Google Sync uses Microsoft® Exchange ActiveSync® to let your users synchronize their Google Apps mail, contacts, and calendars to their mobile devices. They can also set up alerts (sound or vibration) for incoming messages and upcoming meetings.
Google Sync is enabled by default on Google Apps domains. Google Apps for Business, Education, and Government domains can enforce security policies on Google Sync devices. To learn more, see Google Apps Mobile Management.
Starting January 30, 2013, users, other than paid Google Apps users, won’t be able to set up new devices using Google Sync. iPhone and iPad users should see Sync Gmail, Calendar and Contacts. Other users should see our sync site for instructions. You can also consult with your device carrier or manufacturer for how they recommend to sync with Gmail, Google Calendar, and Contacts. Google Apps for Business, Education, and Government customers can continue to set up new devices with Google Sync after this date.
What do I need to do if I’m already using Google Sync?
Nothing! Existing users can continue to use Google Sync on their current devices.
