Want to synchronize your Outlook calendar with Google Calendar and your iPhone? With the right setup, all the synchronizing can happen automatically and within an instant behind the scenes, without your moving a finger.

Enter an appointment in Outlook, and it will show up in your Gmail and iPhone calendars automatically. Edit the event later in Google Calendar, and the changes will be reflected in Outlook and on the iPhone instantaneously. Later, on the road, delete all commitments for the next 10 days — and they'll be gone from Google Calendar and Outlook right away.

Now, in 10 minutes much rather than days, set up Outlook synching with Google Calendar and iPhone Calendar.
