HI @LemerySHS
If all Global Administrator accounts are receiving the same AADSTS5000224 (TenantDeauthenticated) error, this may indicate that the tenant has been deactivated, restricted, or placed under review. In such cases, Microsoft Support will need to perform additional validation and investigate the tenant status.

As this is a user-to-user community forum and I am just a community member, I do not have access to Microsoft's internal systems or the ability to escalate cases directly to the Microsoft Entra ID engineering team on your behalf.
Therefore, I would recommend that your current administrator contact Microsoft Support by phone and request assistance from the Microsoft Data Protection Team. Please try to find the appropriate hotline number and explain that all administrators and users are affected by AADSTS5000224. Be sure to provide the tenant domain name, Trace ID, Correlation ID, and Timestamp from the error message so that a support ticket can be raised for further investigation.

Kindly let me know when there are updates or if you need further assistance. Any updates you’re able to share would be really helpful.
