Support for invoking O365 add-ins in shared mailbox context in the new Web Outlook
We have been told that support for add-ins in shared mailboxes will be added to Outlook in Q2/Q3 of 2019. Thus, we have started rolling out support for shared mailboxes in our add-in too.
As part of this, we have noticed that the add-in icons are only rendered in the context of a shared mailbox element if the user is in the _old look_ of Web Outlook.
Since more and more people will be using the _new look_ as default, users should be able to invoke the add-ins via the new look too.
Please add support for rendering the add-in icons in the _new look_ of Web Outlook too in the context of shared mailboxes.
To anyone who wants a temporary work around: it is currently possible to open an add-in a shared mailbox context in the _new look_ by opening the add-in a personal mail box context, pinning it, and then navigating to a shared mailbox item.
I am not a Microsoft employee, but as per the latest community call (Sep 11, 2019) this seems to be in Preview. It will be released as part of 1.8 or 1.9 of the Outlook JS API (which is either November or early 2020 according to their expectations).
The above is based on the presentation given during the said community call.
This would be nice!
