I just learned of an update available for Outlook 2007 that fixes a couple of issues:

  • Search results returning private calendar items
  • Performance when using large .pst or .ost files

I have to confess - I don't personally care about the search issue so much, but I'm one of those pack-rats who has a VERY big .OST file (Outlook in Exchange "Cached mode" uses that file) due to the number of e-mails I've left (sorted or otherwise) in my mailbox.  Outlook seemed fine to me, but I'll take all the computer performance boosting* I can get!

HERE is the KB on the subject,
