On my desktop PC, I use Windows Live Mail 2012 on Windows 7.  In Quick View that displays my unread messages, there are two message headers that I read earlier on my laptop and deleted.  The message headers still appear in my desktop PC with a red line strikethrough as unread.  The message body displays "Message is no longer available on the server. Windows Live Mail is unable to retrieve the requested message because the server no longer has the message available."

The delete X is grayed out and unavailable. How can I delete these two message headers?
