*anonymous user* Are you able to delete the subscription from your business store? Or does the error prevent you from performing any actions to delete that subscription?
Recommended Steps:
If you can't delete your Visual studio subscription in the Microsoft 365 admin center, AzureAD admin center or the Azure portal, by following the Delete a tenant in Azure Active Directory documentation. The best course of action, would be to submit a support request.
As you stated above, you don't have any subscriptions on the Azure Portal, but you should still be able to create a support request. You can also use another account/subscription where you can create a support request referencing this issue.
1-Please title the support request similar to your title here "Tenant cannot be deleted" or "Can't delete AzureAD Tenant", etc..
2-Please post your support request number here or feel free to email it to myself or Marilee at:
- AzCommunity@microsoft.com / Title: ATTN James & Marilee - Can't delete AzureAD Tenant
-From there, we can both monitor the issue to make sure our support team driving this forward and once a solution is found we can post it here for the community.
