I have been suffering from this annoying problem for a very long time, and the same problem was experienced even in Zimbra Desktop 2.0 Beta1 (I had uninstalled version 1 first).
Eventually I downgraded back to version 1.0.4 build 1833, and then also downloaded the latest iTunes (I now have iTunes 9.1.0.79), then disabled every option I could find in iTunes about communicating with iPod and tray icon, started Zimbra Desktop again - suddenly everything works!! the Zimbra Desktop toaster/tray-icon appeared! woohoo!
Worth a try for everybody else experiencing the same problem |
