Alright, so i'm having a little trouble setting this up how i'd like to have
it.
Normally outlook.pst is the default pst file. if I have email1, email2, and
email3, they share outlook.pst.
I need advice in how to maintain multiple email accounts, INDIVIDUAL of each
other, within one windows user account.

I can have mail rule filters separate mail from 1 into folder1, 2 into
folder2, etc.

I don't want to do it that way...

email 1 belongs to myself
email 2 my brother
email 3 shared between myself and brother, junk mail.

email1 goes to pst1 file.
email2 goes to pst2 file.
email3 goes to pst3 file
This is the goal.

where each pst file has it's own contacts, it's own junk mail folder, trash,
etc.

I created a new pst file, so i could see the default one, then the second
one, but when doing so, the new pst file only had 2 folders in it. there was
no section for contacts, there was no section for it's own junk mail. and
upon retrieving mail from my webserver, mail went to the default pst file.
not the newly created one.
