Add Custom Domain Name To Azure Active Directory

The steps to add custom domain name to Azure active directory is very simple. However one has to understand why. Assume that your organization signs up for Intune, a Microsoft cloud-based service. You’re get domain name hosted in Azure Active Directory (AD) that looks like domainname.onmicrosoft.com.

Every Azure AD directory comes with an initial domain name in the form of domainname.onmicrosoft.com. So what if you don’t want to use the default domain and add custom domain ?. Yes, you can add custom domain name to Azure AD. As of now you can add up to a maximum of 900 managed domain names. Most of the organizations use other domain names to build business. In such cases Azure AD allows you to assign user names in the directory that are familiar to your users.

Add Custom Domain Name to Azure Active Directory

Here are the steps to add custom domain name to Azure Active Directory. First of all sign in to the Azure portal with an account that’s a global admin for the directory. In the left pane, click Custom domain names. To add a custom domain click +Add custom domain.

Enter the name of your custom domain in the box, and then select Add Domain.

The next step is to add DNS entry for domain name in domain registrar. Once you add DNS entry, Azure AD can then verify that your organization owns the custom domain name. Sign in to the domain name registrar for the domain. Update the DNS zone file for the domain by adding the DNS entry provided to you by Azure AD. Once the DNS records are propagated, your domain name is ready to get verified. Click Verify to start the process.

Finally on the right pane we see verification succeeded message which means that our custom domain has been verified.
