How to retrieve all users of a shared mailbox with Microsoft Graph API

Hi,

Reading the Microsoft Graph API documentation, I'm able to retrieve a shared mailbox and it's "owner" with:

https://graph.microsoft.com/v1.0/users/<ID>/?$expand=manager

or

https://graph.microsoft.com/v1.0/users/<ID>/manager

My question is: How can get all the other users of the shared mailbox?

    If by "users" you mean all the people that have been granted Full access/delegate permissions over the shared mailbox, the answer is you cannot do this via Graph. This is an Exchange admin operation, and the Graph currently has zero coverage for such. Use Exchange Online PowerShell instead (Get-MailboxPermission cmdlet).
