如何设置 ExchangeService 的 ReponseMessage 的优先级

Question

我正在使用 Microsoft.Exchange.WebServices.Data.ExchangeService 查找特定电子邮件并回复全部。我知道使用 System.Net.Mail 的 MailMessage，我可以设置 Priority 属性。我没有看到使用 ExchangeService?

的等价物

var exchangeService = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
exchangeService.Credentials = new WebCredentials("usr", "pw", "myDomain.com");
exchangeService.TraceEnabled = false;
exchangeService.AutodiscoverUrl($"{usr}@myDomain.com", AutodiscoverRedirectionUrlValidationCallback);

它找到一封电子邮件：

var filter = new SearchFilterCollection(LogicalOperator.And, new IsEqualTo(EmailMessageSchema.IsRead, false));
var results = exchangeService.FindItems(WellKnownFolderName.Inbox, filter, new ItemView(50));

var interesting = results.Items.FirstOrDefault(e => e.Subject == "interesting");

它创建一个回复所有电子邮件：

var response = interesting.CreateReply(true);
response.Body = "I'm important!";
response.Priority = MailPriority.High; // No such property?

response.SendAndSaveCopy();

Answer 1

做之前 var response = interesting.CreateReply(true);

像这样设置有趣变量的重要性 interesting.Importance = Importance.Low; 注意：如果 var interesting 不是 EmailMessage 则先施放。它可能是 Item

类型

当您致电 CreateReply() 时，重要性将转移到回复中。

我是这样测试的

var interesting = results.Items.FirstOrDefault();
var orignal = (EmailMessage)interesting; 
orignal.Importance = Importance.Low; orignal.CreateReply(true); 
orignal.Subject = "Low priority"; 
orignal.ToRecipients.Add("myemail@domain.com"); 
orignal.SendAndSaveCopy();

原始邮件优先级高，回复优先级低
