A registry key setting is available that allows administrators to change how documents behave when a file fails validation.
The feature, previously only available for supported editions of Microsoft Office 2010, is designed to make it easier for customers to protect themselves from Office files that may contain malformed data, such as unsolicited Office files received from unknown or known sources, by scanning and validating files before they are opened.

If Office File Validation detects that a file’s structure does not follow all rules described in the schema, the file does not pass validation.
File format attacks occur most frequently in files that are stored in Office binary file formats.
For information on how to manually install the Office File Validation Add-in and prerequisite updates, see the Tech Net article, Office File Validation for Office 2003 and Office 2007.
As of June 28, 2011, the Office File Validation Add-in can also be installed by checking online for updates from Microsoft Update or by using the Microsoft Update service.
The Office File Validation feature helps prevent file format attacks by scanning and validating files before they are opened.
To validate files, Office File Validation compares a file’s structure to a predefined file schema, which is a set of rules that define what a readable file looks like.
These registry keys prevent files that are stored in the Office binary file format from being scanned and validated.
