How to configure directory size settings for message tracking logs and for audit logs in Exchange Server 2007

This article describes how to configure directory size limits for message tracking logs and for managed folder audit logs in Microsoft Exchange Server 2007. These size limits apply to each database.

You can use the Exchange Management Shell to configure directory size limits for log files in Exchange Server 2007. The MessageTrackingLogMaxDirectorySize parameter is used to configure the maximum limit for directory space to be allocated for message tracking logs. The LogDirectorySizeLimitForManagedFolders parameter is used to configure the maximum limit for directory space to be allocated for managed folder audit logs.

When you configure directory size limits for audit logs or for message tracking logs, the limits apply to each database. The following example shows the total space that log files can occupy in a given scenario: Therefore, if you configure both parameters in this example, these two types of log files can occupy a total of 20 GB of directory space.

Note All directory size limit parameters for audit logs also apply in a similar manner to each database.

Units that you can use for size limits

Alternatively, you can configure the parameter by using the text string "Unlimited" (without the quotation marks).

The following table describes the various letters that you can use as qualifiers. Note Integers that do not include a qualifier are treated as bytes.
