Cannot Access Tenant After Cancelling Signup – Need Help Recovering intandid.onmicrosoft.com

Dear @Marion Campan,

Thank you for posting your question in the Microsoft Q&A forum.

Based on what you described, the custom domain intandid.com has not been added to the tenant intandid.onmicrosoft.com. This usually happens when the signup process was canceled before completion, leaving the tenant in an incomplete state. In this condition, you cannot sign in as an admin or attach your domain because the tenant was never fully provisioned.

When a tenant is incomplete, Microsoft reserves the onmicrosoft name (intandid.onmicrosoft.com) to prevent duplication, but it does not grant you administrative access. Unfortunately, there is no self-service option to recover or finish provisioning that tenant without contacting Microsoft Support for verification.

If you need to start using Microsoft 365 services quickly, the most practical solution is to create a new tenant and then add your custom domain afterward. This method avoids waiting for the original tenant to be released and gets you up and running quickly.

Step 1: Start a new signup process

Go to the Microsoft 365 signup page and create a new tenant using a different onmicrosoft name (for example, intandid-temp.onmicrosoft.com). This ensures you can complete the setup without conflicts. For more information: Compare All Microsoft 365 Plans

Step 2: Complete the signup fully

Make sure you finish the payment and verification steps so that the new tenant is fully provisioned and you have global admin access. This will allow you to manage services without restrictions.

The steps to set up your new subscription vary depending on the Microsoft 365 for business plan that you signed up for. To learn how to set up your new subscription, see one of the following articles:

• Set up Microsoft 365 Business Basic
• Set up Microsoft 365 Business Standard
• Set up Microsoft 365 Business Premium
• Set up Microsoft 365 apps for business

Step 3: Add and verify your custom domain

After the new tenant is active, go to the Microsoft 365 admin center and add your domain. You’ll need to create a DNS TXT record provided by Microsoft to verify ownership. Once verified, you can set intandid.com as the primary domain for email and user sign-in. For reference: Add a domain to Microsoft 365

Step 4: Update user accounts and services

Assign licenses to users under the new tenant and configure email addresses using your custom domain. This ensures your organization branding and mail flow work as expected.

For reference: Add users and assign licenses in Microsoft 365 and Assign or unassign licenses for users in the Microsoft 365 admin center
