Calendar sync stops for one user

[Devereux]

We are using BES with Zimbra and have 6 blackberries running.
Mail and calendar sync is fine from and to blackberry , but not for one user.
For this client the mail sync is ok, but the calendar sync has stopped suddenly. All users are running outlook 2003 on their desktops, and the sync between their desktops and the zimbra server is ok for all users.

Any hints where to look for the missing calendar sync for the user with the problem?

Thanks,

Michael

First thing to check is whether calendar sync problem occurs between BES and zimbra server or between BES and BB device. In order to determine this, stop BB controller, open up 'BlackBerryServer' mail profile with Outlook and check if calendar events are displayed for user in question. In case if calendar events are successfully syncing to 'BlackBerryServer' profile then the problem occurs somewhere between BES and BB device in which case you may want to try to delete/undelete calendar related service books, check 'wireless synchronization' settings for calendar on BB device or any other possible recommendations that can be found on blackberry forums. Please also note that these solutions are not related to zimbra connector and are common for all supported messaging servers.

Nevertheless, if problem occurs between zimbra server and BES then first thing i would check is 'Local Failures' folder for user in question using Outlook, if there is nothing in there you may need to enable zcb logging (type zcoloctl.exe in command prompt) and see if you can find anything obvious for user in question in zcb or MAGT logs. Please also do not hesitate to file support case(support@zimbra.com) with logs attached. Please try to re-provision and re-activate problematic device as option of last resort.

Thanks for your answers. It seems to be a problem between zimbra server and BES, the calendar from the zimbra server was not synced with the outlook on the BES. In the meantime, I did a reboot of the server with the BES.
After that, the calender for the user with the problem begins to sync , but only for calendar entries created after the reboot...
