I have 2003 and 2 owa servers right now. I'm migrating to 2010, I have 1 server already setup running the hub, Cas and Mailbox roles already. I will in the future probably want to add another exchange 2010 server so that I can have a DAG.
but from what I understand having a second CAS server will not help with load balancing since I don't have a CAS Array. So does that mean all my internal clients will connect to only 1 Cas server and ignore the other even though I have 2 Cas servers available?
Also will all incoming/outgoing email go to only 1 Cas server and not the other.
As for the San certificate, if i have 2 exchange 2010 servers would I need to have all the info for both like below:
CAS1 server FQDN
CAS1 server name
