I have a client who wishes to remove hidden data (their main problem is with track changes) from Word documents automatically if they are emailed out of the company. Currently they are using MAILSweeper which appears to allow 3rd party executables to run. There is a command line version of Remove Hidden Data called OffRHD.exe, but is this safe to run in a configuration like this? If this is distinctly "unsafe" then is there a way off permanently disabling "Track Changes" through group policy or some other setting? Ian
