Adding Our Own Domain Name To Azure Active Directory

Introduction

 
In this article, we are going to learn how to add a custom domain name to Azure Active Directory. Every new Azure AD tenant comes with an initial domain name, like "<yourdomainname>.onmicrosoft.com", and we can’t change or delete our initial domain name, but we can add our organization domain names. Adding the custom domain names helps us to create user names that are under our domain.
 
Step 1
 
In the Azure Portal, Search for Azure Active Directory from the search box and select Azure Active Directory, and then select “Custom domain names”.
