We are creating an application where we are extracting GroupWise calendar events and migrating them to Google Apps domain. GroupWise creates each occurance of recurring event individually. e.g. If there is a daily recurring event of 5 occurances. In this case GroupWise creates 5 individual events each with recurrance rule. If we delete one of the events in this series (Termed as Cancel Exception), the recurrance rule gets changed but it doesn't specify about the deleted event. Google needs the deleted event's date while creating the recurring event.

We are able to create the recurrance rule as per Google's specifications except the cancel exception. Any help is appreciated.

Thanks in advance!
