Publishing free/busy info in Outlook 2007 (or iCloud for that matter)

As I ramp up my Outlook 2007 mad skillz (hah), I'm trying to figure out what I'm doing wrong when trying to publish my free/busy information to a personal Web server. I've been relying on a Microsoft Knowledge Base article to do it step-by-step. But step 3 refers to a "Look In" box that I'm not seeing in the Windows 7 version of Outlook 2007. I thought maybe I needed to map an FTP drive in Windows 7, and was able to do that, but it didn't give me access to any "Look In" box or provide any other path forward.

If you are an Outlook ninja and can tell me what I'm doing wrong, please send me a message or comment here. Now I'll go back to grumbling privately about the lack of free/busy publishing in iCloud.
