How to Fix Microsoft 365 Family Files Syncing to the Wrong Computer

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Two users in a Microsoft 365 Family plan are unexpectedly seeing each other's files on their respective computer desktops.
Observed behavior: Files from one user's computer are syncing and appearing on the other user's desktop through OneDrive.

Before you start

Before making any changes to your OneDrive settings, log in to OneDrive on the web to verify which account owns the files and create local backups of any important data to prevent accidental loss.

Solution 1Recommended

Verify and Unlink the Conflicting OneDrive Account

Check which Microsoft account is currently signed into OneDrive on the affected computer and unlink it if it is the wrong account.

Often, files cross-sync because one computer was accidentally signed into another family member's Microsoft account. Unlinking the incorrect account will stop the syncing process immediately without deleting the files from the cloud server.

Open OneDrive settings

Click the OneDrive cloud icon located in the Windows taskbar system tray, then select the gear icon and click on 'Settings'.

Check the signed-in account

Navigate to the 'Account' tab to verify the email address currently signed in. Check if it belongs to you or the other family member.

Unlink the PC

If the account is incorrect, click 'Unlink this PC' and confirm your choice. This severs the connection between the computer and that specific OneDrive account.

Sign in with the correct account

Restart OneDrive and sign back in using your own distinct Microsoft 365 Family account credentials.

Verify and Unlink the Conflicting OneDrive Account

Data Safety: Unlinking an account will not delete files from the cloud. They remain completely accessible via OneDrive on the web using that account's login.

Solution 2

Disable Desktop Folder Backup in OneDrive

Stop OneDrive from merging desktop files by disabling the automatic Desktop folder backup feature.

Frequently Asked Questions

Will unlinking my OneDrive account delete my personal files?

No, unlinking your PC only stops the active syncing process. Your files will remain safely stored in the OneDrive cloud and can still be accessed at any time through your web browser.

Why are my desktop files appearing on my family member's computer?

This typically happens if both computers are accidentally signed into the identical Microsoft account, and OneDrive's 'Desktop Backup' feature is enabled on both devices, causing the folders to merge.

Can I recover files if I accidentally delete them from the synced desktop?

Yes, deleted OneDrive files are usually moved to the computer's local Recycle Bin as well as the OneDrive online Recycle Bin. You can log into OneDrive on the web to restore them within 30 days.
