Frequently Asked Questions

What does Microsoft 365 error AADSTS7000112 mean?

Error AADSTS7000112 means that an application's service principal (its identity within your organization) has been disabled in the Microsoft Entra ID (formerly Azure AD) tenant. As a result, users are blocked from signing into the application using their Microsoft credentials.

Can I fix error AADSTS7000112 myself as a standard user?

No. Standard users do not have the necessary permissions to modify application access policies. You must contact your IT department or a Microsoft 365 global administrator to re-enable the application.

Why can the Fathom bot still join my Zoom meetings if the app is disabled?

The Fathom bot's ability to join meetings often operates independently via Zoom API integrations or scheduled webhooks. However, error AADSTS7000112 specifically blocks the interactive user sign-in process required to access the dashboard and view the saved notes.

How long does it take for the fix to apply once the admin enables the app?

Once the Microsoft 365 administrator sets 'Enabled for users to sign-in?' to 'Yes' in Microsoft Entra ID, the change is usually effective immediately, though it may take a few minutes for the token cache to clear across all Microsoft services.
