    Default Weird Calendar Sync Issues

    Hi all,

    Is Zimbra calendar sync really unstable for most people? I've recently installed Zimbra and I'm encountering a number of strange issues when syncing calendars with both Yahoo and Google:

    1) Most of the time Yahoo Calendar can't sync at all and gives me the following error message:

    com.zimbra.cs.mailbox.OfflineServiceException: must upgrade to all-new yahoo calendar service
    	at com.zimbra.cs.mailbox.OfflineServiceException.YCALDAV_NEED_UPGRADE(
    	at com.zimbra.cs.offline.OfflineCalDavDataImport.doCalDavFailures(
    	at com.zimbra.cs.offline.OfflineCalDavDataImport.importData(
    	at com.zimbra.cs.offline.OfflineImport.importData(
    	at com.zimbra.cs.offline.YMailImport.importData(
    	at com.zimbra.cs.datasource.DataSourceManager.importData(
    	at com.zimbra.cs.datasource.DataSourceManager.importData(
    	at com.zimbra.cs.mailbox.DataSourceMailbox.syncAllLocalDataSources(
    	at com.zimbra.cs.mailbox.DataSourceMailbox.sync(
    	at com.zimbra.cs.mailbox.DataSourceMailbox.syncOnTimer(
    	at com.zimbra.cs.mailbox.SyncMailbox$
    	at java.util.TimerThread.mainLoop(
    2) Yahoo Calendar can't login - "login auth details failed". If I don't get the first error, then I generally get this one.

    3) Occasionally Yahoo Calendar syncs without errors but misses out one of my calendars (shows in the list, but with zero appointments). I can create an appointment in Zimbra for this calendar and this appears in Yahoo, but no appointments sync to Zimbra from Yahoo

    4) Google calendars - only one of my five google calendars appear in Zimbra (no errors shown)

    Any ideas?

    OK, bit of an update to this error.

    Yahoo calendar now appears to be working - it just started syncing all calendars yesterday. Could this have been a problem with the Yahoo service itself?

    However, I still can see anything other than my default Google calendar - is this a problem that others have encountered? Is there a setting in Zimbra that I haven't checked - or do I need to do something in Google to enable Caldav access to my other Google calendars?
