Publish a calendar on Office Online - Outlook - Microsoft Office OnlineDon't bother. They've messed up their security certs so badly Firefox and Safari/iPhone fight hard to stay away. It all smells abandoned; so much for Microsoft's Office in the Cloud strategy.
... You can use the Microsoft Office Outlook Calendar Sharing Service to publish and share and calendars on Microsoft Office Online with other people. You have control over who can view the calendar and who can remove the calendar at any time....
I think this initiative was overtaken by the Outlook Connector for Windows Live.
Update: Nope. Outlook Connector just displays Windows Live calendars in Outlook; they can then be edited in either environment. It doesn't get Outlook calendars to Windows Live.
