Thanks for your quick reply.
I have tried this endpoint, and it seems to only work with files belonging to the user from whom my app have delegated permissions.
My case is:
- My app acts on behalf of user A (with delegated permissions)
- User B sends a Teams chatMessage with an attachment to user A
- Attachment is stored in the user B sharepoint/one drive
- Graph API (/shares/{shareIdOrEncodedSharingUrl}) returns an "unauthenticated" error
This exact same endpoint works for files stored in user A one drive.
It looks like I missed a permission but I don't know which one.
My app currently have these delegated permissions:
- Chat.ReadWrite
- Files.ReadWrite.All
- Sites.ReadWrite.All
Can you help me ?

We are checking on it internally with the engineering team. We will keep you posted once we have an update.- Meghana-MSFT
Enigineering team has asked for the request-id for the call that fails with unauthenticated?
Below is the Teams observation -Since the linked thread mentions the scope is
Files.ReadWrite.All(required for cross-user data access) my only other guess would be that the token is for the wrong audience, but if all users are on the same domain that wouldn't explain why user a and user b have a difference.To check further request-id for the call that fails with unauthenticated is needed.
Unfortunately, property "request-id" is not included in the API response.
The exact returned json is:
{
"error": {
"code": "unauthenticated",
"message": "The caller is not authenticated."
}
}
Users A and B belong to the same tenant/domain.If I remove the Bearer token when sending request, I get this error message:
{
"error": {
"code": "InvalidAuthenticationToken",
"message": "Access token is empty.",
"innerError": {
"date": "2022-12-15T13:47:55",
"request-id": "7906a249-f925-4bbf-b4c4-e2cbd1aefd67",
"client-request-id": "7906a249-f925-4bbf-b4c4-e2cbd1aefd67"
}
}
