In this case, you can consider using the application permission.

In Azure AD:

  1. register a Web Application in your Azure AD.
  2. add “Read and write calendars in all mail boxes” permission enter image description here
  3. generate the application secret key

In your application, call Office 365 Graph API - create events by using application token.

http://graph.microsoft.io/en-us/docs/api-reference/v1.0/api/user_post_events

        var tmgr = new ApplicationTokenManagement();

        var token = tmgr.AcquireToken(Settings.ResourceUrlOfGraph);

        var api = new Graph.GraphCalendarAPI(token);

        JObject body = new JObject
        {
            {"subject", "Create from Office 365 API"},
            {"start", new JObject { { "DateTime", "2016-03-09T00:00:00"}, { "TimeZone", "China Standard Time" } } },
            {"end", new JObject { { "DateTime", "2016-03-10T00:00:00"}, { "TimeZone", "China Standard Time" } } },
            {"isAllDay", true }
        };

        var task = api.CreateEventAsync(body, "[email protected]");

        task.Wait();

You can find the complete sample here.
