title: Creating a new email from an Excel Add In
body: <p>I have an excel add in that I'd like the user to be able to send an email from.  I could use mailto: but it's likely the amount of content to send would exceed the limits for that.  </p>
  
  <p>Ideally, it would be nice if I could somehow invoke the local outlook client with the content in a similar way and then allow the user to have the final say on hitting send.  I suspect this isn't possible though?</p>
  
  <p>Failing that I guess I'd need to use the Microsoft Graph API which adds a lot of unnecessary complexity to it since I assume I would then have to sort out the authentication along with the UI for sending the email.</p>
  
  <p>Any thoughts anyone has that might help simplify this greatly appreciated.
  Thanks.</p>
