A. Microsoft provides a utility, which you can download at http://www.microsoft.com/downloads/details.aspx?FamilyId=E7F73F10-7933-40F3-B07E-EBF38DF3400D&displaylang=en . The tool lets you easily enable and disable envelope journaling. After you download the tool, use the following command to enable envelope journaling:
C:\temp\Exejcfg>exejcfg -eTo disable envelop journaling, run the same command but with the -d option instead of -e. You MUST NOT have the JournalBCC registry value enabled or envelope journaling won't function. Envelope journaling has BCC functionality built in so the registry value isn't needed anyway.
