SSL certificate expired but system works just fine!

Honored experts.

Im running an old Small Business Server 2011.
I have just been made aware that my SSL certificate from Godaddy.com expired more than 4 weeks ago.
HOWEVER everything is up an running?
Local Outlook clients, external Outlook clients, Iphones.
I expected all this to go down when the certificate expired.
Can anyone explain this?

Certificates in this current situation, is for the client to have a piece of mind that the line is secure.
This is not an enforced policy though (drop lines if cert is expired). It's not that bad either, as all the clients in this case aren't customers, but your own colleagues/employees. Also, the communication is actually still encrypted.
The most probably thing that happens is a warning (in this case, all the clients you used didn't display this warning). The least probable thing that happens is no warning.
Local Outlook don't need this certificate anyway. External Outlook through VPN don't need it either. An Outlook Anywhere configuration DOES need it.
All in all, it's how the app warns you that is the most you can hope for.
Luckily, when browsing to a site where you have to pay, your browser will warn you (or at least, the best browsers will).
