New features in Microsoft Word 2007, 2010 and 2013 (and likely in future version) may not work or display properly in a document that is opened in an earlier version of Word (Word 2003 or earlier). Some features that are not supported in earlier versions of Word are disabled in Compatibilty Mode. If you wish to remove the compatibility mode feature from a specific document you will have to have Word 2007 or newer then perform these actions:

  1. Open the document.
  2. From the File tab, choose Info.
  3. Click the Convert button.
  4. You will be prompted with a dialog box to confirm this action. Click OK.
  5. The document will be replaced by the converted version and you will no longer see [Compatibility Mode] in the title bar.
