Before you set up your domain with %BRAND_OFFICE_365_SHORT%, we have to make sure that you own the domain name. To do that, you'll add a specific record to the DNS records at your DNS hosting provider. We then look for the record to confirm ownership.

Note: This doesn't affect how your domain works.
