How do I add a button to this area of Outlook?

Question

So i have done some research and found how to add custom UI panels to various peices of the Outlook user interface via addons, however nothing I have looked at has answered this specific question.

I would like to add a new button to this area (blue arrow) along side these other buttons (pink arrow).

This menu appears both in the "People" context and when you hover over someone's contact picture in outlook.

Also if anyone has a good documentation on the various pieces of the outlook UI and the proper names for all the different panes, that would also be greatly appreciated.

Answer 1

The Outlook extensibility model doesn't provide anything for that.
