我正在使用Exchange Server发送带有SmtpClient（正在成功发送）的MailMessages，但希望我发送的电子邮件转到我发送给他们的电子邮件地址的已发送文件夹（未发生）。
using (var mailMessage = new MailMessage("fromaddress@blah.com", "toaddress@blah.com", "subject", "body"))
{
var smtpClient = new SmtpClient("SmtpHost")
{
EnableSsl = false,
DeliveryMethod = SmtpDeliveryMethod.Network
};
// Apply credentials
smtpClient.Credentials = new NetworkCredential("smtpUsername", "smtpPassword");
// Send
smtpClient.Send(mailMessage);
}
我是否缺少可以确保我发送的所有“fromaddress@blah.com”电子邮件到达其已发送文件夹的配置？

我已经这样做了，所以为了完整性，这里是如何正确地做到这一点。使用托管交换Web服务（http://msdn.microsoft.com/en-us/library/dd633709%28EXCHG.80%29.aspx）：
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
// In case you have a dodgy SSL certificate:
System.Net.ServicePointManager.ServerCertificateValidationCallback =
delegate(Object obj, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
{
return true;
};
service.Credentials = new WebCredentials("username", "password", "MYDOMAIN");
service.Url = new Uri("https://exchangebox/EWS/Exchange.asmx");
EmailMessage em = new EmailMessage(service);
em.Subject = "example email";
em.Body = new MessageBody("hello world");
em.Sender = new Microsoft.Exchange.WebServices.Data.EmailAddress("john.smith@example.com");
em.ToRecipients.Add(new Microsoft.Exchange.WebServices.Data.EmailAddress("bob.smith@example.com"));
// Send the email and put it into the SentItems:
em.SendAndSaveCopy(WellKnownFolderName.SentItems);

我猜你的要求主要是为了让用户能够看到已发送的电子邮件。发送的项目文件夹将是允许这种情况发生的一种方法。在过去，我通过添加BCC Address来解决此问题，该using (var mailMessage = new MailMessage(
"fromaddress@blah.com",
"toaddress@blah.com",
"",
"fromaddress@blah.com",
"subject",
"body"))
{
var smtpClient = new SmtpClient("SmtpHost")
{
EnableSsl = false,
DeliveryMethod = SmtpDeliveryMethod.Network
};
// Apply credentials
smtpClient.Credentials = new NetworkCredential("smtpUsername", "smtpPassword");
// Send
smtpClient.Send(mailMessage);
}
会直接将电子邮件发送到分发列表，用户或共享邮箱，以允许用户查看已发送的内容。
尝试使用某种Outlook规则将项目移动到标记为读取的已发送项目文件夹...

我一直在寻找这个问题的答案，但不依赖于Exchange Server，而是使用IMAP服务器。我不知道这是否超出了问题的范围，但我发现它正在搜索＆＃34;将已发送的MailMessage发送到已发送的文件夹＆＃34;这首先是我的问题。
Haven在我建立自己的解决方案的任何地方找到了直接答案：
我实现了将save方法作为smtpClient的扩展，因此，我们将使用.Send()而不是.SendAndSaveMessageToIMAP()。
public static class SmtpClientExtensions
{
static System.IO.StreamWriter sw = null;
static System.Net.Sockets.TcpClient tcpc = null;
static System.Net.Security.SslStream ssl = null;

static byte[] buffer;
static System.Text.StringBuilder sb = new System.Text.StringBuilder();
static byte[] dummy;
/// <summary>

private static void SendCommandAndReceiveResponse(string command)
{
try
{
if (command != "")
{
if (tcpc.Connected)
{
dummy = System.Text.Encoding.ASCII.GetBytes(command);
ssl.Write(dummy, 0, dummy.Length);
}
else
{
throw new System.ApplicationException("TCP CONNECTION DISCONNECTED");
}
}
ssl.Flush();
buffer = new byte[2048];
bytes = ssl.Read(buffer, 0, 2048);
sb.Append(System.Text.Encoding.ASCII.GetString(buffer));
sw.WriteLine(sb.ToString());
sb = new System.Text.StringBuilder();
}
catch (System.Exception ex)

if (System.IO.File.Exists(path))
System.IO.File.Delete(path);

var sr = new System.IO.StreamReader(m);
var myStr = sr.ReadToEnd();
SendCommandAndReceiveResponse(string.Format("$ APPEND {1} (\\Seen) {{{2}}}{0}", System.Environment.NewLine, sentFolderName, myStr.Length));

}
catch (System.Exception ex)
{
System.Diagnostics.Debug.WriteLine("error: " + ex.Message);
}
finally
{
if (sw != null)
{
sw.Close();
sw.Dispose();
}

所以Robert Reid的榜样将成为
using (var mailMessage = new MailMessage("fromaddress@blah.com", "toaddress@blah.com", "subject", "body"))
{
//Add an attachment just for the sake of it
Attachment doc = new Attachment(@"filePath");
doc.ContentId = "doc";
mailMessage.Attachments.Add(doc);
var smtpClient = new SmtpClient("SmtpHost")
{
EnableSsl = false,
DeliveryMethod = SmtpDeliveryMethod.Network
};
// Apply credentials
smtpClient.Credentials = new NetworkCredential("smtpUsername", "smtpPassword");
// Send
smtpClient.SendAndSaveMessageToIMAP(mailMessage, "imap.mail.com", 993, "imapUsername", "imapPassword", "SENT");
}

如果要在“已发送邮件”文件夹中包含已发送邮件，则需要从Outlook发送邮件。此文件夹是Outlook（以及许多其他邮件客户端）概念，而不是SMTP概念。
您可以使用Outlook Automation API要求Outlook创建电子邮件并发送。
