Question

我正在使用Microsoft Exchange Web服务（托管API）开发ASP.NET Web应用程序。我的目标是提供会议室地址列表作为输入，并使用GetUserAvailability从Exchange服务器获取忙/闲信息，以便在给定的会议时间内向用户建议开放的会议室。我有有效的代码，但是当我尝试将DetailedSuggestionsWindow限制为会议持续时间时，出现错误：

为FreeBusyViewOptions.TimeWindow指定的持续时间无效。

我知道我可以扩大时间范围-但随后我得到的数据又超出了我的需要。有人可以在特定时间（通常为30分钟-2小时）内找到建议的会议室吗？

您可以参考以下链接：

// Create a collection of attendees. 
List<AttendeeInfo> attendees = new List<AttendeeInfo>(); 

attendees.Add(new AttendeeInfo() 
{ 
    SmtpAddress = "mack@contoso.com", 
    AttendeeType = MeetingAttendeeType.Organizer 
}); 

attendees.Add(new AttendeeInfo() 
{ 
    SmtpAddress = "sadie@contoso.com", 
    AttendeeType = MeetingAttendeeType.Required 
}); 

// Specify options to request free/busy information and suggested meeting times.
AvailabilityOptions availabilityOptions = new AvailabilityOptions(); 
availabilityOptions.GoodSuggestionThreshold = 49; 
availabilityOptions.MaximumNonWorkHoursSuggestionsPerDay = 0;
availabilityOptions.MaximumSuggestionsPerDay = 2;
// Note that 60 minutes is the default value for MeetingDuration, but setting it explicitly for demonstration purposes.
availabilityOptions.MeetingDuration = 60; 
availabilityOptions.MinimumSuggestionQuality = SuggestionQuality.Good; 
availabilityOptions.DetailedSuggestionsWindow = new TimeWindow(DateTime.Now.AddDays(1), DateTime.Now.AddDays(2));
availabilityOptions.RequestedFreeBusyView = FreeBusyViewType.FreeBusy;

// Return free/busy information and a set of suggested meeting times. 
// This method results in a GetUserAvailabilityRequest call to EWS.
GetUserAvailabilityResults results = service.GetUserAvailability(attendees, 
                                                                 availabilityOptions.DetailedSuggestionsWindow, 
                                                                 AvailabilityData.FreeBusyAndSuggestions, 
                                                                 availabilityOptions);

Answer 2

根据https://docs.microsoft.com/en-us/dotnet/api/microsoft.exchange.webservices.data.exchangeservice.getuseravailability

方法仅支持至少24小时长的时间段然后开始和结束于凌晨12:00限制结果方法到较短的时间段，您必须在客户。

因此，您无法通过所需的时间窗口。尝试删除与会者并查询仅房间的可用性，以获取更完整的结果集。
