Look in your event logs and if Backpressure is being applied, you will see Event ID's 15006 or 15007 in the logs: Event log entry for critically low available disk space Event Type: Error Event Source: MSExchangeTransport Event Category: Resource Manager Event ID: 15006 Description: The Microsoft Exchange Transport service is rejecting messages because available disk space is below the configured threshold.
