On January 4, 2013, we’ll be shutting down several less popular Google Calendar features. You’ll be unable to create new reservable times on your Calendar through Appointment slots, but existing Appointment slots will continue working for one year. In addition, we’ll discontinue two Calendar Labs – Smart Rescheduler (we recommend Find a time view or Suggested times as alternatives) and Add gadget by URL. Finally, Check your calendar via sms and Create event via sms (GVENT) – U.S. - only features for creating and checking meetings by texting information to Google – will be discontinued today, as most users prefer mobile Calendar apps.
If you have any questions about this change or any other Google feature, contact the ITS Help Desk at firstname.lastname@example.org.
