In this document we are going to see how to add custom domain name in the azure active directory and make it as primary Active Directory

Azure Active Directory tenant should come with a username.onmicrosoft.com initial domain.

By adding our own custom domain which is used for our company, we can use it for our company purposes like user authentication etc. (for example: - if we added the domain name, we can create a user under active directory like gokulakrishna@azure.contoso.com).

Go to you Domain Register (Go-dady or azure dns) vendor website and paste the copied TX Record in record set creation area. For example: - I have added in AWS Route 53 

After adding the record set, you can see that record set has been saved in your Domain registered website

After adding the MX record in your registrar à click Verify, azure will verify the mx record is our custom domain is available or not.

If Verification completed successfully you can see the below screen and you get the notification under bell icon.
