Hello All, A co-worker, the current Exchange admin, has stated that when the OWA client is used on our LAN that it establishes a connection directly to the mailbox store (as does Outlook) as well as to the front end server, and therefore the OWA should not be used as mail client on our LAN. 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.
