As of the date of this post there is no easy way to sync Outlook 2010 with google calendar. This is fairly normal for a beta release, but in the meantime there is a workaround. Since Outlook can read iCal and Google read the iCal format you can do this with the following:
- Go to your calendar details page in Google Calendar (Settings link at the top of the window then Calendars and then click on the calendar name).
- At the very bottom of thepage are two sets of icons one public & one private.
- Right click the iCal icon from the private and select copy URL.

- In Outlook, go to your calendar and click the Open Calendar button and select From Internet.
- Paste the URL in the text box and click OK.

And voila!
Note: This will only work one way and is not a sync. Outlook will pull down the entries form the Google Calendar. This is a relatively good work around until Google updates their sync tool for Outlook 2010.
