I keep getting " unknown error has occurred" when I try to delete some emails from my Inbox (Windows Mail 2012).  I try moving them to the delete folder but unable to do so.  I have tried to " Repair all Windows Essentials Programs" to no avail.  What can I do to delete these emails?   I have no  problems deleting emails when I  am on Bell Mail internet but cannot delete from Windows Mail.  Any ideas??
