Marcel, Thanks. I did not state in my post that the OWA URL is to the front-end server only.

This said the reality is the same. The user uses OWA or outlook to connect to the front end server on the LAN. The front end server connects to the back end server where the mailbox stores are and you're up and running. If OWA is running on the same machine as the front end (In most cases this is true) then you could say that OWA is directly connecting to the mailbox store on the back end, but the true connection is still on the front end server and the user running the webclient to access OWA is never in direct contact with the mailbox store on the back end server.

When I use NETSTAT and Exchange System Manager's log in's for mailbox store, I can not see this taking place. It appears that when using the OWA mail client on the LAN, the front end server brokers access to the mail store on your behalf, and no other connection is made to the mailbox store. We are running Exchange 2003/Windows Server 2003. We have a front end server (OWA server) and back end server with mail stores. As a newbie Exchange person, your seasoned observations and comments are welcome.
