Features are lost when you open a presentation created in an earlier version of PowerPoint

Because each version of Microsoft PowerPoint differs from preceding versions, you might find some features in presentations created in older versions do not work when you view them in PowerPoint 2010. When you use PowerPoint 2010 to view a presentation created in an older PowerPoint version, it opens in Compatibility mode. In compatibility mode, you can open, edit, and save PowerPoint 97–2003 presentations, but you won't be able to use all of the new PowerPoint 2010 features. Compatibility mode in PowerPoint 2010 is triggered when you do any of the following:

  • Open a file that was saved in PowerPoint 97–2003 (.ppt) format.
  • Convert a PowerPoint 2010 or 2007 (.pptx) file format to a PowerPoint 97–2003 file format by using Save As.
  • Set PowerPoint 2010 to save all presentations in PowerPoint 97–2003 format.

Because the following features are not supported in versions of PowerPoint later than PowerPoint 2003, if you save a file that contains data associated with these features in PowerPoint 2010, the data will be permanently lost:
