If you already own a domain name, you can add the domain to your Microsoft Office 365 for professionals and small businesses account. This topic describes the necessary steps for adding your domain name to Office 365 after Office 365 has verified that you own the domain, so that you can use the domain with Office 365.
|If you’re moving a domain from Office Live Small Business, do not follow the instructions here. Instead, see the information at the Office Live Small Business to Office 365 Transition Center.|
To finish adding the domain, you change the domain’s name server (NS) records on your domain registrar to the Office 365 primary and secondary name servers. Alternatively, if you’re comfortable with DNS management and you want to set up and manage your Office 365 DNS records yourself, see Add your domain to Office 365 but continue to manage your domain's DNS records. For more information about adding your domain to Office 365, see Options for adding your domain to Office 365.
When you change your domain’s NS records to point to Office 365, all of the services that are currently associated with your domain—for example email, websites, blogs, and shopping carts—are affected. If you’re using your domain for any of these services, make sure you take the necessary steps to ensure that this transition does not result in downtime for the services.|
If you don’t take the necessary additional steps, your users might lose their email access and your current website might be inaccessible. For more information, see Update DNS records to keep your website with your current hosting provider.
