Can not find contact that exist in the contact list

[Chet Guzel]

Hi Folx;
I have a few 1000s contact in my contact database. there are about afew 100
of them which outlook does not show when I do search. rest of the contact
are fine and ourlook shows them in the search results. I compared some of
the contacts that can be found by search with the ones that search can not
find. and there is not any difference. any ideas why ourlook search can find
some and can not find some?

Thanks
Chet
