I recently created a new SSL Certificate and self-signed it via this tutorial.
The new certificate showed up in the list of certificates. I then assigned IMAP, POP, SMTP & IIS to the certificate. This switched the certificate on the IIS bindings for port 443 to the newly created certificate. The problem is, when I use my newly created certificate, then I try to access OWA, I get "Connection Reset" on FireFox. When I switch back to the old certificate, via bindings in IIS, it works fine.
The only difference is the SSL certificate. What could cause this?
