Use the built in Accessibility Checkers
When creating documents in Microsoft Office (2007 or higher) or Adobe Acrobat (X or higher), use the built in Accessibility checker to address a number of common accessibility issues.
In Microsoft Office, use the left most tab (File in office 2010, 2013) and under Info, choose “Check Accessibility” under “Check for Issues” next to ‘Inspect Document.’
In Adobe, use the Action Wizards under Tools and choose the Accessibility Checker. Full instructions for Acrobat X Pro and Acrobat XI Pro.
