Create MX records for email flow in Office 365

To direct all the incoming email for your domain to Office 365, you have to create a specific mail exchange record (MX record) at your domain's DNS hosting service.

We provide step-by-step instructions for creating MX records and other DNS records at many popular DNS hosting providers.

If you have more than one MX record for your domain, make sure the MX record used for email flow has the highest priority.
