Comment 83 for bug 2004480

This is still not working on my Mac or my family member's Mac. When trying to configure for POP3, I get a message that says "You are about to override how Thunderbird identifies this site." The location is set to "outlook.office365.com:995" and it asks me to get a certificate, the certificate lists "outlook.office365.com" but without any ports.

When I try the "Get Certificate" button, it replies "This site attempts to identify itself with invalid information. When I remove the port 995, so the location says "outlook.office365.com" and press the "Get Certificate" button it replies "Valid Certificate, this site provides valid, verified identification. There is no need to add an exception." Except that this point there is only a Cancel button.

If I leave in the port so the location says "outlook.office365.com:995" and press the "Confirm Security Exception" button, it replies "Unknown Identity. the certificate is not trusted because it hasn't been verified as issued by a trusted authority using a secure signature".
