Enable Google Sync via ActiveSyncPrint
Google Sync lets your users synchronize their mail, contacts and calendars to their mobile devices. This means that your users will have access (viewing and editing) to their inbox, address books and calendar events at any time. They can also get alerts (sound or vibration) for upcoming meetings and incoming messages.

When you enable Microsoft Exchange ActiveSync © support for Mail, Calendar and Contacts, your users will be able to utilize Google Sync for iPhone and Google Sync for Windows Mobile. These services are still in beta. Please consider the known limitations in advance.

If you'd like to enable Google Sync for your domain, follow these steps:

1.In the Service settings section of your Dashboard, click Mobile.
2.Select the checkbox next to Enable Google Sync.
3.Click Save changes.
This feature is currently available only in the Next Generation version of the control panel.
