Why Word and PowerPoint Accessibility Checker Results Differ Between Office Versions
Question details
Users notice differing Accessibility Checker results when sharing Word or PowerPoint files between different Office software versions.
- Product
- Microsoft Word and PowerPoint
- Device & OS
- not provided
- Scenario
- Checking document accessibility for Section 508 compliance across different Microsoft Office builds or versions.
- Observed behavior
- The Accessibility Checker identifies different issues or additional errors depending on whether the user opens the file in Microsoft 365 or Office 2016.
Check the exact version and build number of Microsoft Office on both your computer and the recipient's computer to understand where the discrepancy originates.
Standardize Office Versions and Manually Validate Findings
Comparing documents on the exact same Office build and manually reviewing flagged issues will help resolve discrepancies and ensure true accessibility compliance.
Microsoft continuously updates its Accessibility Checker rules. Newer versions, such as Microsoft 365, often catch issues that older desktop versions like Office 2016 ignore.
Because automated checkers cannot understand context, achieving true Section 508 compliance requires manual validation of the reported errors to eliminate false positives.
Open Word or PowerPoint, click on 'File' in the top-left corner, and select 'Account'. Look under 'Product Information' to locate your exact Version and Build number (e.g., Version 2008, Build 13127.21348).
Contact the client or colleague and ask them to check their Office version using the same method. Whenever possible, open the document using the exact same Office version and build to compare the Accessibility Checker results accurately.
Open the Accessibility pane by clicking 'Review' > 'Check Accessibility'. Go through each reported error, warning, or tip. Manually verify if the issue actually impacts readability, as not every automated finding is a genuine barrier.

Frequently Asked Questions
Why does Microsoft 365 show more accessibility errors than Office 2016?
Microsoft 365 receives continuous background updates, which include newer and stricter accessibility validation rules. Older perpetual desktop versions like Office 2016 do not receive these updated rule sets, leading to different results when checking the exact same document.
Can I rely solely on the Accessibility Checker for Section 508 compliance?
No. While the automated Accessibility Checker is an excellent starting point, it cannot evaluate subjective elements such as logical reading order, color contrast context, or the meaningfulness of alternative text. Manual review is always required for full compliance.
How do I find the build number in Microsoft Word or PowerPoint?
Open your application, click on 'File' in the top ribbon, select 'Account' (or 'Help' in some older versions), and look under the 'Product Information' section. You will see the Version and Build numbers listed next to the 'About Word' or 'About PowerPoint' button.
Does WPS Office support Microsoft Office file formats?
Yes, WPS Office offers excellent, native compatibility with Microsoft Word, Excel, and PowerPoint file formats, ensuring that your documents look consistent and maintain their formatting across different platforms and devices.
