Office File Validation General Availability Announcement

It is my pleasure to announce the general availability of Microsoft Office File Validation for Office 2003 and Office 2007.

Office File Validation is an Add-in that will validate incoming Office files to make sure the file structure conforms to the Office definition.

Today we released the Microsoft Office File Validation Security Advisory along with supporting documentation for Office File Validation. Below is the structure of the release and supporting articles.


If you need information on how this all fits together you can check out the TechNet article or review the Knowledge Base articles mentioned above.

Office File Validation will be available for Office 2003 and Office 2007 via Microsoft Update in the near future. At this time we didn’t release this update to the Windows Server Update Services (WSUS) service.

    After this update installed I attempted to open a very large Excel spreadsheet (22,358KB)and Excel locked up and I had to force close it through task manager.  I attempted to re-open the same spreadsheed after a successful re-start of Windows and Excel still locked up.  I then uninstalled the update.  After unistallation was completed I was able to successfully open the spreadsheet.  Making the Add-In a "high priority" update, so that it Auto updates on a system (if that option is selected) is a fail.  It appears to be a bit buggy if it locks up Excel (as in my instance)  This should be an optional update.
