What is a domain name?

A domain is a unique name that appears after the @ sign in email addresses, and after www. in web addresses. It typically takes the form of your organization's name and a standard Internet suffix, such as yourbusiness.com or stateuniversity.edu.

Using a custom domain like "rob@contoso.com" with Office 365 can help build credibility and recognition for your brand.

You can buy a domain in Office 365 and we'll set it up automatically, or you can buy or bring one you already own from a domain registrar.
