Support the discoverability of Shared Mailboxes
It seems that Outlook REST APIs is providing new scopes and the possibility to request the shared mailboxes. See this question on StackOverflow http://stackoverflow.com/questions/38616499/what-is-the-purpose-of-the-new-read-user-and-shared-mail-delegated-scope-in-az/38626322?noredirect=1#comment64649553_38626322
The problem now lies in the fact that we cannot "discover" the shared mailbox for the end user. It means that you cannot create an application that show all the shared mailboxes for an end-user because we do not know the name/id for them.

Thank you for this feedback. We are aware of this. We are not actively invested in this right now. More votes would help prioritize this. ^JT

I was having the same problem and the suggested solution on Stackoverflow http://stackoverflow.com/questions/38347554/list-shared-mailboxes-in-office-365-via-rest-and-javascript was to build some webservice which would query the shared mailboxes via PowerShell. I don't like this solution, but it is the only one I've come across so far.... apart from buildind a service on the EWS Maanged API.
