# QueueEmptyingThreshold

Exchange Web Service Connector generates an event when an asynchronous action queue becomes full, becomes empty, or the queue size passes certain thresholds.

This parameter specifies the threshold at which a `QueueEmptying` event is triggered. When the number of actions in a queue falls below this proportion of the total queue size, the event is triggered.

The value of this parameter must be less than the value of QueueFillingThreshold.
