Hello Dominick Strippoli,
Thank you for providing the error details.
The error code AADSTS5000224 and the message stating that the tenant has been deauthenticated indicate a tenant-level access issue. This cannot be resolved through standard password, MFA, browser, or device troubleshooting.
You will need to contact Microsoft Support and request assistance from the Data Protection Team. This team has the authority and the specific security procedures required to verify your identity as the legitimate owner or authorized representative of the tenant and review whether access can be restored.
Please use the following Microsoft page to find the customer service number for your country or region: Customer service phone numbers - Microsoft Support
Here are some tips and an example of a prompt to help you navigate the IVR more effectively:
When you call the support number, you may hear an introduction of about 30 seconds such as "you can visit the link...". You can ignore this introduction and wait until you are presented with the options. Then press "1" as a business email user, and again "1" for technical help
During the call, you will be asked to provide information that verifies your identity and proves ownership of the tenant, such as your organization name, billing information, contact email, phone number, or other subscription‑related details.
I also recommend calling during business hours. In my experience, it can be difficult to get through to the correct support queue, and automated systems don't always work as expected. If you can't get through on your first try, I suggest trying again later or at a different time.
If you are unable to reach support via the phone numbers, there is a workaround you might consider: You can register for a new Microsoft 365 tenant by signing up for a trial subscription here: Microsoft 365 Business Plans and Pricing | Microsoft 365
Once the new tenant is created, you can access the admin center and submit a support ticket from there, requesting to speak with the Data Protection Team on behalf of your original tenant.
When opening a support ticket, please make sure the Support Assistant (AI) in the Help panel is turned Off. Several customers have reported that the Contact Support option may not appear while the Support Assistant is enabled. Once the AI assistant is turned off, you should be able to enter a description of the issue and the Contact Support option will appear, allowing you to submit a ticket directly to Microsoft Support.
Important notes:
- This new trial tenant will not give you access to any of the data or settings in your original locked tenant. It is solely a temporary means to contact Microsoft support.
- The resolution time might be longer as you are contacting support from a different tenant.
- Remember to cancel the trial subscription for the new tenant once your issue with the original account is resolved to avoid any unintended charges: Cancel your Microsoft business subscription in the Microsoft 365 admin center | Microsoft Learn
