Quickstart: Create a new tenant in Azure Active Directory
You can do all of your administrative tasks using the Azure Active Directory (Azure AD) portal, including creating a new tenant for your organization.
In this quickstart, you'll learn how to get to the Azure portal and Azure Active Directory, and you'll learn how to create a basic tenant for your organization.
If you don't have an Azure subscription, create a free account before you begin.
Create a new tenant for your organization
After you sign in to the Azure portal, you can create a new tenant for your organization. Your new tenant represents your organization and helps you to manage a specific instance of Microsoft cloud services for your internal and external users.
To create a new tenant
Sign in to your organization's Azure portal.
From the Azure portal menu, select Create a resource.
Select Identity, and then select Azure Active Directory.
The Create directory page appears.
On the Create directory page, enter the following information:
Type Contoso into the Organization name box.
Type Contoso into the Initial domain name box.
Leave the United States option in the Country or region box.
Your new tenant is created with the domain contoso.onmicrosoft.com.
Clean up resources
If you're not going to continue to use this application, you can delete the tenant using the following steps:
Ensure that you are signed in to the directory that you want to delete through the Directory + subscription filter in the Azure Portal, and switching to the target directory if needed.
Select Azure Active Directory, and then on the Contoso - Overview page, select Delete directory.
The tenant and its associated information is deleted.
