Office 365

Hi,
I set up Office 365, but i can’t access anything on our sharepoint drives.
Find files and Folders activity always gives “AccessDenied” error. Also even tho i selected authentication with interactive token, the authentication window wont show up, just the error from find files and folders. I made the setup in Azure as it described in the docs.uipath page. Is there a sharepoint specific setting maybe which i have to enable before i can automate with uipath?
Thank you
Marci
