title: Why does "Microsoft.Graph.User.AdditionalData" property contain manager information?
body: <p>Within the Microsoft.Graph.User object there is a field called &quot;AdditionalData&quot;.
  It seems this can hold many values, from telling if a record is a delta record to storing manager information.</p>

  <p>In this instance, it holds information on a users manager.
  It looks like it can hold multiple records however, so I am asking what is the best way to get data from this property, to ensure I get all values it might have.</p>
  <p>I am also unsure why manager information is in the AdditionalData property and not in the Manager property.</p>
