That's different. I've used mail systems with Exchange, with MS Outlook
and as far as I could tell, all my mail was kept on the Exchange server,
not locally on my peecee.
That's differnet. That's an Outlook option to fully download the files
on the computer instead of working live. Entourage doesn't use MAPI (it
uses WebDAV) and doesn't let you work live anyway. When you are offline,
you simply don't connect to the Exchange server at all in Entourage.
Working offline is still useful in a somehow similar way though. When
you are not connected to your network, Entourage can let you access the
local copy of your IMAP, Exchange (or hotmail) e-mails without
continuously attempting to sycnhronize with the server. Entourage simply
accesses the local copy of the e-mail stored in cache.
When you select "work offline", the status of the Exchange account
immidiately switches to "not connected" and you stop receiving new
mails.
Entourage's help even states:
You can use Microsoft Entourage to receive messages from any or all of
your e-mail accounts. For all accounts, you must be connected to the
Internet or a network and you must not be working offline (on the
Entourage menu, make sure that Work Offline is not selected).
You can even verify this behavior using a port sniffer like tcpflow,
tcpdump or even Interarchy (my favorite

). (I've had a lot of
Exchange problems and beleive me, I did explore all the aspects of it
that I could).
People who collect their e-mail from a POP3 server have the mail that
they read stored locally on their machine. Using a POP3 server is an
option in Entourage. IMAP is another option.
That's set up in a different way in Entourage. You can setup whether to
download the entire content of the e-mails or just the xxx first kb.
People who use POP3 usually send mail with SMTP. Documents they work
with are stored locally. Like Macsoup.
Absolutely. That's how POP works with the default options.
(I can see you use Macsoup for News. Macsoup is an offline news reader).
offline newsreader and also POP e-mail client

Very convenient for
managing discussion lists as well thanks to its unique way to display
the hierachy of who is answering to whom
