Exchange 2007 / 2010 Backpressure – Quick Fix Awarded Article by Alan Hardisty On 2011-12-21 exchange 2010 Views: 38,193 66,503 Points What is Backpressure? Backpressure is a new ‘feature’ in Exchange 2007 / 2010 where Exchange actually monitors resources such as Free Disk Space on the disk where the Exchange Message Queue / Message Queue Transaction Logs live and the Memory that the Edgetransport.exe process is using and memory in general used by other processes. How do I know if my server is suffering from Backpressure? event id 15006 If one or more items being monitored hits a pre-defined limit, then Exchange will stop inbound mail-flow, so usually the first thing that you notice is that all of a sudden, you are not receiving emails from the rest of the world. You will be able to continue to send emails, you just won’t receive any new emails. 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.

In this article: An overview of Transport service resource monitoring Customizing back pressure thresholds Detecting back pressure Monitoring Transport queues Monitoring event logs Monitoring protocol logs Microsoft Exchange Transport Service Resource Monitoring Back pressure is the name for a condition that an Edge Transport or Hub Transport server is in when it is in an overloaded state and is actively refusing some or all further connection attempts from other systems. The overloaded state is based on a series of resource utilization metrics: Free disk space on the drive(s) that store the message queue database and logs Uncommitted queue database transactions in memory Memory utilization by the EdgeTransport.exe process (the Microsoft Exchange Transport service) Overall memory utilization for the server Each of those metrics is measured individually, and as such each is individually capable of causing the server to go into a back pressure state. There are two different levels of back pressure. as well as the condition where no over-utilization is occurring, so in total there are three resource utilization conditions that your Edge or Hub Transport servers can be in: Normal - all is well and the server is performing its role as intended (assuming you
