Unable to delete orphaned Entra ID tenant created by myself – lost admin permissions

I created an Azure / Entra ID tenant around 2 years ago using my organization’s corporate email address for internal testing purposes.

Now I am trying to permanently delete this tenant because it is causing constant conflicts with Microsoft Teams and authentication flows. However, I discovered that my account no longer has Global Administrator permissions, even though I was the original creator of the tenant.

At this point:

• My account appears only as “Member”
• I cannot leave the organization because it is marked as my home tenant
• I cannot assign roles
• I cannot delete users
• I cannot delete the tenant
• There are no visible administrators in the tenant

I have already tried multiple recovery approaches:

• Associating the tenant with subscriptions
• Accessing through Entra Admin Center
• Microsoft 365 Admin Center
• Azure Portal
• Attempting to recover administrative access
• Reviewing tenant deletion requirements

According to Microsoft documentation, the only apparent recovery option is taking ownership of the domain again, but that does not solve my actual problem.

I do NOT want to recover or manage this tenant anymore. I simply want to permanently remove/delete the orphaned tenant that I originally created.

Honestly, it is extremely frustrating that a tenant created by myself can become impossible to remove and continue causing authentication and Teams conflicts years later.

Has anyone experienced this situation before? Is there any supported way to:

• force-delete the tenant,
• remove my account from the tenant,
• or completely detach my corporate email from this orphaned Entra ID organization?

Any urgent help would be greatly appreciated.
