Removing the HTML 'Private Address' option
We are phasing out the ability to share calendars using the private address. As of September 27, 2011, you are no longer be able to view someone's calendar using the HTML private address.
Previously, embedding or sharing a calendar using the HTML private address made the calendar accessible even if it wasn't publicly shared, or even after you'd decided to restrict viewing access in settings.
We've removed the ability to view a calendar using this method in order to provide improved security -- now, a calendar owner will need to make a calendar public or explicitly define who a calendar is shared with, and it's easy to change or revoke viewing access for individuals or groups.
To view calendars now:
- Ask the calendar owner to make the calendar public (or shared with everyone in your domain if you're using Google Apps for your Domain). You'll then be able to view the calendar using the same URL.
- Or, ask the calendar owner to share their calendar with you (you must be a Google Calendar user in order to view it).
