FQDN of Exchange CAS servers not in SSL cert

I have a client that does not own the Domain Name of the internal AD Domain. So we had to remove the FQDNs of the CAS servers while retaining mail, Legacy, and autodiscover. What are the potential issues by not including the internal CAS FQDNs in the cert?

Thanks

That depends :)

What FQDN do end-users, both internal and external, connect to when they access the Client Access Servers?

To add to Andy...if you cannot put the internal names in the cert, then you will have to implement split DNS (if you haven't already done so). This means creating an internal DNS zone for your external namespace. In the inside network, the FQDNs resolve to an internal address of the CAS and on the internet, the same fqdns will resolve to public IPs. You will have to set both the InternalURL and ExternalURL paramenters for each of the CAS virtual directories to the external fqdn name. This will usually be your owa.domain.com address. Also include autodiscover.domain.com in your cert and you should be set.

Again, all this depends on your overall architecture and design. But you can get away with not including the internal CAS server names in your cert.
