Original Title: Windows Live Mail Help

This may be a bit difficult to describe, so please bear with me. I'm having trouble with WLM. There are messages in my inbox that I am unable to delete. I can't open them and a line appears through the Subject and Sender, as well as a red X on the envelope icon. In addition, I often get a message indicating the email message is "No longer on the server." 

Any help would be greatly appreciated.
