I partition my email in pst files for each year. I only open an old pst file if I want to search for a specific email. After upgrading to Outlook 2007 the "advanced find" does not work in these old files when I open them in outlook. Advanced Find alway gives empty result even if you search emails which you know is there. If I disable (uncheck all in instant search option) Advanced find works again. Anoying. Any idea what may be wrong?
