Maximizer has the ability to log a history of changes made to entries in your Address Book. When Auditing is enabled; a history of the changes made to the basic fields; user-defined fields; notes; and documents of your entries is automatically saved to the audit log. You have to enable and configure Auditing preferences for the Address Book module to allow users to view audit logs. The size of your Address Book database may increase substantially when Auditing is turned on. The current size of the audit log file is displayed in the Auditing preferences page.
