Is Office 2007 backward compatible with Office 2003?
Office 2007 is not backward compatible with earlier versions of Microsoft Office in a traditional way, but it is fairly easy to make Office 2003 able to read Office 2007 files. Microsoft has a compatibility plug-in available to solve this problem, called: Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats. You may install it from the Microsoft Download site or from the BioHelp server locally. After installing it, Office 2003 will be able to open and edit Office 2007 files. Another, even simpler option, is to use the Save As option to save files in Office 2003 file format from Office 2007.
