EWS托管API：更新邮件时出现异常 [英] EWS Managed API: Exception when updating message

问题描述

我想使用以下代码将某些电子邮件的messageClass从IPM.Note更改为IPM.Note.MyForm：

EmailMessage message = EmailMessage.Bind（service，item.Id）;
message.ItemClass =" IPM.Note.MyForm" ;;
message.Update（ConflictResolutionMode.AlwaysOverwrite）;

当执行此代码我得到了解雇：

Microsoft.Exchange.WebServices.Data.ServiceXmlDeserializationException：预期的XML节点类型是Element，但实际类型是EndElement。在Microsoft。 Exchange.WebServices.Data.EwsXmlReader.Read（XmlNodeType nodeType）

但是，更改完成：我检查了消息的itemClass，我看到了新的消息。


有任何想法吗？

Hi,

I want to change the messageClass of certain e-mails from IPM.Note to IPM.Note.MyForm with the following code:

EmailMessage message = EmailMessage.Bind(service, item.Id);
message.ItemClass = "IPM.Note.MyForm";
message.Update(ConflictResolutionMode.AlwaysOverwrite);

When executing this code I get the excpetion:

Microsoft.Exchange.WebServices.Data.ServiceXmlDeserializationException: Expected
 XML node type was Element, but actual type is EndElement.

flictResolutionMode)
   at ExAccess.Access.run() in E:\projects\O2007\ExAccess\ExAccess\src\Access.cs
:line 109

Nevertheless, the change is done: When I check the itemClass of the message, I see the new one.


Any ideas ?

Thx
Mike

推荐答案

您是否可以在ExchangeService实例上启用EwsResponses跟踪并发布从Update调用返回的内容？我不相信你做错了什么 - 只是试图确定客户端API在阅读响应时遇到问题的原因。你需要做的就是添加以下几行...

Could you enable tracing for EwsResponses on the ExchangeService instance and post what is coming back from the Update call?  I don't believe you are doing anything wrong - just trying to determine why the client API is having trouble reading the response.

All you need to do to enable tracing is add the following lines...

service.TraceEnabled = true;
service.TraceFlags = EWS.TraceFlags.EwsResponse;

然后，响应将被追踪到控制台。

Then the response will be traced to the console.
