The MX record that you add includes a value (the Points to address value) that looks something like this: <MX token>.mail.protection.outlook.com, where <MX token> is a value like MSxxxxxxx.

  1. On your DNS host’s website, click to add a new MX record.
  2. Now you get the information using Locate Your Unique DNS Values in Office 365. For the MX record copy, the Points to address value. You will use this value in the record you are creating on your DNS host's site, as described in the next step.
