- Product
- Microsoft Word for Mac
- Device & OS
- macOS
- Scenario
- Uploading or syncing changes to a shared, synchronized, or collaboratively edited document.
- Observed behavior
- Microsoft Word displays a conflict message preventing the document from saving or uploading changes properly to the server or cloud.
Before attempting to fix sync conflicts, immediately use the 'Save As' function from the File menu to save a local copy of your document to your Mac, preventing any accidental data loss.
Identify and Resolve Collaborative Sync Conflicts
Use this solution when editing a shared document on OneDrive or SharePoint to manually review and merge overlapping edits.
Upload conflicts primarily happen when multiple users edit the exact same section of a shared document simultaneously, or when a temporary network disconnection causes cloud synchronization to delay.
Look for a yellow notification banner at the top of your Word document indicating an upload failure. Click the 'Resolve' or 'Keep My Version' button to launch the conflict resolution pane.
Use the conflict resolution pane on the right side of the screen to manually compare your unsynced edits with the server's version. Choose which changes to keep and click 'Apply'.
Ensure your Mac is connected to a stable internet network. Check if the file is shared via OneDrive or SharePoint, and coordinate with other collaborators to avoid editing the same paragraphs simultaneously.

Review and Manage Track Changes
Unresolved tracked edits from multiple authors can sometimes trigger underlying file conflicts during cloud uploads.

Frequently Asked Questions
Why does Word for Mac show a 'changes conflict with other updates' error?
This error typically occurs when multiple people are editing a shared cloud document simultaneously and modify the same content, or when there is a delay in syncing your local Mac changes with OneDrive or SharePoint.
How do I securely save my changes if Word refuses to upload them?
You should immediately navigate to 'File' > 'Save As' and save a separate copy of the document locally onto your Mac's hard drive. This ensures your unsynced work is secure while you troubleshoot the primary file's cloud connection.
Can having the 'Track Changes' feature enabled cause sync issues in shared documents?
Yes, heavily tracked documents or unresolved changes from multiple authors can occasionally complicate the co-authoring process and trigger conflict errors. Managing and accepting these tracked changes often resolves the underlying error.
