I'm migrating an Exchange 2003 organization to Exchange 2010. The 2010 includes a CAS array. We are using split DNS to avoid certificate issues next year. The domain name (inside and outside) is contoso.com. The CAS array name is CAS. FQDN for OWA and ActiveSync is webmail.contoso.com
I know I need webmail.contoso.com and autodiscover.contoso.com on the certificate. My question is what name do I need on the certificate for the CAS array? CAS.contoso.com? Are there any names I am over looking for the certificate?
