Using and managing domains in Office 365 Small Business

Office 365 creates a domain for you when you sign up with the services (the domain name includes onmicrosoft.com). But most people would rather use their own custom domain, like fourthcoffee.com, so they’ll have an easy-to-remember email address and website URL for their business. You can add a custom domain now to get started. Or you can do it later, and for now just set up your organization for Office 365, including assigning user licenses and other tasks.

To get started, choose the best fit for your own scenario from the list below.

Note that each of the following procedures requires that you first sign in to the Office 365 portal:
