Office 2003 users can view/edit Office 2007 files

All versions of Office can play nice Crabby shows you how

There are a couple of ways to make sure that everyone is able to read, view, and work with Office 2007 documents, presentations, and workbooks.

• If you are the one who created the Office 2007 file, you can save a copy of it that is compatible with Word 97-2003, PowerPoint 97-2003, or Excel 97-2003. Click one or more of the links in the See also section to learn how to do that for each program.
• If you are the one who is opening a Word 2007, PowerPoint 2007, or Excel 2007 file with an earlier version, you can download the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats, which will allow you to do just that.
