If you are the first on your block to use MS OFFICE 2007, keep in mind that any files created in the application can not be opened in an earlier Office Suite. For example, saving a new Word document creates a “DOCX” extension. In order to make this file readable as a Word 2003 file, the document must be saved again in 2003 format to ensure compatibility. (Better yet it should be saved as a PDF before distributing!).

On the other hand, if you’ve received a 2007 file that you can’t open with your 2003 office version, consider downloading a compatibility pack from the Microsoft Site which will convert the file into a readable format.
