The Outlook API tutorial is using this p2OAuth2 library for OAuth2 authentication purpose and further API calls. But can we change the authentication library to AppAuth-iOS? I have been using this for Google account integration and found it quiet useful and understandable.
I tried integrating AppAuth for Outlook, and login was successful. After that, I don't know how to implement the same for the APIs part i.e. for Calendar/Mail API.
