Currious behavior of GetUserAvailability

Hi,

i am  trying to connect to a exchange 2010 server to get all available appointments for a period of time. For this i am using the GetUserAvailabity Method from the Exchange Web Services. For example i have a time window from (2011-10-31 00:00:00 to 2011-11-07 00:00:00) with this information the code goes like this: TimeWindow pTimeWindow = new TimeWindow(rangeFrom, rangeTo); availabilityResults = m_sService.GetUserAvailability(m_sAttendees, pTimeWindow, AvailabilityData.FreeBusyAndSuggestions, m_sAvailabilityOptions); I only got the available appointment for the first day (2011-10-31 00:00 to 2011-11-01 00:00) and no other appointments so far. If i read everyday of this week as one day, i get all appointments, but i try to get the comparison of reading a time window day by day and reading the whole time window and sorting it then. So cann you tell me what my fault is, or did i misunderstood anything,

Thanks for your help,

Best regards from Germany,

Hartwig Pudzich
