Fix Track Changes Unavailable in Word Online WOPI Integration
Question details
The user is unable to access the Track Changes feature when embedding Word Online through a WOPI iframe, despite the feature being available in the desktop application and standalone Word Online.

- Product
- Word Online
- Device & OS
- not provided
- Scenario
- Integrating Word Online on a custom server or application using the WOPI protocol and attempting to use document review features.
- Observed behavior
- The Track Changes feature is not visible or available in the Word Online interface when accessed through a WOPI iframe deployment.
Ensure you have administrative access to your WOPI host configuration and verify that your integration is using the latest supported WOPI protocol capabilities.
Verify Feature Availability Outside WOPI
Test Word Online directly to determine whether the missing feature is a limitation of the specific WOPI deployment or a general account issue.
WOPI deployments do not automatically expose every feature available in the standard Word Online application. Feature availability depends heavily on your host configuration and the supported protocol capabilities.
Launch a web browser and navigate directly to the standalone Word Online portal without using your custom WOPI iframe integration.
Upload or open the document you wish to edit directly in the Word Online interface.
Navigate to the 'Review' tab on the top ribbon and look for the Track Changes feature. If it is visible here but not in your integration, the issue lies within the WOPI protocol limitations.

Submit Feedback to Microsoft
Report the lack of WOPI feature parity directly to Microsoft to help developers prioritize future protocol updates.
Use WPS Office for Seamless Track Changes and Collaboration

- 1. Install WPS Office: Download and install the free version of WPS Office on your desktop or mobile device.
- 2. Open your document: Launch WPS Writer and open your .docx document.
- 3. Enable Track Changes: Go to the Review tab in the ribbon and click 'Track Changes' to start editing with full markup support.

Frequently Asked Questions
Why is Track Changes missing in my WOPI integration?
WOPI deployments do not expose every feature available in the standalone Word Online application. Certain advanced review features, including Track Changes, may be disabled or unsupported depending on the host configuration and the specific version of the WOPI protocol being used.
Can I force enable Track Changes in a WOPI iframe?
Currently, there is no direct parameter to force-enable Track Changes if it is not supported by your WOPI host environment's protocol capabilities. You must rely on official updates from Microsoft regarding WOPI feature parity.
Does Track Changes work in the Word desktop application?
Yes, Track Changes is fully supported and enabled by default in the standard Microsoft Word desktop application, as well as the direct web version of Word Online when accessed outside of a WOPI iframe.
