We had already set all computer to delivery location on local pc. But how to
use the cached exchange mode? What is the step? Setting in outlook?

Cached Exchange mode is usually the default, but you can't have mail delivered
to the a PST on the local PC. You must change it to the Exchange mailbox. In
Outlook, click ToolsE-mail AccountsNext. In the "Deliver new e-mail to the
following location" drop-down at the lower left., make sure it says "Mailbox -
username", where "username" is the display name of the person using Outlook.
Select the Exchange account in the pane at the top and click Change. Make
sure "Use Cached Exchange Mode" is checked. Stop and restart Outlook. Now
click File, then Cached Exchange mode. Make sure the check mark is next to
Download Full Items.
