Mostly, this issue originates server-side due to the security certificate presented by the specific server, Windows Live Mail, mismatching the URL being used for connection. In some instances, though, the problem could also stem from glitches or problems on the client’s end. Here are some of the most efficient solutions that you could implement to resolve this issue:
Solution 1: Wait out the storm
Server-side hiccups are the most common cause of this problem, and if the cause is server-side, the problem is almost certainly going to be temporary.

That being the case, making sure that Internet Explorer is not set to work offline is definitely worth a shot. In order to do so, you need to:
