I am very frustrated, and this makes me not use outlook. What to do to have 
my other email mailbox unchanged? Thanks!

Are you saying that you have two computers but you want only one
computer to download all messages from the server while the other
computer should download the messages but keep them on the server
for other computer to access them?

If so, then you need to put a check mark around: "Leave a copy of
messages on the server".  To get there, try this on the machine
THAT SHOULD NOT DELETE ANY MESSAGES:


1) Open your outlook (if it is not open)
2) On the Menu bar, go to: Tools, Account Settings,
3) Select by clicking once) an account you want to change and
click on the change button just above it;
4) You get a dialog box open with all the basic settings of your
account but you want click on the button called: "MORE SETTINGS"
5) On the next dialog box, click on "ADVANCED" tab
6) Now on the next box,the last three lines are the ones you want
to deal with.  I suggest put a tick on the first line that says:
Leave a copy of messages on the server" and remove the ticks
against the other two.
7) click OK and click Cancel and you are done.

You probably only have one POP3 mailbox, because that mailbox is on the POP3
server, not on your computer. If two computers are accessing the same POP3
mailbox, you must do as "LD5SZRA" says. On both of the computers, mark the
client (MS Outlook) to "Leave a copy of messages on the server". On one of
the computers, set a rule to "Delete messages from the server after 'x'
days".
