Adding a domain

By default, new tenants' users are given addresses with their tenant name followed by onmicrosoft.com, such as [e-mail]. Adding your own domain, such as contoso.com, means you can change that user format to [e-mail] and have Outlook for Office 365 handle mail for that domain. In this recipe, we'll add the natechamberlain.com domain to our tenant.

Getting ready

You must be a Global Administrator to add a domain. You do not need to have already purchased a domain, as that can be done through this process.

How to do it…

1. Go to the Microsoft 365 admin center at http://admin.microsoft.com.
2. Select Show all > Setup > Domains to add or buy an existing or new domain.
3. For this recipe, we will choose Add domain, but note the option to also purchase your domain if you don't already have one or would just like an additional domain. Select Add domain.
4. Enter your Domain name, then select Use this domain...
