We have a customer with an SBS 2011 Server, running Exchange (2010) on an ADSL connection with a static IP address and a trusted (GoDaddy issued) SSL certificate.
For some reason, much of the time OWA doesn't work and other times it does. We've tried the big yet simple things:
Reinstalling the SSL Certificate
Replacing the modem
Replacing the network switch
Temporary Disabling the Windows Firewall and Testing
Completely Replacing the SSL Certificate
Disable all non-related sites in IIS (Sharepoint, Client Deployment App, etc).
All with no luck. Internet Explorer just craps out but Google Chrome gives us an SSL connection error which, when we expand for more details, gives us an error code:
Error code: ERR_SSL_PROTOCOL_ERROR
We're at a loss as to how to proceed here.
If we disable 'Require SSL' on the OWA virtual directly in IIS (within the Default Web Site) OWA works fine so the problem is specific to SSL.
Any help would be much appreciated!
