Frequent outlook calendar sync failures
One of our users manages multiple "medium sized" shared calendars with Outlook and is experiencing about two or three sync issues a day.
First, some general information:
- System: Windows XP Professional 32bit SP4 German on a Dell Latitude laptop
- Outlook: 2007 SP2.
- Zimbra Connector for Outlook Version 220.127.116.1124 as downloaded from the ZCS admin interface.
- Server: ZCS Version 7.1.1_GA_3213, ubuntu server running as a virtual machine on a local VMWare ESX 4 installation.
The problem seems to occur when the user does a drag and drop of an appointment in outlook (e.g. to change the start and end time). Outlook will "accept" the change and show the appointment at its new place without showing any immediate error messages.
However, after a "send and receive", a new mail is sent to the user, informing him that there was a sync issue:
In Zimbra webmail, the appointment still has the old information.
Local Failures were detected. No action is required.
This e-mail was generated for technical support purposes.

Until now, all the appointments that produced these problems were recurring appointments.
I've logged the problem using ZCOLogCtl.exe, with http logging and verbose logging enabled. The excerpt can be found attached to this thread (I've replaced the user name with "Fristname Lastname"). The subject of the problematic appointment is "De Etalage Eijsden".
