I can no longer delete anything in Windows Live Mail. I can't delete messages that I've read. I can't empty the 'Deleted', 'Sent', or 'Junk' folders.  I can't delete a storage folder that I am no longer using.  I simply can't delete anything.

I have removed and then re-installed my email account[s]. That didn't help.

I completely uninstalled Windows Live Mail and then reinstalled it and that didn't help.

I tried 'restoring my computer' back to a point in which I knew that Windows Live Mail was working correctly, and that didn't help.

Help!   Thank you.
