    Default Upgrade from ZCS5 to 6 oddness in CalDAV iPhone sync

    Hi all,

    I just upgraded my ZCS to Release 6.0.2_GA_1912. After this I've noticed that I no longer get my calendar entries on my iPhone via CalDAV. Oddly enough the phone doesn't give any errors and seems to connect fine. I can create events on the phone and they show in Zimbra but not the other way around. I even noticed that when I changed the "color" of my calendar that it correctly changed on the phone as well so I know there is communication happening, but I must be missing something.


    Any help is much appreciated.


    Thanks!

    ZCS 6 seems to be quite broken so far as syncing is concerned. ZCS connector in Funambol and ical4ol both raise errors (depending how the configuration is made) because REPORT and PUT requests are not supported (error 400). SOAP doesn't seem to be supported for Contacts so that falls over too.

    Since I've been struggling for three weeks to fix 6 and thought it was my fault, the fellow workers are not too impressed, particularly when they realised they couldn't use Zimbra Desktop because that only supports one user per PC under Windows and we have multiple users per machine.

    Also there is an issue with Calendars disappearing until ZD is restarted - all in all my users aren't happy.

    So please, please someone tell me quickly how to downgrade 6 to 5 without losing everyone's data - it must be easy.

    I'm in the same boat as you two. My upgrade path was:

    From: 5.0.14_GA_2850.RHEL5_64_20090303145145 CentOS5_64
    To: 6.0.3_GA_1915.RHEL5_64_20091118095806 CentOS5_64

    iPhone 3.1.2 w/ CalDAV broke as soon as the upgrade was complete. Broke is a bad word though, because like you, some of the functionality remains:

    -- If I change the Calendar or Task "color" in Zimbra's web interface, the iPhone reflects the color changes in the Calendar root list.
    -- If I create an appointment on the iPhone, it is successfully added to Zimbra.
    -- If I delete THAT appointment from the iPhone, it is successfully deleted from Zimbra.
    -- Existing appointments within Zimbra simply do not appear.
    -- New appointments added to Zimbra web interface do not appear on the iPhone.

    There are no errors. I'm using a legitimate SSL certificate. I have completely power cycled the iPhone, and even removed/re-added the account. The Account URL I'm using is: https://mail.fqdn.com:443/principals...#37;40fqdn.com (swapping '%40' for '@' makes no difference).

    I tried syncing Zimbra 6.0.3 to iCal on my Macintosh using the same Account URL and it worked as intended. It would seem that iPhone 3.1.2's implementation of CalDAV no longer plays nice with ZCS 6.0.3's.

    What would be my next steps for troubleshooting this problem? I'm a fairly advanced systems admin, so getting technical is not an issue.

    Update! If you access your Zimbra account from iPhone 3.1.2 as a subscribed calendar (ICS), everything works fine. Read-only of course.

    Server: mail.fqdn.com/service/home/username@fqdn.com/calendar.ics

    Downgrade is a fuss but I achieved it by migrating twice - once to a temporary server running the downgraded version, reinstalling the downgraded version on the server then migrating back across. Of course, I had to redo all the setting up manually but, luckily, I don't have that many users yet.
    I'm not really a happy bunny because no-one has been able to suggest when the desktop beta will be available and we're not impressed with Mulberry (calendar display and update issues).
    However, the new version of 6 (6.0.3) seems to play nicely with ical4ol but I'm cautious about upgrading again if I will only have to remigrate when I discover something else is broken/semi-functional.

    hi

    i upgraded today to version 6.0.4, still wasn't able to receive the calendar via caldav.

    Then i found the problem.
    My Zimbra is running behind a apache reverse Proxy.
    and IPhone connects to /principals/users/username ... and got an error 404 (doesn't exist)

    no i added /principals to proxy to the Zimbra

    and now it work's as several weeks before.
    this was also needed to the productive zimbra 5 Server.

    did Apple change anything.

    best regards

    One of my users had the same issue, and he figured out a fix (for him):
    Under Settings/Mail, Contacts, Calendar/Calendars, I changed the Sync setting from "All Events" to "Events 1 month back" and the entries suddenly appeared.

    I've since changed the Sync setting back to "All Events" and "Events 6 months back" and they haven't disappeared. I'm going to leave it at "6 months back" for now.

    Best theory I have is that the initial transfer of "All Events" for indefinitely-reoccurring is too large and perhaps the server rejects it or it's too much data to transfer?
