处理阅读电子邮件的应用程序。 除了webdav还有办法将所有电子邮件从Exchange Server 2003发送到我的本地计算机。 webdav的问题在于它不会成为Undelivered电子邮件的主体。
CredentialCache creds = new CredentialCache();
creds.Add(new Uri(a), "NTLM",
new NetworkCredential("xxxxx", "xxxxxx", "xxxxx.com"));
List<Mail> unreadMail = new List<Mail>();
string reqStr =
@"<?xml version=""1.0""?>
<g:searchrequest xmlns:g=""DAV:"">
<g:sql>
SELECT
""urn:schemas:mailheader:from"",
""urn:schemas:mailheader:to"",
""urn:schemas:httpmail:textdescription""
FROM
""http://xxxx.com/exchange/xxxx/Inbox/""
WHERE
""urn:schemas:httpmail:subject"" = 'Undeliverable: xxxx'
</g:sql>
</g:searchrequest>";
byte[] reqBytes = Encoding.UTF8.GetBytes(reqStr);
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(a);
request.Credentials = creds;
request.Method = "SEARCH";
request.ContentLength = reqBytes.Length;
request.ContentType = "text/xml";
request.Timeout = 300000;
using (Stream requestStream = request.GetRequestStream())
{
try
{
requestStream.Write(reqBytes, 0, reqBytes.Length);
}
catch
{
}
finally
{
requestStream.Close();
}
}
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (Stream responseStream = response.GetResponseStream())
{
try
{
XmlDocument document = new XmlDocument();
document.Load(responseStream);
XmlNamespaceManager nsmgr = new XmlNamespaceManager(document.NameTable);
nsmgr.AddNamespace("a", "DAV:");
nsmgr.AddNamespace("b", "urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/");
nsmgr.AddNamespace("c", "xml:");
nsmgr.AddNamespace("d", "urn:schemas:mailheader:");
nsmgr.AddNamespace("e", "urn:schemas:httpmail:");
XmlNodeList responseNodes = document.GetElementsByTagName("a:response");
foreach (XmlNode responseNode in responseNodes)
{
XmlNode uriNode = responseNode.SelectSingleNode("child::a:href", nsmgr);
XmlNode propstatNode = responseNode.SelectSingleNode("descendant::a:propstat[a:status='HTTP/1.1 200 OK']", nsmgr);
if (propstatNode != null)
{
// read properties of this response, and load into a data object
XmlNode fromNode = propstatNode.SelectSingleNode("descendant::d:from", nsmgr);
XmlNode descNode = propstatNode.SelectSingleNode("descendant::e:textdescription", nsmgr);
XmlNode toNode = propstatNode.SelectSingleNode("descendant::d:to", nsmgr);
// make new data object
Mail mail = new Mail();
if (uriNode != null)
mail.Uri = uriNode.InnerText;
if (fromNode != null)
mail.From = fromNode.InnerText;
if (descNode != null)
mail.Body = descNode.InnerText;
if (toNode != null)
mail.To = toNode.InnerText;
unreadMail.Add(mail);
}
}
var ac = unreadMail;
}
catch (Exception e)
{
string msg = e.Message;
}
finally
{
responseStream.Close();
}
}
在输出xml中,我得到未发送电子邮件的空文本描述:
<a:status>HTTP/1.1 404 Resource Not Found</a:status><a:prop><e:textdescription /></a:prop></a:propstat></a:response>

您可以尝试以与OWA相同的方式向服务器发送HTTP请求(当然在其中指定邮件ID) - 然后您将获得可以解析的HTML。
另外 - 检查原始邮件是否在“未送达”电子邮件的附件数组中。

我看到几个与Exchange服务器通信的选项 - WebDAV很难使用,并且在以后的版本(2010)中得不到很好的支持,MS提供了EWS,但这些不适用于旧版本。
从我的POV中,您可以使用以下任何组件(商业!):
另一点:
当处理Undeliverable
邮件时,我体验到身体有时作为附件提供 - 在WebDAV中,这需要通过X-MS-ENUMATT
动词来访问(但是请注意:特定的“附件”,如winmail .dat由Outlook在显示屏上自动“解码”。
