C#和Exchange Web服务使用服务帐户错误

我正在尝试使用服务帐户访问“通知”电子邮件地址的收件箱。此服务帐户与我的帐户具有相同的访问权限，但没有自己的电子邮件地址，它只是一个服务帐户。当我使用我的帐户时，下面的测试代码起作用，但是当我使用服务帐户时，我得到以下错误：

当以没有邮箱的帐户进行请求时，您 必须为任何可分辨邮件指定邮箱主SMTP地址 文件夹ID

这段代码目前应该只显示收件箱中有多少封邮件主题为“测试”。我在这个网站上尝试了许多帖子的建议答案，但没有一个有效。谢谢你的帮助。代码如下：

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.Credentials = new WebCredentials("ServiceAccount", "Password");
service.AutodiscoverUrl("ScriptNotifications@domain.com", RedirectionUrlValidationCallback);
ItemView mView = new ItemView(10);
mView.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Descending);
string querystring = "subject:\"test\"";
Console.WriteLine("Total emails whos subject is 'test':");
FindItemsResults<Item> results = service.FindItems(new FolderId(WellKnownFolderName.Inbox, new Mailbox("ScriptNotifications@domain.com")), querystring, mView);
Console.WriteLine(results.Items.Count.ToString());

ImpersonatedUserId impersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, "smtp.mysmtpaddress.com");
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.Credentials = new NetworkCredential("ServiceAccount", "Password");
service.ImpersonatedUserId = impersonatedUserId;
service.AutodiscoverUrl("ScriptNotifications@domain.com", RedirectionUrlValidationCallback);
try
{
    AlternateIdBase response =
        service.ConvertId(new AlternateId(IdFormat.EwsId, "Placeholder", "ScriptNotifications@domain.com"), IdFormat.EwsId);


}
catch (ServiceResponseException)
{
    // Expected exception, see EWS documentation
    // Nonetheless, the credentials provided can authenticate successfully against this Exchange box

}
ItemView mView = new ItemView(10);
mView.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Descending);
string querystring = "subject:\"test\"";
Console.WriteLine("Total emails whos subject is 'test':");
FindItemsResults<Item> results = service.FindItems(new FolderId(WellKnownFolderName.Inbox, new Mailbox("ScriptNotifications@domain.com")), querystring, mView);
Console.WriteLine(results.Items.Count.ToString());

ExchangeService服务=新的ExchangeService（ExchangeVersion.Exchange2013\u SP1）；
service.Credentials=新的WebCredentials（“ServiceAccount”、“Password”）；
服务。自动发现URL（“ScriptNotifications@domain.com，重定向UrlValidationCallback）；
ItemView mView=新的ItemView（10）；
mView.OrderBy.Add（ItemSchema.DateTimeReceived，SortDirection.Descending）；
string querystring=“subject:\“test\”；
Console.WriteLine（“主题为“测试”的电子邮件总数：”）；
FindItemsResults=service.FindItems（新文件夹ID（WellKnownFolderName.Inbox，新邮箱（）ScriptNotifications@domain.com”），查询字符串，mView）；
WriteLine（results.Items.Count.ToString（））；

更新：

我想添加Noonand的代码，因为这给了我一个不同的错误。编辑以适应一个块而不是使用方法，下面是代码：

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.Credentials = new WebCredentials("ServiceAccount", "Password");
service.AutodiscoverUrl("ScriptNotifications@domain.com", RedirectionUrlValidationCallback);
ItemView mView = new ItemView(10);
mView.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Descending);
string querystring = "subject:\"test\"";
Console.WriteLine("Total emails whos subject is 'test':");
FindItemsResults<Item> results = service.FindItems(new FolderId(WellKnownFolderName.Inbox, new Mailbox("ScriptNotifications@domain.com")), querystring, mView);
Console.WriteLine(results.Items.Count.ToString());

ImpersonatedUserId impersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, "smtp.mysmtpaddress.com");
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.Credentials = new NetworkCredential("ServiceAccount", "Password");
service.ImpersonatedUserId = impersonatedUserId;
service.AutodiscoverUrl("ScriptNotifications@domain.com", RedirectionUrlValidationCallback);
try
{
    AlternateIdBase response =
        service.ConvertId(new AlternateId(IdFormat.EwsId, "Placeholder", "ScriptNotifications@domain.com"), IdFormat.EwsId);


