Whenever Windows Live Mail fails to send a message, it will display an error message explaining what's wrong. If you can't work out what it means, click on it to select it, then use right-click to copy it and paste it into your reply here. Someone will be able to tell you what to do once we can see the entire error message.

 This is the message I am getting: (any advise?)
