UPDATE: EAS support has been extended through December 31, 2013.
You may have seen a recent announcement from Google regarding changes to the Google Sync service used to connect devices to Google services (Google Sync utilizes the Exchange ActiveSync, or EAS, protocol from Microsoft to synchronize email, contacts, and calendar). We’re happy to share today that Google will extend their support for new Windows Phone connections via Google Sync until July 31, 2013 December 31, 2013.
At the same time, the Windows Phone team is building support into our software for the new sync protocols Google is using for calendar and contacts—CalDAV and CardDAV. These new protocols, combined with our existing support for the IMAP protocol for email, will enable Windows Phone users to continue to connect to Google services after July 31, 2013 December 31, 2013.