}
catch (ServiceResponseException)
{
    // Expected exception, see EWS documentation
    // Nonetheless, the credentials provided can authenticate successfully against this Exchange box

}
ItemView mView = new ItemView(10);
mView.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Descending);
string querystring = "subject:\"test\"";
Console.WriteLine("Total emails whos subject is 'test':");
FindItemsResults<Item> results = service.FindItems(new FolderId(WellKnownFolderName.Inbox, new Mailbox("ScriptNotifications@domain.com")), querystring, mView);
Console.WriteLine(results.Items.Count.ToString());

ImpersonatedUserId ImpersonatedUserId=新的ImpersonatedUserId（ConnectingIdType.SmtpAddress，“smtp.mysmtpaddress.com”）；
ExchangeService服务=新的ExchangeService（ExchangeVersion.Exchange2013\u SP1）；
service.Credentials=新的网络凭据（“ServiceAccount”、“Password”）；
service.ImpersonatedUserId=ImpersonatedUserId；
服务。自动发现URL（“ScriptNotifications@domain.com，重定向UrlValidationCallback）；
尝试
{
交替碱基反应=
service.ConvertId（新的AlternateId（IdFormat.EwsId，“占位符”）ScriptNotifications@domain.com），IdFormat.EwsId）；
}
捕获（ServiceResponseException）
{
//预期异常，请参阅EWS文档
//尽管如此，提供的凭据仍可以针对此Exchange box成功进行身份验证
}
ItemView mView=新的ItemView（10）；
mView.OrderBy.Add（ItemSchema.DateTimeReceived，SortDirection.Descending）；
string querystring=“subject:\“test\”；
Console.WriteLine（“主题为“测试”的电子邮件总数：”）；
FindItemsResults=service.FindItems（新文件夹ID（WellKnownFolderName.Inbox，新邮箱（）ScriptNotifications@domain.com”），查询字符串，mView）；
WriteLine（results.Items.Count.ToString（））；

当我运行该代码时，在“FindItemResults”行出现以下错误：

SMTP地址没有与其关联的邮箱

更新2：

多亏了Noonand，我相信这个错误是Exchange Server 2013本身的一个缺陷。请参见以下链接：

我必须等到我公司的变更流程完成后才能进行更新，这可能需要很长时间，但我想把它发布出来，这样其他有同样问题的人可以看到这一点并得到帮助。

类似的东西应该适合你。这是输入到记事本（请原谅任何打字错误）而不是编译，因为它只是为了让你沿着正确的道路前进

public static ExchangeService ConnectToExchangeWithImpersonation(string userName, SecureString password, string impersonatedUserSmtpAddress, Uri serverUrl)
{
    ImpersonatedUserId impersonatedUserId =
      new ImpersonatedUserId(ConnectingIdType.SmtpAddress, impersonatedUserSmtpAddress);

    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2) // Change as appropriate
    {
        Credentials = new NetworkCredential(userName, password);
        ImpersonatedUserId = impersonatedUserId;
        Url = serverUrl;
    }

    // Connected, now authenticate
    try
    {
        AlternateIdBase response = 
            exchangeService.ConvertId(new AlternateId(IdFormat.EwsId, "Placeholder", userInformation.Username), IdFormat.EwsId);

    }
    catch (ServiceResponseException)
    {
        // Expected exception, see EWS documentation
        // Nonetheless, the credentials provided can authenticate successfully against this Exchange box
    }

    return service;
}

感谢您的尝试，但是，当我使用该代码时，会出现另一个错误。请参阅下面的代码。如果您遇到此错误，请参阅此处：我想是时候在中循环您的Exchange管理员了；-）啊哈！这听起来似乎正是问题所在。我将更新我的帖子，以确保人们看到链接。感谢您的尝试，但是，当我使用该代码时，我会遇到另一个错误。请参阅下面的代码。如果您遇到此错误，请参阅此处：我想是时候在中循环您的Exchange管理员了；-）啊哈！这听起来似乎正是问题所在。我会更新我的帖子，以确保人们看到链接。
