Perhaps you have a particular View setting, eg Unread mail or 7 days?

I recently started using Outlook 2003 after years with Outlook 2000 . I (
have XP SP2.) I will sometimes quickly look through my Inbox's new email,
briefly glancing at each one in a lower pane. Then, I will go back and
begin
complete opening them to read in detail - maybe answering one even.

A few times I have returned to the Inbox to find emails that I KNOW were
there, missing!

I've searched high and low and can't find them. Where can they be? I know
I
didn't delete them - anyway, Deleted Items is empty.

Any ideas? Regards, Denny.
