SharedMailbox members (mailbox permissions) via Graph API
We are trying to get the members (mailbox permissions) of a SharedMailbox via Graph API. We do not see any Graph endpoint at the moment that can help us get this information. We are in the process of building a custom application where we need to be able to perform read and write operations of SharedMailbox membership/permissions. This functionality is certainly available via the exchange online powershell and I can imagine this being a critical functionality which is not yet available in Graph API. .

Weighing on this as well. Would be extremely helpful to read user membership on a shared mailbox via graph to show on dashboards.

As a general extension to this feature request, the ability to list/modify the permissions on Mailboxes and MailFolders (something similar to the permissions endpoint that is available to DriveItems) would be very helpful. This would allow Mailboxes/MailFolders to be shared with other users via the graph API.
