UCC for multi-location, multi-server Exchange 2010 environment
We are planning to implement a new Exchange 2010 environment that will consist of two offices (e.g. New York and Washington DC) with two HUB/CAS servers and two Mailbox servers at each location. Now we are trying to determine the names to include on the UCC certificate. Assume the internal domain name is abc.local and the external domain name is abc.com. Below is a list of names to include on the UCC.
mail.abc.com (common name used for OWA, IMAP/POP3/SMTP and Exchange ActiveSync)
autodiscover.abc.com
DC Hub and CAS server internal addresses
DCHUBCAS001.abc.local
DCHUBCAS002.abc.local
DC mailbox server internal addresses
DCMBX01.abc.local
DCMBX02.abc.local
NY Hub and CAS server internal addresses
NYHUBCAS001.abc.local
NYHUBCAS002.abc.local
NY mailbox server internal addresses
NYMBX01.abc.local
NYMBX02.abc.local
DC Hub and CAS server internal addresses
DCHUBCAS001
DCHUBCAS002
DC mailbox server internal addresses
DCMBX01
DCMBX02
NY Hub and CAS server internal addresses
NYHUBCAS001
NYHUBCAS002
NY mailbox server internal addresses
NYMBX01
NYMBX02
First, I want to know if I am missing any names?
Second, do I need a UCC certificate on the mailbox servers?
Third, I want to know if I can use just one UCC for all my Exchange servers or if I will have to get a different UCC certificate for each location/server? Are we able to use just mail.abc.com for OWA, IMAP/POP3/SMTP and Exchange ActiveSync even though users based in New York will need to be directed to one of the New York HUB/CAS servers and DC users will need to be directed to one of the DC HUB/CAS servers? I have read that some clients/devices will have problems if the common name does not match the name used by the client/device. If this is the case, will I need to create a UCC certificate with a common name of nymail.abc.com and dcmail.abc.com or nymail1.abc.com, nymail2.abc.com, dcmail1.abc.com and dcmail2.abc.com?

I am accepting 5g6tdcv4's comment as the best solution with full points as I think it will be the best solution in most situations but due to the fact that this solution did not work in our environment I also accepted my own solution which resolved the issue for us.
