Outlook 2000 security update

This is a function of the service pack, I belive. I have provide more links on the subject since we also have this issue. I have not found a way around it either - it seems this is by design.

It may provide some pointers. There is one that involves replacing two of the Outlook Files - However this is something you would have to do at tour own risk.
