Sure; you modify the installation, via add/remove dialogue or direct from
Office cd to remove OL (set it not to run from PC)
However both Office 2003 & OL 2003 is fully compatible with Vista, any
problems you are having are likely caused by your installing Office2k and
then using the Office2003 cd to upgrade your installation. As Office2k is
incompatible with Vista / not tested on Vista and will give problems which
the upgrade may not have cured.
If you have any vestige of Office2k on your PC it should be uninstalled,
then use the Office2003 cd to repair your installation.

Is there a way of removing just Outlook, without removing Office 2000 and
2003 Update. Outlook is causing interference with Windows Mail on Vista.
