E-Discovery of remote PST files

[Dave Koontz <dkoontz () MBC EDU>]

All, our legal counsel are trying to comply with a legal request to turn
over all email communication campus wide regarding an individual over the
last couple years.  We do not archive messages, and the vast majority of our
users pull their email via POP3 to Outlook where those messages are stored
on their local PC.

Are there any tools you can recommend to remotely scan users PST files for
specific messages, and hopefully pull those messages out, or foward them off
to the administrator?

Obviously, we will have to come up with other methods for Mac users or those
using different email clients, but the vast majority are Outlook users... so
any help there would be greatly appreciated.  It will take forever to visit
hundreds of PCs.
