Emails are convenient for many, but a wide range of disabilities can make the format difficult to use for many of our friends, family, and colleagues. Make sure that your emails are fully accessible by using Microsoft Outlook’s built-in Accessibility Checker.

How to Access the Accessibility Checker in Outlook

With Outlook’s Accessibility Checker, you can scan your emails for various issues that might pose issues for people with disabilities. The tool will look for things like images missing the alternative text that people who use screen reader rely on to understand images image. It will make sure that tables have simple structures that can be navigated by assistive technology, check your heading styles to simplify navigation, and generally ensure that your email follows best practices for accessibility.

To check any Microsoft Outlook email for accessibility issues, click the “Review” tab on the ribbon while composing an email, and select “Check Accessibility.” This button is at the end of the bar, so if your email window isn’t full screen you might need to click on the three horizontal dots on the right to access this button. If you’re using Outlook on a Mac, the “Check Accessibility” button can be found under the “Options” tab.
