Exchange 2013 Cert warning when connecting to CAS server

I am currently migrating from exchange 2010 to 2013 I have all the servers set up 2 mailbox and 2 CAS along with my 2010 2 mailbox and 2 CAS.  There is a load balancer in-front of the 2013 server but when I switch the autodiscover DNS entry to the load balancer when a user opens outlook I am getting a cert warning the server is coming up servername.domain.local instead of mail.domain.com which is the certs primary domain.  All the 2013 virtual directories as well as the load balancer is in the mail.domain.com form what am I missing I understood you didnt need to and shouldnt have the local servers name on the SSL cert.  Any Ideas?

Also the only thing I can find different all the 2013 components OWA, OAB, ECP etc point to mail.domain.com but the autodiscover  there seems to be two for the 2010 server and for the 2013.  I have been changing the autodiscover.domain.com to point to the load balancer which outlook then throws the error.  It the below correct?EX2013

I believe you may have to also add the cert to the load balancer if you haven't done so already.

Yes but they do not include local server name just mail.domain.com, autodiscover, mx etc

IS this correct?EXCASAuto
timgreen7077Exchange EngineerCommented:
yes that is fine, but I would have made the autodiscover SCP match the 2010 also, but it really doesnt matter. you should have your internal DNS pointing to the new autodiscover record and that record should be pointing to the virtual IP of your load balancer.

I was just pointing autodiscover.domain.com to the IP of the load balancer did I miss a step?
timgreen7077Exchange EngineerCommented:
you need to point the autodiscover record for your 2013 servers to the load balancer, not the 2010 autodiscover.
