Help ...below is the message I receive when I attempt to send out email from live mail. Incoming works perfectly. I contacted the company Windstream that does my email and they claim the problem is with live mail. It appears that all my settings are correct and this problem is not a windows 10 problem since it also occurred with windows 7 prior to my update to 10. I have changed the port numbers twice on Windstreams suggestion from 25 to 587 and that does not fix. Windstream claims if I go to their website I will be able to send emails there. My question is why can I send gmail with no problem and why does this email not send.
Any advice would be much appreciated.
