This video shows how whereyougonnabe can be integrated with Google Calendar using an iCal feed. In theory this should work with other calendar software which can publish an iCal feed (including Outlook), and over time we will test a greater range of calendar systems, but at this time our testing has focused on Google Calendar. There are also tools available to synchronize other calendar tools, including Outlook, with Google Calendar, so this is another mechanism that can be used to synchronize Outlook with whereyougonnabe.
