    I think it is possible now (Public Preview) but you need to have a Hybrid Exchange scenario.

      In specific, check out the following statement in the subsequent link of the shared link:
      "But we have no plans currently to change the way EWS works on-premises, so using Graph for Exchange Online and EWS for Exchange Server on-premises is the current recommendation."
