Verify your domain
Choose Settings, then Domains in the Office 365 Admin center. (Be sure to sign in to Office 365 first.)
In the domains section, click Add domain to start the wizard.
Add the domain you want to use, and click Next.
Follow the steps in the wizard to add the record that verifies to Office 365 that you own the domain. You can also follow the link to step-by-step instructions for your registrar if you get stuck. Click Verify to continue.
Set up services automatically
To finish, you have to update some records at your DNS host or domain registrar. You can either use NS records and have Office 365 automatically set up the correct DNS records, or you can do it manually.
The wizard typically detects your registrar and gives you a link to step-by-step instructions for updating your NS records at the registrar website. If it doesn't, follow these general steps for changing NS records.
Office 365 will automatically set up email and other services for you.
