We have an Exchange 2013 single server that services internal and external clients. All was working correctly until we had to renew the SSL cert and with a new Godaddy cert that could not have any “local” SANs (exchange.domain.local).
I reconfigured the AutoDiscoverServiceInternalUri, EWS (Default Web Site)” -InternalUrl , and changed the URL for the OAB. I set them to the name on the certificate (mail.domain.com)and can ping that name from the inside. All the internal Outlook clients
get an error “Problem with the proxy server’s security certificate. The name on the security certificate is invalid or does not match. (Error code 10). OWA works just fine and the remote clients are not having an issue
What do I need to reconfigure?
