I have an issue with Android phones and MobileSync. I am running Zimbra version 6.0.10_GA_2692 Network version on SuSE 10 64 bit system. I have a mixture of mobile devices. I have Window based phones, Apple based, and Android based. The Window and Apple based phones work without incident. This tells me that Zimbra is configured and operating more or less correctly. My Droidx phones running Android 2.2.1 will sync mail without a problem. They will show calendar events that are initiated from the Web interface, and they have uploaded contacts from Zimbra, but no calendar or contacts from the phone will download back into Zimbra. I have set the phones to sync with corporate sync and they seem to setup okay, but as explained only work half way. Any ideas?
