The client side rules are held in C:\Documents and Settings\jtokach\Application Data\Microsoft\Outlook

(Obviously replace jtokach with the user's id)

The .RWZ file contains the client side rules. If you have several, open the reg to HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles

The profile listed under defaultprofile is the profile that Outlook uses automatically when starting, if you don't have manual profile selection enabled. Otherwise, match the name of the profile to the proper .RWZ file.

This file, along with the others in this dir can be copied to the new machine. However, if the new outlook profile has a different name, all of the files must be renamed to that profile name in order for Outlook to recognize them. Also note that if these files do not exist, outlook generates these files automatically with the proper names. Delete those and rename your files with those names.

Hope that's what you're looking for.
