Add-ins are disabled while creating a meeting in office 365 group calendar in outlook 2016

Question

I am following this Article to create a new meeting in Office 365 group calendar using Outlook 2016(on Windows 10), But all the add-ins are disabled in outlook 2016 native when using group calendar. The add-ins works fine in web outlook for group calendar and for regular user calendar in outlook 2016 native as well.

Our applications helps to create structured agenda for a meeting but since the add-in is disabled we cant use the app in group calendar using Outlook 2016 native. Here is the screen shot.

This used to work fine earlier, Do we need to enable some settings so that these add-ins and enabled or is it not supported any more?

Would appreciate if someone can points me to the right direction here.

Answer 1

Add-ins in shared mailboxes are not supported. The fact that you are able to see them in OWA is a bug, since they only work partially (EWS and REST API do not work).

We plan to make the experience consistent with outlook desktop and the fix is on our backlog. The fix is going to be that, for shared Mailboxes, Add-ins will not show up in OWA as well.

We track Outlook add-in feature requests on our user-voice page. Please add your request there.

Feature requests on user-voice are considered when we go through our planning process.
