Add a domain to Microsoft 365


Follow these steps to add, set up, or continue setting up a domain.

To Add, modify or remove domains you must be a Global Administrator. If you do not have Global Admin then please contact Support directly. These changes affect the whole tenant, Customized administrators or regular users won't be able to make these changes.


  1. Go to the admin center at
  1. Go to the Setup > Domains page.

  2. Select Add domain.

  3. Enter the name of the domain you want to add, then select Next.

  4. Choose how you want to verify that you own the domain.

  5. Choose how you want to make the DNS changes required for Office to use your domain.

    1. Choose Add the DNS records for me if you want Office to configure your DNS automatically. This is not recommended as we do not have full control of the Zone File.

    2. Choose I'll add the DNS records myself if you want to attach only specific Office 365 services to your domain or if you want to skip this for now and do this later. This is recommended as we are better positioned to provide Support when we manage the Zone File.

  6. If you chose to add DNS records yourself , select Next and you'll see a page with all the records that you need to add to your registrars website to set up your domain.


  7. Select Finish - you're done!
