Except the mistake is Microsoft's and is an expired certificate. I'd be more concerned that other browsers just ignored the issue.
seems to be working Normally now with Firefox.
The whole Outlook/MS experience is starting to be More a Pain than its worth!
MS is REALLY loosing the plot big time.
But the problem still remains!!
WARNING: Reducing your local internet security is NEVER the SAFE answer to these types of issues.
Some browsers are letting you in by lowering their security automatically. If you check the OCSP range of the certificate, you will notice that it expired on May 28, 2017. While Firefox is strict when it comes to the information, Chrome and IE are not. Google's Chrome browser allows the connection, but considers the connection as insecure instead, while Firefox blocks it outright. Exactly how Edge or Opera set themselves, I don't know. But don't think that you are just as secure because you are able to connect to a site that has a certificate out of date. I'd say browsers that allow that are less secure.
