Set maximum message tracking logs age in Exchange Server 2007

Some times you need to increase the period for which the message tracking logs kept in your Exchange server. The default maximum age for message tracking logs in Microsoft Exchange server 2007 is 30 days:

Get-TransportServer <TransportServerName>| fl *track*

To set the maximum message tracking logs age to another period you can use the following command:

Set-TransportServer <TransportServerName> -MessageTrackingLogMaxAge dd.hh:mm:ss

Now check
Get-TransportServer <TransportServerName>| fl *track*
