How do I create an MX record in Microsoft DNS?

From the MX row in the Exchange Online section of the Add DNS records page in Microsoft, copy the value listed under Points to address. You’ll use this value in the record you’re creating in this task. On the DNS Manager page for the domain, go to Action > Mail Exchanger (MX).

Do MX records need a period at the end?

What this means is that CNAME/MX/NS records (anything where the “target” is a hostname) must end with a “.” to indicate that it is a FQDN. The exception to this is that if it is simply a “short name” (i.e. no dots) then DNSControl will add the domain to it.

Do DNS records expire?

DNS propagation can be thought of as the time it takes DNS records to expire on a server. For example, if you update your nameservers to point to a different hosting company, those new nameservers must propagate across the Internet.

What happens if domain does not have MX record?
