You must always configure the FlexEngine logoff command to run from a logoff script. You can add the FlexEngine logoff command to an existing logoff script or call it directly as if it were a logoff script. Use User Configuration\Windows Settings\Scripts for this purpose.
Configure the following logoff command that will run during the logoff process:
C:\Program Files\Immidio\Flex Profiles\FlexEngine.exe -s
This command reads the settings configured through the User Environment Manager Group Policy Object and performs the path-based export accordingly.
