For troubleshooting purposes, it may become necessary to increase or decrease the number of tracking log files for mail in Microsoft Exchange Server. This article describes how to adjust this number.


WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

The following registry key can be modified to change the number of days covered by the tracking log:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeSA\Parameters\OldLogsCleaningInterval(Days): Reg_DWORD: 0x7

By changing the OldLogsCleaningInterval(Days) value, you can increase or decrease the number of tracking log files for that Exchange Server computer.
