title: Microsoft Graph. Access OneDrive with application own identity
body: <p>In a mobile application we are generating some images that we would like to upload to the client's cloud.
  The client is using OneDrive For Business, with all the 360 suite (I have no more information about it yet).</p>
  
  <p>What we would like to do, is to be able to store the images in a OneDrive account, without the user having to sign in. All the documentation I found to authenticate to OneDrive includes an interactive sign-in process which we don't want:

  <p>I have found that for Microsoft Graph there is the possibility of using the app's  own identity to sign in (only REST), but it is not 100% clear to me that this authentication can grant access to OneDrive.

  <p>Since I am not familiar at all with Microsoft cloud infrastructure I would appreciate some info. </p>
  
  <p>Is it actually possible to access a OneDrive folder authenticating with the app's own identity? </p>
