exchangewebservices - MS Exchange Web 服务 : How to get items with 'Flag' set?

Question

有人知道如何使用 Microsoft Exchange Web 服务获取收件箱内标记的所有项目吗？

显然，它们既不在“任务”文件夹内(即使它们出现在 Outlook 中)，也没有将 IsReminderSet 设置为 true。

以下尝试仅返回约会或仅返回真实任务，但不返回标记的消息:

var msgsView = new ItemView(100);
var msgsFilter = new SearchFilter.IsEqualTo(ItemSchema.IsReminderSet, true);
var flagged = exSvc.FindItems(WellKnownFolderName.Inbox, msgsFilter, msgsView);

或

var taskView = new ItemView(100);
var tasks = exSvc.FindItems(WellKnownFolderName.Tasks, taskView);

都不起作用。

我知道这个问题已经很老了，但我刚刚找到了列表示例代码，看起来它可能可以解决问题(我自己还没有测试过)来源:http://independentsoft.de/exchangewebservices/tutorial/findmessageswithflag.html

    IsEqualTo restriction1 = new IsEqualTo(MessagePropertyPath.FlagStatus, "1"); //FlagStatus.Complete
    IsEqualTo restriction2 = new IsEqualTo(MessagePropertyPath.FlagStatus, "2"); //FlagStatus.Marked

    Or restriction3 = new Or(restriction1, restriction2);

    FindItemResponse response = service.FindItem(StandardFolder.Inbox
                 , MessagePropertyPath.AllPropertyPaths, restriction3);

for (int i = 0; i < response.Items.Count; i++)
{
    if (response.Items[i] is Message)
    {
         Message message = (Message)response.Items[i];

         Console.WriteLine("Subject = " + message.Subject);
         Console.WriteLine("FlagStatus = " + message.FlagStatus);
         Console.WriteLine("FlagIcon = " + message.FlagIcon);
         Console.WriteLine("FlagCompleteTime = " + message.FlagCompleteTime);
         Console.WriteLine("FlagRequest = " + message.FlagRequest);
         Console.WriteLine("-----------------------------------------------");
    }
}
