Exchange 2007 Webservice GetItem错误 [英] Exchange 2007 webservice GetItem error
问题描述
您好，
我有一个月以来运行的Exchange Server 2007并且从来没有遇到过问题，但是我来到这个mornnig我得到了这个错误。我有一个用户订阅，可以收到新邮件的通知。之后，我有一个系统可以在一定的时间间隔内收到消息。
因为我们正在测试我有开发一个小应用程序，每分钟发送一个邮件来测试系统负载，这是一周以来运行，从来没有遇到过问题。我没有更新，没有任何变化，但现在我无法使用网络服务......
这很奇怪，有人得到了这个错误或者有什么可能导致这个错误的线索。我还把代码放在电子邮件底部的项目中。
非常感谢。

这是代码：
有趣。看起来返回的正文类型枚举值中的某些内容会导致xml序列化程序在您的客户端上死亡。有趣的是，嗅探网络流量以查看返回的消息是什么样的，尤其是Body元素上的BodyType属性值。
另一个选择是只请求IdOnly的基本形状，因为您已经获得了消息的MimeContent。或者，您可以尝试在GetItem请求的响应形状中明确请求HTML或Text BodyType。
Hello,
I have Exchange Server 2007 running since a month and never got a problem, but wHen I came in this mornnig I get this error. I have a user subscription that receive notification for new mails. After that I have a system that get the message on a certain interval.
because we are in test I have developp a little app that send a mail every minute to test the system load, this is running since a week and never got a problem. I've done no update, nothing has change, but now I can't use the webservice...
This is strange, did someone got this error or has a clue on what could cause that. I've also put the code to get the item at the bottom of the email.
thanks a lot.

Here's the code :
Interesting. Looks like something in the returned body type enumeration value is causing the xml serializer to die on your client. It would be interesting to sniff the network traffic to see what the returned message looks like, especially the BodyType attribute value on the Body element.
Another option is to just request a base shape of IdOnly since you are already getting the MimeContent of the message. Or, you could try explicitly requesting the HTML or Text BodyType in the response shape of your GetItem request.
