c# - 尝试使用 EWS MANAGED API 访问 Exchange 2010 帐户时“找不到自动发现服务”

Question

我正在为指定的电子邮件地址使用自动发现服务 Url。

ExchangeService Service = new ExchangeService(ExchangeVersion.Exchange2010);
Service.Credentials = new WebCredentials("username@domainname.com", "Password");
Service.AutodiscoverUrl("username@domainname.com");
Folder inbox = Folder.Bind(Service, WellKnownFolderName.Inbox);
Console.WriteLine("The folder name is" + inbox.DisplayName.ToString());

如果我这样做，我会出错:

The Autodiscover service couldn't be located

我必须怎么做才能避免这个错误？

Answer 1

你的 Service.Credentials 错了，像这样使用它:

Service.Credentials = new WebCredentials(username, password, domainname);

使用域凭据，而不是电子邮件地址。

还要仔细检查以下内容:

1. 您在 new ExchangeService() 中指定的版本与服务器的相匹配
2. 传递给Service.AutodiscoverUrl();的参数正确(需要抓取数据的邮箱地址)

以下对我有用(在新的控制台应用程序中):

// Tweaked to match server version
ExchangeService Service = new ExchangeService(ExchangeVersion.Exchange2007_SP1); 

// Dummy but realistic credentials provided below
Service.Credentials = new WebCredentials("john", "12345678", "MYDOMAIN");
Service.AutodiscoverUrl("john.smith@mydomain.it");
Folder inbox = Folder.Bind(Service, WellKnownFolderName.Inbox);
Console.WriteLine("The folder name is " + inbox.DisplayName.ToString());

//Console output follows (IT localized environment, 'Posta in arrivo' = 'Inbox')
> The folder name is Posta in arrivo
