DTOO203 - Office System - Legacy format signatures must be enabled.

Information

Office applications use the XML-based XMLDSIG format to attach digital signatures to documents, including Office 97-2003 binary documents. XMLDSIG signatures are not recognized by Office 2003 applications or previous versions. If an Office user opens an Excel, PowerPoint, or Word binary document with an XMLDSIG signature attached, the signature will be lost.

Solution

Set he policy value for User Configuration -> Administrative Templates -> Microsoft Office 2010 -> Signing 'Legacy format signatures' to 'Enabled'.
