使用手动设置的凭证时，EWS自动发现停止工作 [英] When using manually set credentials, EWS auto discover stops working
问题描述
我遇到了一个非常奇怪的问题，我确信这只是我忽略的愚蠢行为.使用EWS托管API，我尝试连接到邮箱以读取联系人.最初，我使用默认凭据，在这种情况下，自动发现有效.问题在于，稍后我们要在服务器上运行它并模拟用户，因此我通过手动指定凭据来对其进行了更改.即使使用我自己的凭据，这也打破了.
I am running into a very strange issue and I am convinced it is just something stupid that I am overlooking. Using the EWS managed API, I try to connect to a mailbox to read the contacts. Originally, I used the default credentials, in which case the auto discovery worked. The problem is that later on we want to run this on a server and impersonate a user, so I changed it by manually specifying the credentials. This then broke, even when using my own credentials.
作为一个例子，它起作用:
As an example, this worked:
service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.AutodiscoverUrl("user@example.com", redirect => true);
这没有:
service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.UseDefaultCredentials = false;
service.Credentials = new NetworkCredential("user", "pass", "EXAMPLE_DOMAIN");
service.AutodiscoverUrl("user@example.com", redirect => true);
给定的网络凭据应与默认凭据完全相同，但是在启用跟踪时，在第二种情况下，我会收到响应"401未经授权"，因此它的作用就好像是相同的一样.
The given network credentials should be exactly the same as the default credentials, but when enabling the tracing, I get the response "401 Unauthorized" in the second case, so it is not acting as if it is the same.
我想念什么?
推荐答案
好吧，看来您需要使用WebCredential("user", "pass", "EXAMPLE_DOMAIN").我不确定为什么WebCredentials可以工作，但是NetworkCredentials不能.
Ok, it seems that you need to use WebCredential("user", "pass", "EXAMPLE_DOMAIN"). I am not exactly sure why WebCredentials work but NetworkCredentials does not.
