Enforcement Sensor Status

NOTE: If Graph API Enforcement is enabled in your organization, Enforcement Sensor Status is redundant and not visible on the Sensor page.

When enforcement has been enabled for a sensor, the enforcement status is listed on the Manage > Sensors page for that sensor:

Successful enforcement status for the sensor.
Successful enforcement status for the sensor

The combination of these 2 states are reflected in the tab for the sensor.

Cloud Email Protection may report the status "Errors with enforcement actions:"

Enforcement status errors.
Enforcement status errors

The "Errors with Enforcement actions" state is defined as:

Fewer than 80 out of the last 100 messages could be enforced

This state may be shown in the very beginning stages as you are testing enforcement.
