    Hi Martin,

    The answer is no. Generally, you can open the ECP login page, but you will get error message after typing in the username and password. We suggest you install the mailbox role and try it again. If you still get the error message, please provide the screenshots of the full errors.

    Best Regards,

    Erick

    Hi Martin,

    Yes, you can try to see if you can move the mailbox from Exchange 2013 hybrid server.

    So I could try the 2013 server with a hybrid product key and then move the mailboxes from the 2013 server?

    Hi Martin,

    Thanks for the updates.

    You can try the steps using Exchange 2013 server to see if you can move mailboxes to cloud.

    For your question “Ultimately wouldn't that make the hybrid server a CAS server?”, that depends on your organization’s configuration, as you can install one Exchange 2013 server that has the Mailbox and Client Access roles installed. For your reference:
