Hi, I’m Peter Frem, a Senior Program Manager leading an effort across Office 365 to make it easier for you to create documents and communications that are accessible to everyone.

When you create a document, ensuring its accessibility is your responsibility. By creating accessible documents, you guarantee that they can be accessed, read, and used by more people. Simple things like using headings to easily navigate a long document, or using text contrast that’s easy to read in a variety of lighting conditions make a big difference. We’re excited to share a small update with big impact designed to help you ensure you have the right files to make your documents accessible.

Modern documents are all about empowerment and inclusion

The modern Office file format (Open XML Format) provides many advantages for users of Office 365, including industry-leading collaboration or engaging 3D content. The benefits also extend to accessibility scenarios, providing people with disabilities and everyone they work with robust capabilities to make their documents accessible.

In this update to the Accessibility Checker, we are introducing a simple flow to check and ensure you’re using the most accessible file type. If you are not, we’ll offer a quick way to help you ensure that your document is optimized and easily consumable by people with disabilities. For example:

  • In the Accessibility Checker pane, you’re encouraged to convert your document into a format that can take full advantage of Office 365’s accessibility capabilities.

  • In the status bar notification tray, you’re given a reminder that the Accessibility Checker is unavailable for the current document type.

  • In File > Info when reviewing file information, you are prompted to convert the document as it is currently in a reduced-functionality mode.

As we continue to look for simple ways to get more documents to be accessible to more people, I hope you find this update useful and valuable. Please continue to share feedback so we can all work together to make documents accessible for everyone!

We typically release features over some time to ensure that things are working smoothly. This is true for Insiders as well. We highlight features that you may not have because they’re slowly releasing to larger numbers of Insiders. Sometimes we remove elements to further improve them based on your feedback. Though this is rare, we also reserve the option to pull a feature entirely out of the product, even if you, as Insiders, have had the opportunity to try them.


If you have any feedback or suggestions, you can submit them using the Help Improve Office (🙂) button in the top right corner of Word, PowerPoint, or Excel, or use the Help > Feedback menu.
