Motorola Sidekick Slide

I have a sidekick slide and a nice feature is the new setup of the mail. It allows you to add external email accounts and access them the same way you access T-Mail. I'm wondering if anyone has successfully added an MSN email account or knows how to successfully add an MSN email account. I have tried several different ways and have not been successful. Just to let you know I am talking about an MSN account (i.e. abcde555@MSN.com) not a hotmail account (abcde@hotmail.com). They use the same website to sign in but you have to input msn.com instead of hotmail.com. I think this might be part of the problem because I believe the phone is trying to access my account as hotmail.com (since that is the site you have to go to to access my email account) when really it is an msn account. If anyone can help me at all I would really appreciate it! Thanks!!!
