Nice article.

I have a question though. "Any Exchange 2016 Mailbox server will always proxy the client’s request to the Mailbox server that hosts the user’s mailbox database", does it proxy to the CAS component or the Mailbox component of the destination server incase of

Unbound model.


In 2013 "6.CAS proxies the request to the Mailbox server hosting the active copy. ", it doesn't matter though, still wanted to know.


In similar grounds Ex2013 CAS to Ex2016 proxy will be thru what and vice versa. As I have read its more compatible in doing that.


In Ex2013 ->Ex2010 it will be proxy but through CAS2013->CAS2010->MBX2010
