As of August 1, 2014 the Google Calendar Sync for Outlook will no longer be supported. This blog post is not a “solution” but rather a work around.
This assumes you have a Google Calendar and you are wanting to have your work Outlook calendar show up on your Google Calendar.
In your Outlook calendar choose to create a “new event.”
When setting up your event, type in your Gmail address into the “Attendees” section.
If someone adds an event to your calendar, you will want to open that event to share with your Gmail.
In order to add your Gmail as an attendee you need to forward the calendar event to your Gmail. This will add the event to your Google calendar.
