To remove, or shut down Outlook express Microsoft 2000

How to remove it from control pannel, or to turn it off, without lossing the entire Microsoft Office 2000? I asked their support: can’t help, don’t know, very rude (after almost 2 hours staying on hold on the phone). It seems that I can either remove the whole Microsoft office 2000, then I don’t know how to re-install it back. Is there a better solution then this program, that I rarely use, as I mostly use microsoft works- it is similar word program, with less features.
P.S- I have Windows XP.
Thx, Lucy
