I have been using Outlook 2007 for the last 2 months with no problems except
that lately my "search" is not working correctly.
I have emails going back to 1999 in the Inbox, and for some reason, when I
try to search my old messages (using email address, subject or text within
the message), Outlook never finds anything, eventhough I can find them
MANUALLY if I scroll up and down.

With about 6,000 messages in my Inbox, this is horrible and time-wasting.
I have tried changin the search options (this is the little Search Inbox)
but to no avail! How can this be fixed that inside this box it finds/flags
any of my choices. I have also tried to use "Add Criteria", but it's not
helpful.

I never had such a problem with Outlook 2000, 2003 or XP.

Please advise!
