Dear @吉 万,

Based on the information provided, AADSTS5000224 indicates that the Microsoft Entra ID (Azure AD) tenant has been deauthenticated and is no longer available for normal sign-in operations. When this condition occurs, administrators are typically unable to access the Microsoft 365 Admin Center, Microsoft Entra Admin Center, Azure Portal, or OneDrive using standard authentication methods.
Unfortunately, this is a tenant-level backend issue and cannot be resolved through tenant-side administration, password resets, browser troubleshooting, or self-service recovery. Microsoft support intervention is generally required to determine the current state of the tenant and whether recovery options remain available.
Therefore, I recommend opening a support request with Microsoft https://azure.microsoft.com/en-us/support/create-ticketand providing your detailed issue.
Or you can contact Microsoft Support team via phone service number: Customer service phone numbers - Microsoft Support
Please note that as a forum user, I do not have access to tenant backend systems and cannot directly restore access or initiate data exports. If the tenant is still within a recoverable state, only Microsoft support can verify and coordinate the available recovery options.
I hope information about can help you resolve the issue as soon as possible, feel free to reach out if you have any other questions.
