How to hide an user on Exchange 2000

Hello Everyone.

I have created an user for information distribution that i would like to hide for all the people that is not authorized to send messages from this user, i’ve granted permission to 5 people to use this account but i cant find the way to hide it from the global address list.

I know there is a way that u can hide it, but that includes the people that has persmission to use this account.

What i would like to do is hide it from the global address list and that only the people with permission could see it.

Can that be done??????

Thanks in advanced for all your help..
