If you are self-employed and you are the only person managing your Microsoft 365 account, you may need to recover your Global Admin access if you are unable to access the admin center. Here are some steps you can take:
- Confirm Account Details: Make sure you are using the correct email address associated with your Microsoft 365 account.
- Identity Verification: You may need to go through Microsoft's identity verification process. This could involve providing business documentation or verifying domain ownership.
- Submit a Support Request: If you cannot access the admin center, you can submit a support request through the Microsoft 365 support page. Select the option for issues related to account access.
- Contact Microsoft Support: If you are still having trouble, you can try reaching out to Microsoft support via their official support channels. If the phone number you have is not recognized, ensure you are using the correct number for your region.
Since you mentioned that you cannot speak to Microsoft directly, submitting a support request online might be your best option. Make sure to explain your situation clearly, indicating that you are the sole administrator and need to regain access to manage your account.
