Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
The error AADSTS5000224 indicates that the Microsoft Entra tenant being accessed has been deauthenticated and is currently unavailable. Since you were able to sign in previously and this started unexpectedly today, this may require investigation by Microsoft rather than being a normal sign-in issue.
As a quick check, try signing in from an InPrivate/Incognito browser window and try the following URLs:
-
https://ms.portal.azure.com -
https://portal.azure.com/<tenant-id> -
https://portal.azure.com/<tenant-domain>
If the same error occurs, I recommend contacting Microsoft Support directly: Contact Microsoft customer support | Microsoft Support
One possible workaround is to create a temporary Microsoft 365 tenant using a trial license:
Go to Microsoft 365 Business Plans and Pricing and click Try for free to set up a temporary Microsoft 365 tenant with a trial license.
-Use this new account to sign in to the Microsoft 365 Admin Center and submit a support request on behalf of your primary (locked) account.
-Click Help & Support > then choose Create a support request.
Note: This method doesn't require you to use your new account for your business. Instead, it allows you to create a temporary global administrator account so you can submit a support request, as your original global administrator account is locked out due to issues with authentication. The trial account is free for one month. Be sure to delete it after submitting your support request to avoid any automatic renewals or charges from Microsoft.
