Outlook to Google Calendar syncing is nothing new, Google already has a sync software for this.The only problem with that package is that it does not sync selectively; all information from my outlook goes on to Google Servers. This is something that will not go down well with the policy makers at my job. If only the software allowed the user to select the fields that need to be synced.
