Question details

The user is experiencing synchronization conflicts in OneDrive when working with linked Excel files, causing prompts about other users making changes and risking data loss if changes are discarded.

How to Fix OneDrive Excel Synchronization Conflicts

Product: Microsoft Excel and OneDrive
Device & OS: not provided
Scenario: Collaborating on or syncing linked Excel files via OneDrive.
Observed behavior: OneDrive displays a conflict error indicating another user made changes. Discarding changes reverts the document to an older version, resulting in lost work.

Before you start

Before proceeding, save a local copy of your current Excel file with a different name to prevent any accidental data loss while resolving the sync conflict.

Solution 1Recommended

Check Sync Status and Restart OneDrive

Often, temporary network glitches or paused states cause synchronization conflicts. Restarting OneDrive can refresh the connection and resolve the error.

A simple restart of the OneDrive application forces it to reconnect to the Microsoft servers and re-evaluate file statuses, which frequently clears up artificial sync conflicts.

Open OneDrive

Click the OneDrive cloud icon located in your system tray (Windows) or menu bar (Mac).

Pause and Resume Syncing

Click the gear icon (Help & Settings) and select 'Pause syncing', then choose a short duration. Wait a moment, click the gear icon again, and select 'Resume syncing'.

Restart the App

If the issue persists, select 'Quit OneDrive' from the settings menu. Open your Start menu or Applications folder and relaunch the OneDrive app to initiate a fresh sync.

Safe Troubleshooting: Restarting the app is a safe first step that does not delete any files or alter your account settings.

Solution 2

Unlink and Relink Your PC to OneDrive

If restarting does not work, unlinking and reconnecting your account forces OneDrive to perform a complete synchronization check of your linked Excel files.

Solution 3

Restore Lost Data via Version History

If you have already discarded changes and accidentally restored an older version of your Excel file, you can recover your previous work using Version History.

Frequently Asked Questions

Why does OneDrive say another user made changes when I am the only one editing?

This can happen if you have the file open on multiple devices simultaneously, or if a background sync was delayed due to internet issues, causing OneDrive to treat your own previous session as a different user.

How can I prevent Excel sync conflicts in the future?

Ensure you are using the latest version of the OneDrive client, maintain a stable internet connection, and utilize the AutoSave feature. Closing Excel files when they are not actively in use also drastically reduces the chance of sync conflicts.

Will I lose my data if I click 'Discard Changes' during a sync error?

Yes, clicking 'Discard Changes' will overwrite your local version with the version stored on the OneDrive server, potentially causing you to lose your recent edits. Always use 'Save a Copy' to preserve your current work before resolving the conflict.
