Question details
Users are seeing numerous unexpected style changes in the Reviewing Pane when merging documents from multiple authors.

- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Combining Word documents with Track Changes enabled from multiple users.
- Observed behavior
- The Reviewing Pane displays many style definition changes even if only a few headings or text segments were visibly edited.
Ensure you have access to the Developer tab in Microsoft Word, as it is required to access the necessary template settings. If it is not visible on your ribbon, you will need to enable it in your Word Options before proceeding.
Disable Automatic Style Updates in Templates
Disabling the automatic style update setting prevents Word from logging all template styles as new revisions when merging documents.
When documents from multiple users are combined, differing style definitions in their respective Normal.dotm templates can trigger massive formatting revisions. Disabling this automatic update ensures only actual user edits are tracked.
Open your Word document and navigate to the 'Developer' tab located on the top ribbon.
Click on the 'Document Template' button to open the Templates and Add-ins dialog box.
Under the Templates tab, locate and uncheck the box labeled 'Automatically update document styles'.
Click 'OK' to save your changes. Ensure you repeat this process for all affected documents before attempting to combine revisions again.

Frequently Asked Questions
Why does Track Changes show formatting changes I didn't make?
This usually happens when the 'Automatically update document styles' setting is enabled, causing Word to refresh and log all underlying template styles as new revisions when opening or merging documents.
How do I temporarily hide style changes in the Reviewing Pane?
You can hide them by going to the Review tab, clicking the 'Show Markup' dropdown, and unchecking 'Formatting'. This hides style revisions while keeping text insertions and deletions visible.
What if the automatic style update option is already unchecked?
If the option is disabled for all users and you still see unexpected styles, the issue might stem from conflicting default styles in the Normal.dotm templates across different computers, or from direct formatting applied over defined styles.
Does this style issue affect the printed document?
No, Track Changes logged in the Reviewing Pane do not alter the final print layout unless you specifically choose to print the document with the markup enabled.
