Fw: S/MIME or PGP?

[Darren Augi]

Hello all,
 
I have recently been tasked with making recommendations for a secure
email solution for a large group with 500 users. I am trying to weigh
either S/MIME built into Exchange or Enterprise PGP 8.0. It is a Win2k
environment running Exchange 2000 and Outlook as a mail client.
 
Please try and elaborate on the pros and cons of each. What would you
recommend?
 
Thanks
