Unable to send emails Error: Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity

I am having problems with my Windows Live Mail even before I upgraded to Windows 10. I am receiving messages but they won't always go out. Right now I am getting a message that says "Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity."

Just as I started to type this, the graphics and words in live mail were all distorted. Also a box saying 'purging' comes up but it never seems to do anything.

The people I have internet service with tried to help by making an e-mail with a 1 as default and that seemed to help for a while.
