Hello all and thank you in advance for taking the time to answer my question.
I have 2 Exchange 2010 servers in the same forest, different locations, different IP's, different domains. Exchange 1 is primary Exchange 2 is secondary.
mx and dns records points to ex1mail.exchange.com IP , ex2mail.exchange .com IP.
I need to purchase a SAN SSL Cert where ex1mail.exchange.com is primary and ex2mail.exchange.com is secondary.
iPhone and OWA users can connect to both sites using either dns now but ex2mail.exchange.com gives a cert error since I have not purchased and installed it yet.
My question is: If Exchange 1 becomes unavaiable (internet drops) will the outside users (mainly iPhones) automatically failover to the secondary Exchange activesync site on the SSL cert.
