I have the same problem since a while. I have tried everything to solve this problem, but nothing works.

Hi I have the same problem but interestingly I have Onedrive installed two different phones. I have no problem with files in my Vault on my Galaxy S 22 running Android 14. I cannot access my Vault files on my Galaxy S8 running Android 9. Does this help. The issue with the S8 appeared yesterday, up to thenit App was working fine. Chris

I have a Pixel 6a with Android 15. I noticed just now that there was an Android 15 update on 5 April, and the fault appeared when I tried to access OneDrive a couple of days after that. Suspicious? MS closed my case saying that many users had the problem, they were working on it but couldn’t say when it would be fixed.

Hi Thom

I received the following reply from MS support:

Hi Luigi,

Thank you for your clarification.

We sincerely apologize for the misunderstanding in our previous communication. You are absolutely right that your intention was to close the case after receiving the ETA, not before. Thank you for pointing that out.

As requested, we will keep your case open and continue to monitor it. At the moment, we do not have an ETA available yet, but rest assured that our engineering team is actively working on a resolution.

This case might be automatically closed by our server due to no response or no communication from both sides while we receive updates from the team. In that case, you can file another ticket and mention the current case number 7072847889 and we can continue where we left off.

Your patience and understanding in the meantime are greatly appreciated.

Kind regards,
Sunil K.
OneDrive Support Team.
Working Hours: 07:30 AM – 05:00 PM IST.
They don't know how to resolve our issue
They wrote that their engineer team are studying the problem 
But They were studying since a month ago and the support doesn't know ETA to resolve this issue!
It's incredible!
We pay in advance the service and they create and have no idea to resolve it!they don't give any solution and close the ticket!
