good way to organize email

[Hobbes2006]

I use Outlook at work. I get emails from many clients.

Is there a good system that I can set up to organize the email by client and
subject matter and date?

There's 50+ people, so storing them in folders isn't very efficient, even
with message rules.

I dont know that anything would be very efficient, even using multiple
pst's.
Its much the same as trying to organise My Documents, or your default
doc.store, to do the same thing, with the same data.
