Help on Exchange 2000 Administration

[shginfo]

I have trouble setting up an administrative user account to change Exchange user information.
I am wondering if I can give a user the right to manage my Exchange contacts via the Outlook address book.
E.g. I would like a secretary to manage my Exchange contacts without having to access the mainframe terminal or any remote control tool.
Could anybody give me advise?
Urgent!!

Thanks in advance...
