Power BI Refresh Error:
TeamsAppBlockedInTenant
What does this error mean?
A Fabric Activator rule configured to send Teams alerts cannot deliver messages because the Fabric Activator Teams app has been blocked by a Teams administrator at the tenant level. All Activator-to-Teams notifications are silently dropped until the app is unblocked.
Common causes
- 1The Microsoft Teams administrator blocked or did not allow the Fabric Activator app in the Teams Admin Center
- 2A tenant-wide policy requires admin approval for third-party or Microsoft apps before they can be used
- 3The Activator Teams app was previously allowed but was later blocked as part of a Teams governance review
How to fix it
- 1Ask your Microsoft Teams administrator to check the Teams Admin Center under Manage apps > Fabric Activator
- 2The admin should change the app's status from 'Blocked' to 'Allowed' for the tenant
- 3As a workaround while waiting for admin action, switch the Activator rule's alert delivery from Teams to email
Beyond the docs
Common practitioner solutions not covered in the official documentation.
- 1If your organization uses app permission policies, ensure the Fabric Activator app is included in the allowed list for the relevant users
