title: Open new meeting request from web application
body: <p>The easiest way I can describe what I want to do is this:
  I want the functionality of <code>mailto:</code>, but instead of opening a new email on the client's machine, I want it to open a new meeting request (ideally with certain fields already filled in, such as subject, attendees, etc.). At that point, the user can change the meeting request however they want (or just close it and do nothing with it).</p>
  <p>While it would be nice if the solution was pretty universal, my main concern is that it works with the Outlook clients (Windows, Mac, iOS, Android).</p>
  <p>I've looked into <code>webcals://</code> and <code>.ics</code>, and, from what I can tell, that's not what I really want as that is how to add meetings to calendars that have been created -- I want the current user to create the meeting.</p>
  <p>I'm aware that OWA (Office 365) has specific links you can use to do this, but some users still have mailboxes on premises.</p>
