title: MS Graph API: looking for ALIAS of user
body: <p>I've been playing with the MS graph api. Nice stuff. </p>
  
  <p>One thing keeps me puzzled, i can't seem to find the ALIAS of a user, in the users properties. The people search <code>https://graph.microsoft.com/beta/me/people?$search="123456"</code> gives me the exact right result. But none of the properties matches the alias field (<code>employeeID</code>, <code>userprincipalname</code>, etc).
  I know it's in there cause the full outlook client can dig it out...</p>
  
  <p>Any tips (probably I'm overlooking something very trivial)</p>
