After launching a sync tool for Blackberries, Google Calendar now offers a small utility for synchronizing events with Outlook. By default the synchronization is bi-directional, but you can change this when you install the utility or from the options dialog. The only significant drawback is that you can only synchronize your main Google Calendar, but a future update should remove this limitation. Google installs a small program that loads at start-up and sits on your system tray, while waiting for the next synchronization (the default sync interval is 2 hours). After synchronizing your calendar with Outlook, you can access it offline and synchronize it with your mobile phone.
