CUA is a global Office option and not specific to Outlook. You can disable
this via the generic Office GPO template.
I'm not sure if you can do the same for the initials or that you can disable
it by the various FirstRunDialog regkeys that exist such as in;
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook
Set the value to "false" (without quotes)
