This appears to be a common problem, unfortunately. It seems to affect only existing .pst files, not new ones, so moving the data into a new ..pst might be a solution. If you have a retail version of Office/Outlook 2007, I strongly suggest that you file a support incident on this issue. Unlimited support for Office/Outlook 2007 is free for the first 90 days after activation. See http://support.microsoft.com/gp/vista_supoffnew for more information on this support policy.

I use Vista Ultimate and Office 2007. I have a custom form for adding
contacts.
I have a database with 7000 contacts.
I have discovered that a few searchs will not produce any results. Howeve,
i can see the contact on the phone list and access the record.
I have only discovered a dozen or so that it doesn't find. but i've only
checked 30 records.
I looked at the index status and it says it is up to date and indexes as I
add contacts.
Help! I have my data entry person checking if we have the person in the
database already before they add.
