Introduction
In this post, we are going to see how to add a custom domain name in the Azure Active Directory (Azure AD) and how to set it as the primary Active Directory
The Azure AD tenant should come with a username.onmicrosoft.com initial domain.
By adding our own custom domain for our company, we can use it for company purposes such as user authentication (for example, if we add the custom domain name, we can create a user under the active directory such as [email protected]).
How to add a custom domain as an active directory in Azure AD
Click + Add Custom Domain
On the right side, you should see the option to add the domain. In that custom domain name, add your domain name (for example, azure.contoso.org)
After adding the domain you can add the record sets for verifying the added domain. Copy the TXT record in the Destination or that points to the address text box
Go to your Domain Register (Go-Daddy or Azure DNS) vendor website and paste the copied TXT record in the record set creation area. (For example, I have added to AWS Route 53)
After adding the record set, you can see that the record set has been saved in your Domain registered website
After adding the MX record in your registrar -> click Verify. Azure will verify that the MX record for our custom domain is available or not.
If Verification has completed successfully you can see the below screen will get the notification under the bell icon.
If you want to make it your primary directory, click 'Make Primary'
Click 'Yes' to make it your primary
Now you can see the domain name under the Custom Domains Tenant
