There are some rules you can make in Outlook that only work client-side.
This seems to be true in all Outlook versions up to and including XP.
And even if you use exchange server, and have your delivery location set
to the Exchange server. 

On my own mailbox, I use Outlook XP with all service packs and connect
to an Exchange 2000 server. I have 24 or so rules, and some of the
simple ones (which just look at the sender address) work server-side,
when outlook is not open. However, every time I open Outlook, I get a
"runnning rules on new messages" dialog box. So something is happening
client-side. I'm sure it's documented somewhere which types of rules
cannot run on the Exchange server, but I haven't been able to find it.

So, I figure you MIGHT NEED the filter time even if you're using outlook
in an Exchange Server environment, even if you user the Exchange server
as your primary storage location. Only fairly simple Outlook rules run
at the server level.
