title: Creating Task Request using EWS and MAPI
body: <p>I am facing the problem of creating task request via EWS. However, still failing. The best I could create was messege which contains task as attachment. This message contains Accept and Decline button but the buttons are not clickable. Is there anything else what I need to set e.g. some MAPI properties?</p>
  
  <p>I know that there is no way to create standartly in EWS but Outlook must do it some way.</p>
