adam (hope that is your name [Smile] ),

One thing I noticed immediately when I saw your REG extracts is the word adam. Any registry merges/changes should not be that specific. You will probably want to have a look at the following:
Copy a shortcut to the Desktop, Start Menu, etc.

We have pretty fine list of FAQ too at:
KiXtart FAQ & How to's

Also, with your changes to -
(1) "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer"

Looks just like a policy. [Smile]

(2) "HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Security"
Is OL 2002 or XP all you have in the work place? Did you get a chance to look at -
Outlook/Exchange Configuration

This has great deal of research put into configuring and setting up Outlook.

HTH,

Kent
