Use Exchange 2010 CAS for 2013 Mailbox

    Question

  • I've added an Exchange 2013 Mailbox and CAS role in our network, and then move the mailbox database from 2010 to 2013. However, it make the OWA move to Exchange 2013 CAS that I haven't publish on Internet yet.

    Can I use Exchange 2010 CAS server for OWA instead of Exchange 2013 CAS?

    Thanks

    No, Exchange 2010 can't proxy requests to Exchange 2013 so you will need to publish your Exchange 2013 to the Internet for users to get external access.
