Email not working since 15/04/24

Had the same issue since Monday 15th pm... error 0x800ccc1a on a Windows 7 machine using Outlook 2007. I haven't tried it on my Windows 11 machine to verify if it works on that. My gut feeling based on experience and the number of different settings people seem to be experiencing this problem with, and the email clients that are affected, is that this is a MS security certificate issue, not a POP3/SMTP issue or a TLS/SSL issue. As I believe someone has already mentioned somewhere, it could be that the MS certificates necessary for legacy email clients, and possibly Windows 7 itself, have expired. If that is the case then I'm not even certain that new certificates could be issued for software no longer supported but assuming they can be then it would surely have to come from MS themselves. Whatever the issue is I certainly would not advocate changing passwords, POP3/SMTP settings, TLS/SSL settings, port numbers or anything else. It will probably only make the problem worse. This is a problem on the VM side whatever they tell you, whether its of their doing or a MS certificate issue or indeed something else.

I also find it ironic that the verification email from VM that I had to respond to in order to join this forum was delivered to my VM spam folder. Says it all really.
