You just create A records pointing to 3 servers.<br>That is enough for round robin.<br><br>FYI this is not an automatic failover system'<br>You have to delete one record manually.<br>A L7 loadbalancer will do it for you.

<div>
Thank you I have a question, do I need to change something in the Public DNS not the internal?
</div>


<div>
Please dont change anything in public DNS.<br><br>You cannot use public DNS for DNS RoundRobin as it will take long time for a DNS change to propagate.<br>You need a loadbalancer for that.<br>And you have to use your common name for load balancing.e.g. mail.domain.com

Exchange DNS configuration round robin

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
