When we right click on any email in OWA 2013, we get a context menu and by default it has some items like "Delete", "Flag", "Mark as read", "Move..." etc. I would like to add a custom item to this menu so that when I click on it it should open a new window.
I am using Visual Studio 2015 and C#. Can someone please share the information or knowledge about this, how can I achieve this.
What I have tried:
I was thinking to add ribbon because using ribbon we have done this in desktop outlook in 2010. But unable to do the same in OWA 2013 and Visual Studio 2015.
