Fix OneDrive Account Already Connected Error on Mac
Question details
The user needs to resolve an account connection error preventing proper file synchronization, caused by having multiple versions of the OneDrive application installed simultaneously on a Mac.

- Product
- Microsoft OneDrive
- Device & OS
- macOS
- Scenario
- Setting up or running the OneDrive desktop application for file synchronization on a Mac device.
- Observed behavior
- The system triggers the error message 'Account Already Connected: another version of OneDrive is already connected,' leading to account conflicts and halted synchronization.
Verify that your important local files are safely backed up or correctly synced to the cloud before making any changes to your installed OneDrive applications.
Identify and Uninstall the Duplicate OneDrive Application
Determine which OneDrive client is correctly linked to your account, and remove the duplicate application to resolve the connection conflict.
This error typically occurs when users inadvertently install both the standalone version of OneDrive from the Microsoft website and the Mac App Store version. Removing the redundant application eliminates the background conflict.
Click the OneDrive cloud icon in your Mac's top menu bar, select 'Help & Settings' (gear icon), click 'Preferences', and go to the 'About' tab to view the version currently running.
Switch to the 'Account' tab in the Preferences menu to confirm which Microsoft account email address is actively syncing your local files through this specific client.
Open Finder and navigate to your 'Applications' folder. Locate the extra OneDrive application that is not connected to your primary account and drag it to the Trash.
Empty the Trash on your Mac, then open your Applications folder or Launchpad to launch the correct OneDrive application and ensure file syncing resumes normally.

Frequently Asked Questions
Why do I have two versions of OneDrive installed on my Mac?
This commonly happens if you downloaded the application from the Mac App Store and later downloaded another version directly from a web browser, resulting in two separate applications attempting to sync your files simultaneously.
Will deleting a duplicate OneDrive app erase my locally saved files?
No, simply dragging the extra OneDrive application file from your Applications folder to the Trash does not delete your local OneDrive folder or the files synchronized within it.
How do I add a second account without installing a second app?
You do not need multiple apps for multiple accounts. Open your single, active OneDrive application, go to 'Preferences', click the 'Account' tab, and select 'Add an account' to sign in with an additional Microsoft account.
How can I tell if my files are synced before I remove the duplicate?
Click the OneDrive icon in your Mac's menu bar. If the status reads 'Your files are synced' and there are no processing arrows over the icon, your local files have safely reached the cloud.
