All Outlook does is to exchange (send and retrieve) your messages between
your pc and your mail server(s) - which may be your ISP's mail server and/or
one or more other domain mail servers.
If you're not seeing your incoming mail when you access the server directly,
it's probably because your Outlook settings are telling it to delete mail
from the server as soon as you've downloaded it.
Here's what to do in Outlook 2002 - I'm sure it won't be too different even
if you're using a different version:
Outlook Main Menu >- Tools >- email accounts >- email view or change -
(select account and press "Change") >- More settings >- Advanced >- Check the
box "leave copy of message on server" then decide whether you want messages
to be deleted from the server after "x" days - or to stay there until you
delete the particular message in Outlook - by checking the appropriate boxes.
Remember, the longer you let mail stay on a server, the more space you will
use at that server - and if you exceed your storage limit you may lose
incoming messages !
I find "remove after 10 days" and "Remove from server when deleted in
Outlook" works well for me.
