Question : Exchange 2003 Front-End/Back-End Info

Hey guys,

I have a couple of questions about Exchange 2003 Front-End/Back-End topologies.  We are very seriously considering moving to this format, as right now we only have a single exchange 2003 server.

When a message comes in from the internet, how is it processed?  Is it received at the Front-end server and relayed back to the back-end server to be stored?  Or is it just received by the back-end server?  Also, our clients connect (all using Outlook 2003) via POP3, SMTP, IMAP4, and what I call the "Exchange Setting" (both through LAN and RPC over HTTPS).  Am I correct in assuming that all the clients, no matter how they connect, connect to the front end server?  If my thinking is correct, then the clients connect to the front-end server, which basically acts as a go-between to fetch their emails from the mailbox store.  Now the real question is, for internal clients using the exchange setting in Outlook 2003, do they connect directly to the back-end server, or are they still connecting to the front end server (personally, I think the latter would make more sense)?

Any help you guys could give would be great.

On an Exchange server, the POP3 protocol is disabled.
You need to enable it in Services, then start it from within ESM.

As you have found a username combination that works, I would suggest trying it with a real POP3 client and see what happens.
