DisplayName *		The DisplayName parameter specifies the display name for the message classification instance. The display name is used by Outlook users to select the appropriate message classification before they send a message. The message classification XML file must be present on the sender's computer for the display name to be displayed. If the UserDisplayEnabled parameter is set to $true, the display name is displayed for the recipient, even if no message classification XML file is installed.
