I replaced my Outlook 2007 with Outlook 2010. Since I am using Google Calendar, I would like to sync my calendar with Outlook. With Outlook 2007 you can use the Google Calendar Sync application. After installing Outlook 2010 the synchronization of the calendar didn’t function anymore. While synchronizing you will receive the following error message.
Outlook 2010 is available for some time now, so I don’t understand why Google didn’t release a version of Google Calender Sync which support Outlook 2010. I searched the internet and found the following article on the Google Forum. The article describes how the replace the GoogleCalendarSync.exe with a modified executable. The modified executable can be found here.
Just close the GoogleCalendarSync application and create a backup of the current executable. Replace the current executable with the modified version and restart GoogleCalendarSync. Now you are able to synchronize your Google calendar with Outlook. As far as I have read the thread on the Google forum, this solution should work for 32-bit versions of Outlook 2010. The status for 64-bit versions is unknown.
