Enable Add-ins when creating Appointments in Group Calendars
It should be possible to use Add-in while creating meetings in group calendar. This works in Outlook Web but not in native.
Our applications helps to create structured agenda for a meeting but since the add-in is disabled while creating meeting in group calendar, we cant use the app in group calendar using Outlook 2016 native.
Currently in Outlook native Add-ins are not supported in shared mailboxes this is mentioned in details in the below Stack Overflow question.
Currently, group boxes don't support Outlook add-ins. It would be really useful if they would support it.
I was following this guide to create a group box and reproduce this behavior

This is a really important feature !
Note: I understand (EWS and REST API does not work) in shared mailboxes currently but we are happy with this limitations as well. At least the basic add-in functionality works out of the box.
