I can get the messages in a shared mailbox with the
https://graph.microsoft.com/v1.0/users/sharedinbox@address/messages
endpoint, but is there a way to find all shared inboxes the current user has access to? I could iterate over all users returned from
https://graph.microsoft.com/v1.0/users
and then attempt to the list the messages from each one and only count the ones that I have access to, but that's not feasible in a system with 1000s of users.
Is there a way to get a list of just the shared inboxes I have access to?
