title: Uneditable calendar events in O365 using graph API
body: <p>I'm importing lots of events into calendar in a calendar group in Office 365 on behalf of the user. These events shouldn't be editable by the user because I may overwrite changes that they make with further updates to these events. When using the graph API and retrieving an event I get told if the current user is able to edit the event through the <code>canEdit</code> property. Very similar to how an imported iCal file is shown to the user in O365, but the user can't change any of the events.</p>
  
  <p>Is it possible to mark a set of events as un-editable by the user through the UI using the graph API?</p>
