This seems to be a problem mainly with old .pst files. Moving all the data into a new store might help. If you have a retail version of Office/Outlook 2007, I strongly suggest that you file a support incident on this issue. This is the best way to let Microsoft know that there's a problem with the application. 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.
