I use Windows live mail because it groups my mail by "Unread from Contacts".  That is a life saver.  However Windows Live Mail will sit for hours without sending or receiving mail.  The error message of ox80072ee2 comes  up and says failed send and receive.  If I shut my PC down, the mail will probably work at that time.  I seem to have the latest build of 16.4.3528.0331.  I am using a high end PC and Windows 10.  Any suggestions to keep this working?
