application that allows you connect to Free version of Hotmail using Outlook 2003 and 2007; Microsoft Outlook Connector. This utility is released by Microsoft itself so you dont need to wonder why it only supports Outlook 2003/2007 clients.
