In some cases, you can experience that you can not create the account because your domain is already included in an older Azure tenant, and some minor changes need to be done.
This guide shows you how to remove your domain from an old Azure Portal from previous Microsoft accounts that are no longer active in your domain. This conflicts with setting up an Exchange account on your domain.
- Step 1 - Log in to the old Azure portal
- Step 2 - Open Azure Active Directory
- Step 3 - Go to Custom domain names
- Step 4 - Click the domain you want to remove
- Step 5 - Click Delete
- Step 6 - Done
Note: If you have access to the Azure portal because you bought the products directly from Microsoft, you need to log in to your Azure portal.
Suppose you don't have access to the Azure portal because you bought the subscription with another company (telecom, hosting provider, reseller, etc.), you'll need to contact your old company to ask them to remove your domain from the Azure portal.
Step 1 - Log in to the old Azure portal
Log in to the old Azure portal using your Azure account credentials.
Note: You have to log in using your credentials for your Azure portal and not your one.com Control Panel details.
Step 2 - Open Azure Active Directory
When logged in, search for and open Azure Active Directory in the search bar at the top.
Step 3 - Go to Custom domain names
Click Custom domain names in the menu to the left.
Step 4 - Click the domain you want to remove
In the list, click the domain you want to remove.
Step 5 - Click Delete
Click Delete at the top, and follow the instructions.
Step 6 - Done
That's all. The domain is now removed from the old Azure Portal
Note: It can take 30 minutes until the changes are effective at Microsoft.
