In “Google Time”, the availability of ActiveSync for calendar and contact synchronization with iPhone, Windows Mobile, and other PDA’s is old news (announced on 09-Feb-2009).
Currently, the team at Horizon is prepping our contacts and calendars so that we can fully test the new features.
The big caveat is that starting up ActiveSync replaces all Calendar and Contact entries. As we juggle multiple calendar and contact lists, we are “cleaning things up” before we test.
I will post again in a few weeks with the results. In the meantime, feel free to share your experiences with ActiveSync and Google Apps Premier Edition
