I am using Windows Live Mail and Hotmail.  After reading emails in my inbox I move any unwanted ones to the deleted mail box. I then try to empty this box and initially it shows as empty.  However if I then shut down my email connection and then reopen, some of the emails have returned, either to my inbox or to the deleted email box.  Only the heading of the email has reappeared, there is no text, and there is a message to tell me that the message has not been received.   How can I fix this?
