I use to have my msn.com account linked up with my Mac mail, but just recently I can't get mail to work with a msn.com account. Is there something new I can do or try to get this feature working again.
First check in Mail's Menu item "Window" and select 'Connection Doctor'. Use that to check at what part the connection is failing and then you can self correct the problem. Plus check the MSN web account to see if they changed anything.
