I seem to still be able to publish my free/busy information for people outside my organization to view via Outlook.com (not Office.com), which seems to work fairly well. Perhaps this only applies If you are using Outlook with an Office 365 (or Exchange) account?
For those that might not realize there may be additional options, it could be good to add a note that clarifies what external calendar publishing Microsoft does still support.

This page is specifically about the old Office.com service that was introduced with Outlook 2007 and discontinued. With this service, you could publish a calendar in a pst file and share a link to it - the recipients needed to open the link in a calendar program or subscribe to it in Hotmail or Gmail.
Exchange and Outlook.com accounts can share calendars with others (using methods specific to each account type) but pop3/pst users need to use a calendar service or WebDAV server to publish their calendar.

You can use icalx.com or keepandshare.com to publish from outlook. icalx only seems to display free/busy details, though.
