Suddenly live mail will not send.  the message shows as sent in the sent box, but it did not get sent.  I have several email accounts and not of them will send. My email provider is EMBARQMAIL    I can send and receive on my ipad and iPhone.  My 2011 will receive.  can send email from my ipad.  I talked with Embarqmail support.  They suggested I do a restore.  I did that back to the 8th and live mail still will not send.  Again, the messages show as sent in the sent box, but in fact they are not sent  I am running windows 10
