title: Delete Ical event not working
body: <p>I am creating an ical event dynamically in my web application and when someone cancel the appointment on the application we are generating a delete ical event *.ics file to their email to remove the event in their calendar. </p>
  
  <p>Creating is working perfectly but when we try to delete the appointment we created it doesn't remove it from the calendar</p>
  
  <p>Creating Ical event code : </p>

  <p>When I click this file generated to remove the event that is already created it doesn't remove the event and sometimes it duplicates the event. </p>
  
  <p>The ical UID on creating and delete are the same. </p>
