Delete Microsoft 365 Tenant

There are various reasons why you may need to delete a Microsoft 365 tenant. The most common one I run into is after a corporate merger or acquisition. In this post, I will show step-by-step how to delete a Microsoft 365 tenant.

Prerequisites

• All invoices are paid
• All domains are removed other than the CompanyName.onmicrosoft.com domain name
• All users are deleted and deleted from deleted users except for one Global Admin.
• All App registration and Enterprise applications are deleted.
• No Azure subscriptions.
• All licenses are deleted and removed.

Completing all of those perquisites will take time and sometimes things are stuck but it is possible to complete all of them.

The Process

• Login to Entra admin center
• Click on Identity > Overview

• Click on Manage tenants

• Select the tenant and click Delete

• It will check if the tenant can be deleted.

• If all checks pass you can click on Delete.

• After clicking Delete you will see a notification letting you know the tenant has been deleted.

• Once you log out that is the end.

If you try to log in again you will get errors.

That’s all it takes to delete a Microsoft 365 tenant.
