The Windows Live Calendar Team has announced the availability of the Microsoft Office Outlook Connector 12.1 Beta - which allows you to sync your calendars on Windows Live Calendar (calendar.live.com).

Download: Microsoft Office Outlook Connector 12.1 Beta

The Microsoft Office Outlook Connector is designed to sync your Windows Live Hotmail mailbox, Windows Live Contacts, and calendars in Windows Live Calendar to Microsoft Office 2007 (or 2003). The Microsoft Office Outlook Connector will work with any Windows Live Hotmail account - as well as Office Live accounts or Windows Live Custom Domain accounts (domains.live.com). Not only do I have a Windows Live Hotmail account - I also have a custom domain that uses Windows Live Hotmail as well.

When I installed the Microsoft Outlook Connector Beta - my calendars that I have in Windows Live Calendar appeared in Outlook 2007 under "My Calendars". I could check each calendar that I want to view (whether it be all or just 3 as you see in my screenshot). I can add and remove events and those changes are then synced back into Windows Live Calendar and then synced to any other machine running Outlook and the Microsoft Office Outlook
