This is in ref. to my previous question on Autodiscover Services.
http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_26469054.html

At that time i was looking to create a SRV record in our external DNS but now we are getting the SAN certificate for our domain.
My question is with the DNS entry of "autodiscover.domain.com" in the SAN certificate, Do I stiil need to create a A record in external DNS for Autodiscover?

In the follwoing post, I see that in case of SAN cert too we need to have a A record in external DNS which will have same IP as Webmail.Domain.com:

Please suggest.

yes of course you do.

you need to point autodiscover.domain.com to your public IP and include the fqdn in the SAN certificate

yes, you need to have name resolution for autodiscover.domain.com and this typically has the same external IP as your owa fqdn
