Zarafa enables users to work with mobile devices using different technologies. You can use ActiveSync-compatible devices via Z-Push and BlackBerry devices using the BlackBerry Enterprise Server (BES) to synchronize email, calendars and contacts.
You can find the latest compatibility list here.
Z-Push is an open-source ActiveSync implementation that synchronizes email, contacts, calendar and tasks in Zarafa. Zarafa cooperates with several other vendors on this dominant open-source ActiveSync compatibility platform. The platform has enabled Zarafa to set the standard on open-source ActiveSync compatibility. As a result, customers get better software thanks to our use of early adopters’ feedback on new business handhelds.
All devices using the ActiveSync standard are compatible, including iPhones, Android OS phones, Windows Mobile smart phones, Palm Treos and more. Zarafa supports the following key features:
Please check the Z-Push website for more information and downloads.
BlackBerry devices are integrated over by using the BlackBerry Enterprise Server (BES) or BlackBerry Enterprise Server Express (BES Express). The MAPI compatibility enables Zarafa to emulate Exchange behaviour and therefore be fully compatible with the BlackBerry.
You can download the Zarafa BlackBerry integration package on www.zarafa.com/blackberry. The BlackBerry integration is compatible with the Zarafa Professional and Enterprise editions.
