SUMMARY

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.

MORE INFORMATION

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. The item can be a message, attachment, or folder, depending on the configuration selected as described in the following section.

For example, if Log Downloads is set to 1 in the ParametersPublic registry key, every time a user moves or copies a message with an attachment to the user's Personal Folder file, an event is logged.

The following information is logged:

  • User name
  • Mailbox name
  • Size of item downloaded
  • Document type
  • Document identifier
The following example is an event generated by the download feature.
   Event ID: 7102

   Category: Download
   Description:

You establish download logging by editing the registry of a Microsoft Exchange Server with RegEdit, a Windows NT administrative tool. The values you add apply to all public and private folders on the server.
