1. I have installed Office 2003 as administrator on the
local machine
2. I have logged in as a domain administrator (user x),
performed the initial setup of mail accounts etc as this
priviledged user, then logged off from Windows.
3. I have removed this user (user x) from the domain admin
list and then logged back in to Windows and try and start
Outlook 2003 and receive the above error message. No error
number or further information is presented in the dialogue
box (apart from the OK button).

The only thing that seems to fix it is making the user a
domain admin or a local machine admin, neither of which I
want to do especially considering all other applications
seem to function normally. It appears as though this is
some sort of permission issue however I'm lost as to where
to start. Any suggestions appreciated.

TIA
