Exchange 2007 Messaging Tracking

This is an interesting one I found.  We set Message Tracking on out Hub Role servers so it would purge the logs after 30 days .. nice and simple. 

MessageTrackingLogEnabled               : True
MessageTrackingLogMaxAge                : 30.00:00:00
MessageTrackingLogMaxDirectorySize      : 250MB
MessageTrackingLogMaxFileSize           : 10MB
MessageTrackingLogPath                  : F:Program FilesMicrosoftExchange ServerTransportRolesLogsMessageTracking
MessageTrackingLogSubjectLoggingEnabled : True

So, I need to look for some logs over Easter and they where no there!?!  As you can see Message Tracking has another setting MessageTrackingLogMaxDirectorySize and my logs amounted to 240mb which is why I couldn’t find them.

So, make sure you have set MessageTrackingLogMaxDirectorySize to a decent size, like 2gb?  You can do this by running:

Set-TransportServer   -MessageTrackingLogMaxDirectorySize 2gb

Also  make sure these setting are the same on any Mailbox role, as they have Message Tracking logs too!

MessageTrackingLogEnabled               : True
MessageTrackingLogMaxAge                : 30.00:00:00
MessageTrackingLogMaxDirectorySize      : 250MB
MessageTrackingLogMaxFileSize           : 10MB
MessageTrackingLogPath                  : C:Program FilesMicrosoftExchange ServerTransportRolesLogsMessageTracking
MessageTrackingLogSubjectLoggingEnabled : True

But to set it on a Mailbox Role you need to run:

Set-MailboxServer   -MessageTrackingLogMaxDirectorySize 2gb
