You don't say if you are in an Exchange environment, or using standalone POP
or IMAP accounts. This will determine the methods available to you.

Alternatively, get InstallRite from
http://epsilonsquared.com, and create a
change-tracking file for the differences between a default install and the
way you want it. Bear in mind that if this includes the .pst, running it will
zap any existing mail.
This is one of my main gripes with Outlook. Whilst all of the mail folders
are stored in a single .pst file, perversely the settings aren't in there,
but scattered through the registry and a number of other files in Application
Data. Thus there is no easy way to migrate an Outlook account from one
computer to another - Except perhaps for roaming profiles, which introduce a
whole raft of issues of their own.
This issue is one of the reasons many companies are going the OWA route for
general email access. Alternatively, with a client like Mozilla Thunderbird
which has a consolidated mailbox, you can achieve this amazingly simply.
