Since I installed the version 1511 Windows 10 Professional 64 bits and the build 16.4.3563.0918 of Windows Live Mail 2012, I keep receiving a message when Windows Live Mail tries to access some servers for the reception of some of my email adresses (not all of them.)

On my other pc which still run on the previous build of Windows Live Mail, also with Windows 10 version 511 but not professional, I don't have theses messages, so that means that the issue is probably due to the 16.4.3563.0918 build of Windows Live Mail 2012.

The message says :

The server you are connected to is using a security certificate that cannot be verified.

The signature of the certificate cannot be verified

Of course I have already tried a  number of solutions (repair, etc...) but none has worked so far.

Any help will be welcome.
