If you already own a domain name, you can configure it to work with your Microsoft Azure AD tenant. After you configure your domain to work with Azure AD, you can change the destination of domain services—such as email and web hosting—to point to your cloud service.
If you already have a domain registered with a domain name registrar, and you want to configure it to work with Azure AD, domain verification is required to confirm that you own the domain. To verify your domain, you create a DNS record at the domain name registrar, or wherever your DNS is hosted, and then Azure AD uses that record to confirm that you own the domain.
For detailed instructions on how to create a DNS record at various domain name registrars, see Create DNS records for Office 365 when you manage your DNS records.
