iCal Sync problems for recurring meetings

[Hubert Fischer]

I've set up some recurring meetings in Team Calendars (e.g. weekly frequency). The Team Calendars is synchronized in iCal, where I see the recurring meetings. If I delete one event of a recurring meeting in Team Calendars, it won't be deleted in iCal: there I still see that the meeting takes place in the whole frequency. The deleted event of the frequency should NOT be displayed still in iCal. How can I fix this?
