Identify Active Accounts and Sync Status

Determine which OneDrive instance corresponds to which account to prevent accidental data loss before making changes.

Seeing two OneDrive instances typically means two accounts (such as a personal and a work account) are configured in the sync client. Both clients can synchronize changes simultaneously.

1
Check the first OneDrive instance

Click the first OneDrive cloud icon in the Mac menu bar, click the gear icon (Help & Settings), and select Preferences.

2
Verify account details

Navigate to the Account tab to see the email address linked to this specific instance and check its current sync status.

3
Check the second instance

Repeat the process for the second OneDrive cloud icon in the menu bar to verify the identity and status of the other account.

Identify Active Accounts and Sync Status
Do Not Delete Folders Prematurely: Do not delete either OneDrive instance or its corresponding local folder until you are absolutely certain which account holds your essential files.
