Task: Add a Custom Domain to an Azure AD Tenant

Video: Custom Domains

Estimated time: 20 minutes

Goal

Add a custom domain to your Azure AD tenant and provision a new user with the custom domain name.

Pre-requisites

  1. Azure Subscription
  2. Azure AD Tenant
  3. Publicly registered DNS domain*

*Note: The verification process requires a publicly accessible DNS domain. If you do not have one, you can create a DNS zone in Azure. However, unless you register it, you will not be able to verify the domain and will not be able to provision or test a user with that domain. There are many registrars that will register a domain name for less than $10 US for a year.

Requirements

  1. Configure an Azure AD tenant to use a custom DNS zone
  2. Provision a new user in the Azure AD tenant
  3. Test connectivity for the new user

Pre-requisite: Provision an Azure DNS Zone

You will need a publicly registered DNS zone that you have administrative access to. Azure will require you to create a custom txt or mx record in your DNS zone to prove ownership of the domain. If you do not have access to a DNS domain you can provision a new Azure DNS zone. The name of the zone does not matter. This zone will host your custom Azure AD domain name. You will not be able to complete requirements 2 and 3 unless you register the domain name with an internet registrar.

Requirement 1: Configure the Custom DNS domain in your Azure AD tenant

Register your custom DNS domain with your Azure AD tenant. Follow the instructions during the process.

Requirement 2: Provision a user with the custom domain name

Add a standard user named tasks to the Azure AD tenant using the custom DNS domain that you registered (tasks@yourdomain). Record the password that is generated for the user.

Requirement 3: Test connectivity for the new user

Open a different browser (or private/incognito window) and login to https://myapps.microsoft.com as your task user (tasks@yourdomain). Reset the password to something you will remember.
