It sounds like the
Track Changes feature may be locked or protected in some way. Here are a few steps you can try to resolve the issue:
- Check if the document is protected: Go to the Review tab and click on the Protect Document button. If the Protect Document button is highlighted, it means the document is protected. Click on it to unprotect the document.
- Check if the Track Changes feature is locked: Go to the Review tab and click on the Track Changes button. If the Track Changes button is highlighted, it means the feature is locked. Click on it to unlock the feature.
- Check if the document is in Compatibility Mode: If the document was created in an earlier version of Word, it may be in Compatibility Mode. Go to the File tab and click on Info. If it says "Compatibility Mode" next to the document name, click on Convert to update the document to the latest version of Word.
- Try copying the content to a new document: If none of the above steps work, try copying the content to a new document. Go to the Home tab, select all the content in the document (Ctrl+A), and copy it (Ctrl+C). Open a new document and paste the content (Ctrl+V). Turn on Track Changes and see if the Accept-Reject buttons work.
I hope one of these steps helps you resolve the issue.
