Try this...
I have no idea if this will work, but try putting this information in Mail (from the help section of hotmail):
In Outlook Express, click Accounts on the Tools menu.
In the Internet Accounts dialog box, click Add, and then click Mail.
On the first page of the Internet Connection Wizard, type your full name, and then click Next.
On the Internet E-mail Address page, type your full Hotmail address (name@hotmail.com).
On the E-mail Server Name page, click HTTP in the My incoming mail server is box.
In the box My HTTP service provider is, click Hotmail or Other.
If the box Incoming mail server is displayed, type
http://services.msn.com/svcs/hotmail/httpmail.asp.
On the Internet Mail Logon page, type your account name and password in the respective boxes. Your account name is the first half of your MSN Hotmail e-mail address (the information before the @ sign).
Click Finish to add your Hotmail account to Outlook Express.
