While there are several methods for syncing Google Calendar with Outlook or a Windows Mobile device, they tend to involve adding new software to the mix. Download Squad reader Dan sent us a nice tip for anyone who's not looking to synchronize calendars, but simply wants to use Google Calendar within Outlook.

All you have to do is right-click on the calendar tab in Outlook, click on Properties, and then go to the Home Page Tab. Check the button that says "Show home page by default for this folder," and then enter http://www.google.com/calendar. That's it. Now when you click the calendar tab in Outlook you'll see Google Calendar, and you can update it through Outlook or through any web browser when you're on the go. However, this method won't let you synchronize your calendar with a PDA--all it really does it replace Outlook's Calendar with a web page. If you uncheck this option, Outlook will revert back to its grayscale calendar and all your old appointments will show up again.
