Is it possible to include or ignore specific .PST content during scanning of a .PST file via Endpoint?


A new advanced setting, Discover.IncludePstMessageClasses, is available in version 9.0.1. This setting is a comma-separated list of PST message classes. While scanning PST files, only emails belonging to message classes that are defined in this setting will be scanned. This setting overrides the Discover.IgnorePstMessageClasses setting. For example, when both the settings are defined, Discover.IncludePstMessageClasses takes precedence. Access the Discover.IncludePstMessageClasses setting from the Advanced tab on the Monitor Detail page for each detection server. This setting is only relevant for Discover servers.
