How to Fix OneDrive Sync Issues Caused by Different Accounts

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Attempting to sync or back up local folders to OneDrive cloud storage.
Observed behavior: The backup or sync process fails because the account signed into the desktop application differs from the online account.

Before you start

Ensure you have the exact login credentials (email and password) for the correct OneDrive account you intend to use before unlinking your current setup.

Solution 1Recommended

Unlink the Current Account and Clear OneDrive Credentials

Disconnect the mismatched account from your computer and clear cached credentials to allow the correct account to authenticate and sync.

When your local computer is signed into a different account (such as a personal account) than the online OneDrive service (like a work or school account), synchronization is blocked to prevent data conflicts. Re-authenticating the correct account by completely signing out and clearing the cache is the most effective fix.

Unlink your PC from OneDrive

Click the OneDrive cloud icon in your Windows taskbar system tray. Click the gear icon to open 'Settings', navigate to the 'Account' tab, and click the 'Unlink this PC' link.

Clear cached Windows credentials

Open the Windows Start menu, search for 'Credential Manager', and open the application. Click on 'Windows Credentials', scroll down to locate any entries starting with 'OneDrive Cached Credential', and click 'Remove'.

Reset the OneDrive application cache

Press the Windows key + R to open the Run dialog box. Type '%localappdata%\Microsoft\OneDrive\onedrive.exe /reset' and press Enter. The OneDrive icon will disappear and reappear after a minute.

Sign in with the correct account

Open OneDrive from the Start menu if it doesn't launch automatically. Enter the email and password for the correct account you use online and follow the on-screen setup prompts to configure your sync folders.

Unlink the Current Account and Clear OneDrive Credentials

Sync Restored: Once signed in with the matching account, OneDrive will scan your folders and resume backing up your files without the account conflict error.

Frequently Asked Questions

Why does OneDrive say the account signed in is different?

This error typically occurs when you log into a Microsoft app or Windows using a work or school account, while your desktop OneDrive client is still tied to a personal account (or vice versa), creating an authentication conflict.

Will unlinking my PC from OneDrive delete my local files?

No, unlinking your PC only disconnects the account connection. Your files remain safe in the cloud, and any files or folders you previously downloaded will stay exactly where they are on your local hard drive.

How can I check which account is currently signed into my OneDrive?

Click the OneDrive cloud icon in your system tray, select the gear icon to open 'Settings', and look under the 'Account' tab. The currently signed-in email address will be displayed at the top of that section.
