We have Exchange 2003, and running the Outlook 2003 client. Our users have
archive PST files on a File Server we have.

Now, if they keep the archive folders open on there PC (in the Outlook file
hierarchy, does Outlook continuously talk to the File Server to keep the
archive file/view updated, thus making our file server slow due to network
traffic from 200+ users?

As always, thanks in advance for any help
