IIRC, the OP had to change their internal OWA URL to their CAS name while keeping the external URL the OWA FQDN. Not sure why that worked, since we've tested extensively with a single namespace for OWA and it works fine.
If you run a "Get-ExchangeCertificate | fl" in PowerShell, does the cert you have assigned to IIS show up as valid?
