BuilInDocumentProperties not working in Word 2007 with C# / VS2008   

Hello,

I'm automating Word 2007 from an Outlook 2007 Addin done with VAS2008.

But I can't write any document property:
((Microsoft.Office.Core.DocumentProperties)(oWord.ActiveDocument.BuiltInDocumentProperties))[Word.WdBuiltInProperty.wdPropertyCategory].Value =categories;

I get a very strange error:

Unable to cast COM object of type 'System.__ComObject' to interface type 
'Microsoft.Office.Core.DocumentProperties'. This operation failed because the 
QueryInterface call on the COM component for the interface with IID 
'{2DF8D04D-5BFA-101B-BDE5-00AA0044DE52}' failed due to the following error: 
No such interface supported (Exception from HRESULT: 0x80004002 
(E_NOINTERFACE)).

Any idea?

Thanks.

Found the solution.
See http://support.microsoft.com/kb/303296/en-us

Why the MSDN library still hasn't been updated anywhere is beyond me.
