Z-Push (presumably Z is for Zarafa) is a FOSS implementation of the Microsoft Exchange ActiveSync protocol which is used to synchronize email, personal contacts and other items between a central server and a mobile device.[2]

Z-Push enables any PHP and non-PHP based groupware package to become fully sync-able with any ActiveSync compliant device with an appropriate backend.

Currently, Z-Push includes four backends: the IMAP and the Maildir backends for e-mail synchronization, the vCard and the CardDAV backends for contact synchronization, CalDAV for calendar synchronization, stickynotes for Sticky Notes Synchronization and one for the Kopano and Zarafa package which is sold by allowing full synchronization of E-mail, Calendar, Contacts, and Tasks.[3]

There is also a 3rd party project that implements a Zimbra Backend, allowing Z-Push to be used with a ZCS server (Including opensource edition).[4]

Since version 2.3.0, released in July 2016, significant performance improvements have been achieved, as well as significantly lower memory usage. Connecting to Outlook 2013 and 2016 via EAS is also officially supported. With the optional Kopano Outlook Extension (available only for paid subscribers of Zarafa/Kopano), additional Outlook features are enabled such as Out of Office replies and opening of shared and public folders.[5]

The future sustainability of the Z-Push project was in question after Kopano (formerly Zarafa) announced that they would no longer be supporting the project.[6] Z-Push now has a new maintainer from the community for future support of the project.[7]
