This article will show you how to create a new Azure AD directory using a custom domain using the Microsoft Azure Portal.
Using a custom login domain, I’ll not going to use the Microsoft Azure default directory UPN which Is [email protected] Instead I’ll use [email protected] as my UPN.
To do this I’ll use the old Azure portal and not the new as this feature Is only available on the old portal.
To start, I’ll Login to the portal https://manage.windowsazure.com -> Active Directory -> New
Directory -> Custom Create
In the Add directory I Select Create new directory and fill In all the details
Next I click on the newly created directory
Next I’ll add a custom domain that will allow me to log on using [email protected]
I Click on Add Domain
In the domain name I type the domain name
Next I will add a TXT record to my DNS zone that will verify the ownership
Once the domain Is verified the status will show Verified
To add users click on users -> Add
As you can see I use my domain now to create login UPN.
When a user try to log for the first time he will need to change his password
