outlook clients in site A connect to casarray1.domain.com as the exchange server name in outlook's profile.
This is also the name on the exchange cas certificate.
The cas array in site B is casarray2.domain.com
Site B is disaster recovery standby only. If site A fails, I would make a DNS change so that casarray1 points to the ip address of casarray2. Hope that makes sense. I am open to other alternatives.
What I ask is, what name should I have on exchange cas server certificate? casarray1.domain.com or casarray2.domain.com ?
