Thank you for your question. When you delete your default Entra (Azure AD) tenant, you lose access to both the Azure portal and its support systems, which depend on that tenant for identity and permissions. Unfortunately, this means you cannot submit support tickets as your identity is no longer recognized by Azure.
Here’s what you can do:
If you have access through a different tenant (or a separate subscription not tied to the deleted tenant), try logging in with those credentials to regain support portal access.
Alternatively, reach out to Microsoft Azure support directly via their public channels (such as the Azure Support Twitter account or Microsoft’s support phone lines) and explain the situation. Provide your subscription ID, email address, and details about the deleted tenant—they may be able to escalate your request to restore account access or advise on possible next steps.
In the future, always ensure you have a backup global admin account or a second tenant owner before deleting a tenant to avoid accidental lockouts.
Best regards,
Jerald Felix
