Google is dropping consumer support for the Exchange ActiveSync protocol soon as a part of a “Winter Cleaning,” the company has announced. As a replacement, Google is recommending CalDAV for calendar, CardDAV for contacts, and IMAP for email — though obviously iPhone owners will also likely use the new Gmail app for that. The move isn’t entirely unexpected, Google has been updating its help pages to deprecate Exchange ActiveSync recently, leading us to speculate that it would be dropping support.
This was to be expected. When Google announced CardDAV support some months ago the first thing I did myself was get rid of the ActiveSync protocol. Now that CardDAV is fully tested and operational it is time to migrate the rest of the world. Google will not force current ActiveSync users to migrate with their current devices, but future devices will not be able to use it anymore.
Google will still support ActiveSync for Google Apps customers. Although my question would be why? Everything works through IMAP, CalDAV and CardDAV as open protocols instead of the proprietary ActiveSync. The only reason I can think of is that they don’t want to force big paying customers to change their support and processes.
