Z-Push is an open-source application to synchronize ActiveSync compatible devices such as mobile phones, tablets and Outlook 2013 and above. With a history of almost 10 years of successful synchronization with multiple backends Z-Push is the leading open source push synchronization.
Z-Push can be easily installed using our package repositories, see the install instructions for more information.
Please see the Z-Push Wiki for contribution information.
Since the future of Z-Push is unclear (https://forum.kopano.io/topic/3908/kopano-roadmap-2021/36), the intention of this fork is to fix issues and - if possible - improve the contributed backends (IMAP, CalDAV, CardDAV, etc.).
