Unlink and Relink Your OneDrive Account

Refreshing the connection between your PC and your Microsoft account can resolve local authentication errors preventing the Vault from unlocking.

Unlinking your PC will not delete your files. It safely disconnects your account so you can re-establish a fresh synchronization connection.

1
Open OneDrive Settings

Click the OneDrive cloud icon in your system tray, select the gear icon, and click Settings.

2
Unlink this PC

Navigate to the Account tab and click the 'Unlink this PC' link. Follow the prompts to confirm your action.

3
Sign Back In

Launch the OneDrive application again and sign in using your personal Microsoft account to relink your computer.

Sync Restored: Once relinked, OneDrive will verify your existing files. Wait a few moments before trying to open the Personal Vault again.

Frequently Asked Questions

Why does my Personal Vault work on the web but not on the desktop?

This usually happens due to corrupted local application data, synchronization glitches, or an outdated version of the OneDrive desktop client. The web version bypasses these local software issues.

Will resetting OneDrive delete my Personal Vault files?

No, resetting the OneDrive app only resets your sync settings and clears local application cache. All of your files safely remain intact on the cloud.

How do I know if my OneDrive issue is account-specific?

You can test this by logging out of your current account and signing in with a different personal Microsoft account. If the Personal Vault functions normally on the second account, the issue is tied to your primary account's specific settings.
