How to Fix Word Heading Styles Changing in Microsoft Teams
Question details
Users experience unpredictable changes to Word heading styles, such as fonts automatically switching or indentation shifting, when multiple contributors edit a document hosted on Microsoft Teams.
- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Co-authoring and editing a shared Word document with multiple contributors in Microsoft Teams.
- Observed behavior
- Document heading styles automatically and inconsistently change formats, overriding the original layout settings of the document creator.
Ensure all contributors have temporarily closed the shared document in Microsoft Teams, and save a backup copy of the original file to your local computer before adjusting template settings.
Disable Automatically Update Document Styles
Turning off this setting prevents Word from applying local template styles from other contributors' computers to the shared document.
When 'Automatically update document styles' is active, Word attempts to match the document's formatting to the Normal.dotm template stored on the computer of the person currently editing. This causes random formatting changes during co-authoring.
Open Microsoft Word, go to File > Options, and select Customize Ribbon from the left menu. Check the box for Developer in the right pane and click OK.
Navigate to the newly added Developer tab on the Word ribbon and click on Document Template in the Templates group.
In the Templates and Add-ins dialog box, uncheck the option for 'Automatically update document styles'. Click OK, save the document, and upload this updated version back to Teams.
Isolate and Re-upload a Clean Copy
If sync issues in Teams are causing stubborn conflicts, working locally and uploading a fresh copy can clear the glitch.

Frequently Asked Questions
Why do Word styles change based on who opens the document?
If the 'Automatically update document styles' setting is enabled, Word pulls formatting rules from the default Normal.dotm template stored on the specific computer of the person opening the file, which overrides the document's embedded styles.
How do I access the Templates and Add-ins dialog without the Developer tab?
You cannot access this specific dialog without the Developer tab. You must first enable it by navigating to File > Options > Customize Ribbon and checking the 'Developer' option in the right-hand column.
Can I lock formatting to prevent contributors from changing styles?
Yes. You can restrict formatting by going to the Review tab, clicking Restrict Editing, and checking 'Limit formatting to a selection of styles'. This prevents co-authors from introducing new, conflicting styles into the document.
