OneDrive Vault on Android.

The app has all the permissions and it stores and shows everything without any issues. BUT, when it comes to the personal vault, the android app is simply a s**t. I could even-with a lot of redoing steps and verifications- open the vault using a web browser (android). It is not an upload, authorization, connectivity, synchronization issue. It simply seems that I do not have a personal vault, and seems that I have never set it up before, which I also tried to do a couple of times, but it loops and never works.

And by the way, it is a hunt to find the MS OneDrive support channel...it always comes to these discussion boards.

Hello M,

Thank you for posting your question in the Microsoft Q&A forum!

I understand that you are having issue with OneDrive. I truly understand how you feel. Let me assist you go through this situation.

Please give these basic troubleshoot a try:

1. Update and hard-reset the Android client
   • Update OneDrive from Google Play.
   • Then: Settings > Apps > OneDrive > Storage > Clear Data & Clear Cache > reopen OneDrive and sign in again.
   • This fully refreshes the app’s secure storage and re-establishes the Vault token.
2. Re‑authenticate Personal Vault cleanly
   • Open OneDrive > Personal Vault > unlock with your second factor.
   • If prompted to “set up” again, complete setup and create the PIN/biometric. Several users report that re‑setup makes the files reappear (some even matched the phone’s screen‑lock PIN).
3. Disable battery restrictions for OneDrive
   • Settings > Apps > OneDrive > Battery > set to Unrestricted (or disable optimization).
   • Secure folders can time out or fail to refresh under aggressive battery management.
4. Switch networks & test a small upload
   • Try a different Wi‑Fi or mobile data, then upload a small image/doc directly into Vault from Android.
   • This checks whether the “refresh” error is network‑related and forces a fresh sync path.
5. Try mobile web as a temporary workaround
   • On the phone, visit onedrive.live.com, unlock Personal Vault, and verify files.
   • If the web shows content, the issue is almost certainly the Android app state.

Note: Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.

Quick check to avoid hidden blockers:

• Confirm you’re signed into the same Microsoft account on all devices.
• Ensure Authenticator/PIN/biometric are active and not failing silently.
• Verify storage isn’t full (OneDrive quota), as Vault operations can fail when at limit.
• One more thing, if you use Samsung Gallery > OneDrive integration, or other apps that write into OneDrive, keep their background access enabled; strict background limits can cause “refresh” errors in secure folders.

I hope this will help with your situation. Please feel free to reach back if you have further update or more questions.
