This policy setting controls how Office handles documents when they fail file validation. If you enable this policy setting, you can configure the following options for files that fail file validation:- Block files completely. Users cannot open the files.- Open files in Protected View and disallow edit. Users cannot edit the files. This is also how Office handles the files if you disable this policy setting.- Open files in Protected View and allow edit. Users can edit the files. This is also how Office handles the files if you do not configure this policy setting.If you disable this policy setting, Office follows the "Open files in Protected View and disallow edit" behavior. If you do not configure this policy setting, Office follows the "Open files in Protected View and allow edit" behavior.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
