My company does not use outlook anywhere with Exchange 2007. We are looking to make the transition to Exchange 2013. When I cut-over from my 2007 CAS servers to my Exchange 2013 CAS server I believe the brokering happens through the legacy.<mydomain.com> name space by default (as long as I have configured this on my 2007 servers). For the reverse proxy to work to my Exchange 2007 Mailbox servers, do I need to have Outlook anywhere turned on?
Thanks
