To diagnose a problem more indepth, we will use the Exchange Troubleshooting Analyzer (from the Toolbox on the Exchange Management Console) :

- Select a task

- Click on trace control

- Click on set manual trace log

- On components to trace, choose Store.

- On trace tags, choose: tagQueryCi , tagQueryCiDump, and tagSearch

- Click on start tracing

- Then check the application log, once you see the event on the application log,

stop tracing.

- an MS Support Engineer will then analyze the *.etl resulting file


MS Support will then use an internal debugging tool to decrypt or transform the resulting etl file to a readable format, and analyze it and eventually give you the analyzis results.
