I am a bit stuck or confused on what my dns records should be for my exchange environment. I have a exchange organisation with 2 MB servers (in DAG) 2 CAS+HT servers and an edge server.
both the CAS+HT Servers are load balanced using barracuda NLB and i have a CAS array as mail.contoso.com (Example) and the mailbox servers are pointing to this CAS Array. I tested creating an account and everything is working fine internally.
Now i installed Edge role in DMZ and i named it edge.contoso.com
Now what will my External DNS Records be. My OWA,OAB,Autodiscover are having mail.contoso.com as external URI.
I was planning these for my external DNS Records :
edge.contoso.com as MX Record
mail.contoso.com as A Record
autodiscover.contoso.com as CNAME Record to mail.contoso.com
Am i in the right direction ? please help. I need to move to production ASAP.
