Ever since Microsoft abandoned Hotmail, Windows Live Mail loses E-mails constantly.  Any attempt to create storage folders and place e-mails there inevitably leads to the error message:  "Message Can't be Found."  I tried the suggestions you previously made.  They did not work.  When I do a search for the E-mails, I find between the backups and the main drive, the E-mails are there - in the folders where they were.  However, Windows Live can't find them to open them.

I tried exporting them to an empty folder on the desktop, and I see long minutes of moving files.  However, when I open that folder, there are just a lot of empty folders.

Any ideas would be helpful.
