Device & OS: not provided
Scenario: Accessing securely stored files on a mobile device after an app restart loop or cache reset.

Solution 1Recommended

Access Personal Vault Directly and Verify Account

Personal Vault files are hidden from standard search results for privacy. You must navigate to it directly and ensure you are using the correct account.

OneDrive intentionally excludes Personal Vault items from the standard search bar to protect your privacy. Searching for a file name will yield zero results if the file is locked in the Vault.

Open the Files tab

Launch the OneDrive mobile app and tap on the 'Files' tab located at the bottom navigation menu.

Verify your Microsoft account

Tap on your user profile icon (usually at the top left or right) to verify you are signed into the exact same Microsoft account used on the web version where the files are visible.

Locate Personal Vault manually

Scroll through your root file directory to locate the 'Personal Vault' icon directly, rather than using the search bar.

Complete identity verification

Tap on the Personal Vault folder and complete the required identity verification (such as a PIN, biometric fingerprint, or SMS code) to unlock and display your files.

Privacy feature: Once unlocked, the files will remain accessible for a few minutes before the Vault automatically locks itself again.

Solution 2

Update or Reinstall the OneDrive App

A cache reset or app restart loop can cause sync issues. Updating or reinstalling the app forces a fresh sync with the cloud servers.

Solution 3

Verify Files on OneDrive Web and Check Recycle Bin

If files are completely missing, check the web version's Recycle Bin to ensure they weren't accidentally deleted during a sync glitch.

Frequently Asked Questions

Why can't I find my Personal Vault files using the OneDrive search bar?

For privacy and security reasons, Microsoft intentionally excludes files stored in the Personal Vault from standard OneDrive search results. You must manually open the Personal Vault folder to view its contents.

Can clearing the app cache delete my Personal Vault files?

No, clearing your mobile app cache will not delete files stored in your Personal Vault. However, it may cause the app to temporarily lose sync with the server, making the Vault appear missing until you sign back in and let it refresh.

What should I do if my Personal Vault is missing on both mobile and web?

If the Personal Vault is completely missing everywhere, ensure you are signed into the correct Microsoft account. Also, check the Recycle Bin for accidental deletions, and verify your Microsoft 365 subscription status if you are storing a large number of files.

How long does the Personal Vault stay unlocked on a mobile device?

By default, the Personal Vault automatically locks after 3 minutes of inactivity on a mobile device to ensure your sensitive files remain secure. You will need to re-verify your identity to open it again.
