As a user, I would like to share my MSOffice files as PDF only, removing, during conversion, any sensitive metadata as well as any risky objects, including hyperlinks, macros and activex objects that are ole'd or otherwise embedded.
Runexy have stated that it is a high priority for Hitachi. Robin called it 'detoxification' but I think that is just translation. In the document management world I see it referred to as metadata cleaning.
AFAIK GroupDocs does not advertise this capability.
