title: Is it possible to use AAD delegated permissions without physical user login?
body: <p>I would like an AAD app to act on behalf of a user, without requiring the user to login to authenticate himself.  E.g., I would like an app to be able to send an email from a user's account on the user's behalf programmatically using Graph API, but based on an event, and without user sign in each time to authenticate.  Is this something that is possible using AAD delegated permissions?  </p>
  
  <p>I cannot use the client credentials flow using application permissions, because my admin will not grant access to my app, so I am looking for a viable workaround.</p>
  
  <p>Thanks in advance!</p>
