c# - 从 exchange 服务器读取外出办公室供其他用户使用 C#

Question

我正在尝试从我的 C# 程序中读取组织中其他用户的外出状态和消息。我们在本地运行 Exchange 2013。

此应用作为 Active Directory 帐户运行(具有自己的交换邮箱)，我无法使用模拟。

我花了一些时间尝试解决类似问题，例如:

• Retrieve out of office Status using EWS 2.0这个使用模拟
• Read out of office from exchange server for other users我没有使用 Outlook 对象模型
• How to get Out of Office for another mailbox再次禁止冒充我
• http://gsexdev.blogspot.com/2011/11/using-mailtips-in-ews-to-get-oof-out-of.html我没有引用 ExchangeServiceBinding，即使我使用的是 Microsoft.Exchange.WebServices.Data;
• http://blogs.msdn.com/b/devmsg/archive/2014/06/03/ews-how-to-retrieve-the-oof-out-of-facility-settings-message-using-ews-for-an-exchange-user.aspx这一个作为参数 urlname 并且我不确定该 url 来自哪里。这个似乎是最有前途的，有什么想法是从哪里来的吗？

我想得到类似的东西:

public void checkOOF(string userEmail){
bool isOOF = checkstuff(userEmail);
string message;
if(isOOF)
   message = getOOFMessage(userEmail);
}

请帮我理解一下，谢谢。

这就是我最终使用的并且有效。

public static string getOOM(string emailToCheck) //needs to be full email of user.
{
            string EWSurl = String.Format("https://{0}/EWS/Exchange.asmx", ExchangePath);
            WebRequest webRequest = WebRequest.Create(EWSurl);
            HttpWebRequest httpwebRequest = (HttpWebRequest)webRequest;
            httpwebRequest.Method = "POST";
            httpwebRequest.ContentType = "text/xml; charset=utf-8";
            httpwebRequest.ProtocolVersion = HttpVersion.Version11;
            httpwebRequest.Credentials = new NetworkCredential("user", "password", "domain");//service Account
            httpwebRequest.Timeout = 60000;
            Stream requestStream = httpwebRequest.GetRequestStream();
            StreamWriter streamWriter = new StreamWriter(requestStream, Encoding.ASCII);

            StringBuilder getMailTipsSoapRequest = new StringBuilder("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"");
            getMailTipsSoapRequest.Append(" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" ");
            getMailTipsSoapRequest.Append("xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" ");
            getMailTipsSoapRequest.Append("xmlns:t=\"http://schemas.microsoft.com/exchange/services/2006/types\"><soap:Header>");
            getMailTipsSoapRequest.Append(" <t:RequestServerVersion Version=\"Exchange2010\"/></soap:Header><soap:Body>");
            getMailTipsSoapRequest.Append("<GetMailTips xmlns=\"http://schemas.microsoft.com/exchange/services/2006/messages\">");
            getMailTipsSoapRequest.Append("<SendingAs>");
            getMailTipsSoapRequest.Append("<t:EmailAddress>accessingemail@domain.com</t:EmailAddress>");
            getMailTipsSoapRequest.Append("<t:RoutingType>SMTP</t:RoutingType></SendingAs>");
            getMailTipsSoapRequest.Append("<Recipients><t:Mailbox>");
            getMailTipsSoapRequest.Append("<t:EmailAddress>" + emailToCheck + "</t:EmailAddress>");
            getMailTipsSoapRequest.Append("<t:RoutingType>SMTP</t:RoutingType></t:Mailbox></Recipients>");
            getMailTipsSoapRequest.Append(" <MailTipsRequested>OutOfOfficeMessage</MailTipsRequested></GetMailTips>");
            getMailTipsSoapRequest.Append("</soap:Body></soap:Envelope>");

            streamWriter.Write(getMailTipsSoapRequest.ToString());
            streamWriter.Close();
            HttpWebResponse webResponse = (HttpWebResponse)httpwebRequest.GetResponse();

            StreamReader streamreader = new StreamReader(webResponse.GetResponseStream());
            string response = streamreader.ReadToEnd();
            if (response.Contains("<t:Message/>"))
                return null;
            int messageIndex = response.IndexOf("<t:Message>");
            response = response.Substring(messageIndex, response.IndexOf("</t:Message>") - messageIndex);
            return response;
}
