Microsoft Office 2007 Compatibility Page

Microsoft's Office 2007 introduced a new file format for each application within the Office suite.  Using the new formats can pose a problem for users who do not have Office 2007, as the new files are not backwards-compatible.  This means older versions of MS Office cannot natively open the new file formats.

To ensure all users will be able to open your documents, we recommend saving as a 97-2003 compatible format.   Please read Saving Documents in Word 2007 for more information on saving backwards-compatible files in Word.   The same steps can be applied to the other applications in the Office suite.

The new file formats are:
  • Word: .docx
  • Powerpoint: .pptx
  • Excel: .xlsx
