I have two Exchange 2010 servers in a CAS array (single site) The FQDN for the CAS Array is cas.mydomain.com. Users get to OWA using mail.mydomain.com
I'm using a third party UCC cert and on that cert, I have autodiscover.mydomain.com, mail.mydomain.com, legacy.mydomain.com. I do not have the CAS Array name on the certificate, nor do I have the server hostnames on the cert.
For DNS:
external DNS, mail.mydomain.com points to our public IP
Internal DNS, mail.mydomain.com points to the VIP of my hardware load balancer
For Set-ClientAccessServer, I have this
AutoDiscoverServiceInternalUri : https://mail.mydomain.com/autodiscover/autodiscover.xml
For OWA, ECP, ActiveSync, EWS and OAB....I have the internal URLs set to mail.mydomain.com
Is this incorrect? I did it this way since I do not have the cas array fqdn on my UCC cert.
Thanks,
