I have been unable to access my OneDrive Personal Vault for approximately two weeks. Until last month, it worked normally. I have not deleted any files or folders. When I attempt to open Personal Vault, I receive the following error every time: "Try refreshing the page Please try again or refresh the page. unlockRequired Correlation ID: 90cf2ba2-70db-2001-50d0-d22cd0cafb0d" Troubleshooting already attempted: - Multiple browsers (Edge, Chrome, Firefox, Safari) - Freshly installed browser with no extensions - Incognito/private browsing mode - OneDrive Android app (including full reinstall) - Signing out and back in - Clearing cache and cookies My Microsoft 365 subscription is active and current. The files and folders in my Vault are critical and I need access restored urgently. Please escalate this to the OneDrive engineering team. I need confirmation that my Vault contents are intact and assistance unlocking it.

    The vault contents are not indicated as deleted by the available guidance, but direct confirmation of file integrity is not provided here.

    For an unlockRequired Personal Vault failure that persists across browsers, private mode, Android reinstall, sign-out/sign-in, and multiple devices, the supported actions are:

    1. In OneDrive, select Personal Vault and complete identity verification again using an available method such as Text, email, or the Microsoft Authenticator app.
    2. If the vault opens at all, close any files stored in Personal Vault and wait for sync to complete before locking it again.
    3. If sync is slow because of large files, increase the Personal Vault auto-lock time from OneDrive > Settings > Account > Change your Personal Vault auto-lock time.
    4. Verify the Microsoft account can sign in normally through the Microsoft Account dashboard.
    5. Make sure the latest version of OneDrive is installed.
    6. If sign-in still fails, check whether a firewall, VPN configuration, or internet provider is interfering with OneDrive access.
    7. If the account shows as unavailable or blocked, use the Microsoft services account reset page. A temporary block after security verification or sharing many files can be removed within 24 hours.
    8. For technical support, use Contact Microsoft Support, enter the problem, and select Get Help. If needed, select Contact Support to be routed to the best support option.

    A relevant community-reported workaround for persistent unlockRequired behavior was to temporarily remove and reconfigure Microsoft account verification methods so sign-in used only the account password, then re-enable Microsoft Authenticator and other verification methods afterward. That report is not official product guidance, but it matches this symptom pattern.
