  • Awesome effective app. Responsive developer. This app is the best contacts sync for Zimbra full stop. It is sturdy and reliable. Developer responds effectively, and like wildfire, and is constantly improving it.



  • ... Better than original WordPress app. 🙂

  • Tested on Wiko Cink Slim and Zimbra of Web4all. No problem. This application delivers on its promise: rapid installation and configuration. operational in less than 1 minute. It allows sync contacts but mainly select address books and groups. What I could not do in push mode.


  • Works as advertised.... Works exactly as I needed it to. I had a persistent voice-mail notification that wouldn't clear without the use of this app.



  • I recomend for all zimbra administrators. This app makes easy the server monitiring, mainly because of the monitoring alerts.



  • Beautiful and functional! I use Zimbra Collaboration Server – Open Source Edition and this app connects and works flawlessly.

  • What a find! I stumbled across this app purely by chance but could have been happier. I run a one server Zimbra 8 installation for my office and ZadmiN works perfectly for all the quick day to day admin and the ability to monitor server status has been a big timesaver, allowing me to catch downtime before anyone else notices - even when I'm not at my desk



  • Manage with speed !! Faster access even compare to the originally zimbra web based admin control. Great app 🙂

  • Just what I was looking for This app looks soo good. Just top of the line. Works well with my fully up to date Zimbra 8.0.4_GA_5737 Samsung Galaxy S4 MF9. The Widget looks really clean. Even better I can simply tap a task on the widget an mark complete or edit it. By far the best Zimbra Tasks app. I wouldn't change a thing.



  • Application extra super and super lightweight.
