Newer versions of Microsoft Office allow you to check the accessibility of your documents. This comes in the form of an Accessibility Checker built into the program. The tool can be hard to find, so you can follow these steps to find the tool:

Windows

To find the checker in Windows, follow these steps:

Open a document
In the menu bar, towards the right, is a search bar with a lightbulb. Click on this.
Type in "Accessibility"
You should get an option for the Accessibility Checker. This is the tool you're looking for.
(Optional)Right click on the icon and click "Add to Quick Access Toolbar"
This will put the icon up at the top of the screen, so you don't have to search for it again.

Mac/OSX

The tool is easier to find in Mac, as it was added to the menu. Just follow these steps:

Click on the "Review" tab
Find Accessibility Checker in the menu that opens.
