Interesting post from an old-timer regarding Microsoft's adherence to standards. I can't find the reference, but I'm betting that it goes way back (i.e. Microsoft Mail is what they now call Exchange):

As the Microsoft Mail folks explained to Eric Allman when he pointed out

The ODF Alliance has prepared a Fact Sheet for governments and others interested in how Microsoft's SP2 for Office 2007 handles ODF. The report revealed 'serious shortcomings that, left unaddressed, would break the open standards based interoperability that the marketplace, especially governments, is demanding.

The Open Document Format (ODF) Alliance has analyzed whether Microsoft’s Service Pack 2 for Office 2007 fulfills the promise for compatibility with the free document standard. Their findings give little reason to hope.

• La ODF Alliance avisa a los gobiernos sobre el soporte ODF de Office 2007 SP2



• ODF Alliance alerta governos sobre o 'suporte' ODF do Office 2007 SP2



• Compatibilidad de Office 2007 con ODF despierta sospechas
