I develope module and use soap interface to zimbra. I can create mail account without a problem. but when I try to make an appointment I found Internal Server Error reply back. It may be wrong with the parameter for create appointment. So I try "GetApptSummariesRequest" which is a complex parameter unavailable. It still reply back with "Internal Server Error". My Soap structure like this.
<GetApptSummariesRequest s="1072224000000" e="1198368000000"/>
Is someone help me please?
