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.
If you're unable to create Azure AD or Azure AD B2C tenant, review your user settings page to ensure that tenant creation isn't switched off. If tenant creation is switched off, ask your Global Administrator to assign you a Tenant Creator role.
To create a new tenant
Sign in to your organization's Azure portal.
From the Azure portal menu, select Azure Active Directory.
On the overview page, select Manage tenants
On the Basics tab, select the type of tenant you want to create, either Azure Active Directory or Azure Active Directory (B2C).
Select Next: Configuration to move on to the Configuration tab.
On the Configuration tab, enter the following information:
Type your desired Organization name (for example Contoso Organization) into the Organization name box.
Type your desired Initial domain name (for example Contosoorg) into the Initial domain name box.
Select your desired Country/Region or leave the United States option in the Country or region box.
Select Next: Review + Create. Review the information you entered and if the information is correct, select create.
Your new tenant is created with the domain contoso.onmicrosoft.com.
Your user account in the new tenant
When you create a new Azure AD tenant, you become the first user of that tenant. As the first user, you're automatically assigned the Global Administrator role. Check out your user account by navigating to the Users page.
Ensure your directory has at least two accounts with global administrator privileges assigned to them. This will help in the case that one global administrator is locked out. For more detail see the article, Manage emergency access accounts in Azure AD.
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're signed in to the directory that you want to delete through the Directory + subscription filter in the Azure portal. Switch 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 are deleted.
