All my posting about Outlook 2007 has come in handy! On Saturday, Kevin sent me this link, and today Justice sent me this one. Both point to a hotfix from Microsoft for Outlook 2007:
This update fixes a problem in which a calendar item that is marked as private is opened if it is found by using the Search Desktop feature. The update also fixes performance issues that occur when you work with items in a large .pst file or .ost file.
I have installed it on both my main computers, but haven’t really had a chance to test it yet. This thread at Neowin.net looks positive though. Here is the KB article, and the download page. Enjoy!

I like the way they mention the performance issue as a "by the way" add on.
I’ve installed it and will see how it goes after a reboot later.
Yeah the "afterthought" is bad enough, but I think it’s worse that they imply the issue is with the user and not the application. It shouldn’t matter how big my PST file is or how I choose to use Outlook! Certainly apps are designed for a specific purpose, but something as massive and widely-used as Outlook needs to do a better job of adapting.
