The Microsoft Exchange Server download logging feature writes events to the Windows NT Event Log when users download attachments, messages, and folders from public or private folders. You can use this information for billing or tracking download costs.
A download event is logged when the user moves or copies an item from the private or public information store to a different store, such as a personal folder file (.pst). The item can be a message, attachment, or folder, depending on the configuration you have selected.
The following information is logged:
For example, if Log Downloads is set to 1 in the ParametersPublic registry subkey, an event is logged every time a user moves or copies a message with an attachment to the user's personal folder file.
