Retrieve list of shared mailbox using Microsoft Graph PowerShell SDK.

Question

Iis it possible to use Microsoft Graph PowerShell SDK commands to list the shared mailboxes of the tenant.
I have tried get-mguser and in the insights class I found the shared attribute, but it seems to have no value.

Does anyone know of a method?

Hi @David Gómez ,

Presently, there is no Microsoft Graph API or Microsoft Graph PowerShell SDK available to list the shared mailboxes of an user. You can submit a feature request idea using this graph developer support link, which will be monitored by Microsoft team and make the enhancements to Microsoft Graph APIs. I will also upvote for you.

However you can use Exchange Online PowerShell script to achive this requirement and please find the relevent powersheel command and documentation links below :

Get-Mailbox -RecipientTypeDetails SharedMailbox -ResultSize:Unlimited | Get-MailboxPermission | select identity,user,accessrights  | where { ($_.User -like '*@*')   }
