OneDrive API connection is not working for my outlook365 account

Question

In my proyect, my users can sync their onedrive so they canuse their files within my application. I wrote the code and when i try and connect my personal hotmail account it works fine. I get access to the files in my drive no problem. BUT the problem is that whenever I try to connect my onmicrosoft.com mail account i get the following error:

error=invalid_client&error_description=AADSTS650053%3a+The+application+%27MyApp%27+asked+for+scope+%27Files.Read%2cFiles.Read.All%2cFiles.ReadWrite%2coffline_access%2cFiles.ReadWrite.All%2cFiles.ReadWrite.AppFolder%2cFiles.ReadWrite.Selected%2cUser.Read%27+that+doesn%27t+exist+on+the+resource+%2700000003-0000-0000-c000-000000000000%27.+Contact+the+app+vendor.%0d%0aTrace+ID%3a+3cf8783e-acf7-4f47-916f-93c8ca7fe501%0d%0aCorrelation+ID%3a+6d0f7eff-4eed-4bc6-bd5c-1765c67961f3%0d%0aTimestamp%3a+2023-01-31+02%3a52%3a39Z

I double checked my azure portal and the scopes are on the app. AND this only happens when I try to use my onmicrosoft.com account. My personal one works like a charm. And the code is the same for both cases, it is the same app, same request, same everything.

I think it may be a problem with the onmicrosoft account, but i found no documentation on the matter.

Any ideas?

Hi @Luis

I decoded your error message and found that you are using "," sign to separate permissions, which may be the cause of the problem. You should separate permissions with spaces, like this:

scope=Files.Read Files.Read.All Files.ReadWrite offline_access Files.ReadWrite.All Files.ReadWrite.AppFolder Files.ReadWrite.Selected User.Read
