    Hello,
     
    Could you please confirm if the shared mailbox is Exchange Online (part of Microsoft 365 cloud). This action only supports shared mailbox created in exchange online. If the shared mailbox is created in on premise or hybrid setups often block REST API for mailboxes.
     
    Thank you.
