We are using the outlook 2003 SP3, we use the advance search in the
find, and key in or select the "sent from" box, and then click the find,
for some user like me, I can have the search result with exactly the
message I
needed, but for some users, nothing is returned.

And I just find that the only difference for those who can search and
those who can't search is that I 've cached the exchange folder and for
those who can't search is that they didn't cached the exchange folder. Is
that
I can't search in the exchange folder is I don't cached it?

It would be easy enough to test. Have one of those people enable Cached
Exchange mode and see if that makes a diference.
