Countering Google’s recent suggestion to companies, about using their current Office version with Google Docs rather than upgrading to Office 2010, Microsoft has overtly dismissed Google’s claims pertaining to Office-Docs interoperability.

Google’s suggestion was largely based on the rationale that Google Docs enhances Office 2003 and 2007 in the sense that it boasts the capability of storing Microsoft Office documents in the cloud and sharing them in their original format.

In addition, Google has also revealed that it soon intends adding real-time collaboration from within Office documents, using the technology gained from its DocVerse takeover in March.

However, disputing Google’s suggestion, Alex Payne, director of online product management team at Microsoft, said that it is erroneous to suppose that Office 2007 and 2003 can work together seamlessly – partly due to the fact that Google Docs’ conversion of Office files into a different file format for viewing and editing, actually wipes out certain page elements like fonts, styles, and charts.

Noting that Microsoft has ensured that the rich client-created Office 2010 files are “almost identical” when viewed via a Web browser using Office Web Apps, Payne said in a blog poston Tuesday: “We strive for high fidelity between the PC, phone and the browser and we are very excited about the new collaboration capabilities this will enable.”
