Yes, that works fine. You need to know that you have to use Customise to place the button. You can submit this at ATN and let me know when it's ready so I can approve it. PM is OK. In general I'm a Lightning user, so it's not to terribly useful for me. That said, we have a long-standing issue that Lightning can only handle one attached event, bug 547754. Can your add-on save more than one? Or does Outlook only ever send one. For multipart/alternative, multiple text/calendar parts are imaginable.
