Unlink and Relink Your OneDrive Account

Signing out and back into OneDrive forces the application to refresh its connection to the cloud and restart the syncing process from scratch.

Often, temporary authentication glitches or network interruptions cause the sync process to stall. Relinking your account is a safe and effective way to reset the connection without losing data.

1
Access OneDrive Settings

Click on the OneDrive cloud icon located in the Mac menu bar at the top of your screen.

2
Open Account Settings

Select 'Help & Settings' (the gear icon) from the dropdown menu, then click on 'Settings'.

3
Sign Out

Navigate to the 'Account' tab and click on the 'Sign out' button.

4
Sign In Again

Relaunch the OneDrive application, sign in with your Microsoft credentials, and allow the initial file synchronization to complete.

Unlink and Relink Your OneDrive Account
Data Safety: Unlinking your account will not delete your cloud files. It simply disconnects your Mac temporarily until you sign back in.

Frequently Asked Questions

Why does my OneDrive only show an empty attachment folder?

This usually happens when the initial sync is interrupted, blocked by antivirus software, or due to account authentication glitches between your Mac and the Microsoft servers.

Will reinstalling OneDrive delete my cloud files?

No, uninstalling the OneDrive application from your Mac will only remove the local software. Your files remain completely secure in your online OneDrive account.

How do I know if my antivirus is blocking OneDrive?

You can temporarily disable your antivirus software or Mac firewall to see if the missing files begin to sync. If they do, you will need to add OneDrive to your antivirus software's exception list.
