Make your content more accessible to everyone with the built-in Microsoft Accessibility Checker in Word, PowerPoint, Outlook and Excel.  Enable the "Keep accessibility checker running while I work", to add the Accessibility notification to the status bar. An “Accessibility: Investigate” message indicates there are issues that need your attention.  Review and resolve errors, warnings and Intelligent Services listed in the inspection results listed in the Accessibility pane. Once all have been dealt with the notification will change to Accessibility: Good to go!
