I have the Zimbra Network Edition, so I know it has ActiveSync.
However, when I try to configure a Zimbra account on the an Android device I always get an authentication failure. I tried different devices with different accounts. I know the username/passwords are correct because I verified it.
It has worked in the past at some point. I even upgraded to the latest version 7.1.2 but still no joy.
Any help would be much appreciated.
