A Microsoft file hosting and synchronization service.
Try this on the Samsung S25 first:
- On Android, go to Settings > Permission Manager > Files and Media.
- Select OneDrive and set it to Deny.
- Open OneDrive and try to open the file or Personal Vault item again.
- When prompted, select Allow or Enable permissions.
If Personal Vault itself is the issue rather than a single file:
- In OneDrive, select Personal Vault.
- Complete identity verification using the available method, such as text, email, PIN, biometrics, or Microsoft Authenticator.
- If Personal Vault opens but shows it is not up to date, close any files stored in Personal Vault and wait for sync to complete before locking it again.
- If sync is slow, increase the auto-lock time in OneDrive: OneDrive cloud icon > Help and Settings > Settings > Account > change the Personal Vault lock wait time.
Useful checks based on the symptoms:
- Personal Vault on Android locks automatically after 3 minutes of inactivity unless the auto-lock setting is changed.
- Personal Vault files do not appear in search results by design.
- Personal Vault is available for OneDrive home and personal plans, not work or school accounts.
If the problem continues on Android while access still works on the laptop, use Contact Microsoft Support from the support options, or on mobile open the OneDrive app and gently shake the device to contact support.
