The Microsoft® Exchange Server Analyzer Tool sends a test message to a user-defined external recipient SMTP address from the server that is running Exchange Server. The Exchange Server Analyzer then scans the message tracking logs of the server to determine whether any issues were found with the delivery of the test message.

As a part of this scan, the Exchange Server Analyzer queries the EntryType property for the Exchange_MessageTrackingEntry Microsoft Windows® Management Instrumentation (WMI) class under the root\MicrosoftExchangeV2 namespace to determine why one or more message tracking log entries were created.

The Exchange Server Analyzer displays an error if the following conditions are true:

This error may indicate that the test message is still in one of the Simple Mail Transfer Protocol (SMTP) remote Delivery queues for the sending server and there is an issue with the queue.

A remote Delivery queue holds messages that are destined for remote delivery. The name of the queue matches the remote delivery destination. This destination may be a connector, a server, or a domain.

To troubleshoot protocol errors, increase diagnostic logging for the MSExchangeTransport service for the SMTP component, and review the logs for errors. Alternatively, you can use the Network Monitor (Netmon.exe) tool to obtain information about network connection errors. To reproduce the problem, you may have to force the queue to try again. Examine the event log for possible errors associated with the Microsoft Exchange Information Store service.

For more information about how to modify logging settings, see "How to Modify Logging Settings for MSExchangeTransport" in the "Troubleshooting Mail Flow and SMTP" section of the Exchange Server Transport and Routing Guide (http://go.microsoft.com/fwlink/?LinkId=47579).
