Windows only: If you need to use both Outlook and Google Calendar, free sync utility KiGoo makes the process completely painless. KiGoo displays your Outlook and Google calendar side by side or overlays them to see all your appointments on a single calendar. Changes you make in either Google Calendar or Outlook appear quickly in both. You can manage your Google Calendar entirely from within Outlook if you desire—creating, modifying, and deleting appointments. The same synchronisation you get with your calendars applies to contact lists, too—KiGoo can move contacts between Outlook and Gmail or create a master list of contacts from both.
Google Calendar has added support for the CalDAV standard, opening up a realm of syncing possibilities for business users and webapps. Right now it’s somewhat limited, with a few known issues, but the big news is that it’s now possible to sync your iCal and Google Calendars without any third-party software. As the Google Operating System notes, however, it’s not an entirely simple process to hook the two up, so a free option like recently-made-free CalGoo might still be the best option for anyone who doesn’t enjoy fiddling.
