I am having this problem. I can't send or receive, and when I close Live Mail, this error message pops up that says that it is downloading message, and it keeps going and going unless I hit the stop tab. The error tab reads like this;

Unable to send or receive from Mikey's Mail account

Server response ERR no such message
