Having email in two locations

Does any one know how to configure microsoft outlook 2000 so that emails can go to a local (pst) location on the workstation and also keep a copy on the exchange server? I need this so when i take my laptop (workstation) out of the office , I can read emails (Offline)that i did not get a chance to read at the office. I’ve looked at microsoft article KB253490 & KB195718.
