Changing "From" Header on received mail

[Bob Chmara]

I have a client who requires me to use their hardware and an email
address they provide. I often forward email I receive at the client
supplied email address to my own address so that I can refer to the
mail from my own machine. The problem I'm having is that all of the
mail that I forward has my client supplied email address as the from
address. That makes it more difficult to find it on my machine if I'm
looking for something sent by a particular person.

Is there some way I can edit the From header on received mail so that
I can change it to the address of the person who sent it to me at my
client supplied address? I'm using Outlook 2000.

Thanks,
Bob Chmara
