    Hi Robert,

    So according to this:

    As for your question "Do you create the hybrid server onsite and then connect your Office 365 Remote move to this hybrid server?", the answer is yes.

    Ultimately wouldn't that make the hybrid server a CAS server?

    Great.  Would I be best looking at doing this as an option to get the mailboxes into the cloud?

    Hi Martin,

    The answer is no. The Hybrid server will not tale over as a CAS server.

    Let me know if you have other questions.

    Regards,

    Hi ERick

    i think you misread my question. When I said Exchange 2013 hybrid server I meant a temporary Onsite install of exchange 2013 with a hybrid key and then this Onsite server takes over as a CAS
