After some recent experiments in connecting by Outlook calendar to my Google calendar, I managed to import a couple years worth of reoccurring appointments into my Google calendar. To my surprise, these were not imported as reoccurring appointments, but rather as individual appointments. To my further surprise, there was no way (at least that I have come across) to delete multiple appointments sharing the same property–i.e. title. This meant I would have to delete each calendar event one at a time. Crap.

This code would need to be run in the Google Script editor by hitting the play button. You would also need to be logged in to the calendar which you are trying to modify. Also note that this is not meant to be a simple UI….as in, there is no undo button.
