Ok, so a program on your PC is trying to access the Outlook address
book. Outlook is giving you a warning about that. You want to stop that
warning and /deny/ the other program's access to the Outlook address
book.
Surely the right answer is, to find out /what/ other progam is trying
to access the Outlook address book, and then stop that program doing
so. Perhaps it has an option to stop. Or perhaps it is a virus, in
which case, you should take steps to get rid of it.
Otherwise, it's a bit like asking: "My engine is emitting smoke, how
can I conceal that smoke?". The answer is, you don't conceal it. You
find out what is causing it!
