How to find Microsoft 365 MX record
When you register a public domain and verify you own that domain, Microsoft 365 automatically creates a dedicated MX record. The value of the Microsoft 365 MX record is what you need to add to your public DNS for incoming mail flow. In this article, we will show you how to find the value of the Microsoft 365 MX record.

What is the Microsoft 365 MX record value
MX stands for Mail Exchanger and is a type of DNS record that routes emails to specified mail servers. An MX record contains information about the priority and domain name of the mail servers that will handle incoming emails for the domain.
The Microsoft 365 MX record consists of two parts:
- Your registered public domain name.
Note: The dots will be replaced by hyphens.
m365info-com
- Microsoft uses the same static suffix for all domain names hosted in Microsoft 365.
mail.protection.outlook.com
The result is the domain name and the static Microsoft 365 suffix. The MX record will be similar to our example below.
m365info-com.mail.protection.outlook.com
All incoming emails for that domain are routed to Microsoft’s Exchange Online servers for filtering and processing before being delivered to the organization’s Microsoft 365 mailboxes.
Get MX record value from Microsoft 365 portal
You must add the MX record to your domain’s DNS hosting provider. To get the MX record value for your domain, you can find it in Microsoft 365 admin center.
