    Hi @Rising Flight ,

    Actually you can't modify the remote mailboxes permission from the on-prem EMS. It's located in the cloud and you could only use Exchange Online Powershell to modify it(also online Admin Center).

    You may receive a error said object not found on DC if you gonna try to run Add-MailboxPermission. And also there are no cmdlets like Add-RemoteMailboxPermission.

    You could find all cmdlets here:
