When making decisions on what SCL levels to set in the Intelligent Message Filter (IMF) configuration, it’s useful to see what SCL is stamped on particular mail.
The following is an Outlook configuration file provided by Paul Bowden that will allow you to configure Outlook to expose the SCL property. Copy the SCL.CFG text and save it as SCL.CFG (in the same location as the .ICO files, usually program files\...\office 11\forms\language ID), then follow the instructions below to install it.
