邮寄通过Outlook赎回邮寄Oulook发件箱

Question

这个问题正在发生，我们的客户之一，我一直无法在我身边复制使用相同版本的Outlook。我的客户和我正在使用安装了Outlook 2016的Office 365。当他通过Outlook Redemption（用于Outlook集成的第三方程序）在我们的程序中发送电子邮件时，邮件卡在他的发件箱中。

如果他双击消息（所以它在Outlook中弹出），他可以点击发送按钮，它会发送sucessfuly。如果他们使用旧版本的Outlook（2010），这不是问题。我当时将它们升级到最新版本的Outlook Redmeption（2016年5月7日发布），不过看起来他们几天前刚推出了新版本。我会很快尝试，但更改日志并未提及邮件卡在发件箱中。

我也注意到，在他的发件箱中的邮件有什么似乎是对他们的“草稿”的象征，而在我的发件箱中，他们对他们有“发送”符号。这似乎很重要，但我不确定我能做些什么。

此外，点击发送/接收所有文件夹不起作用。

我的代码如下。感谢您的帮助。

 public static bool SendMessage(Recipients recipients, string[] addressListReplyTo, string subject, string body, string[] attachments, bool requestReadReceipt, Log log, bool isHtmlBody = false) 
    { 
     RDOSession session = null; 
     RDOMail mail; 
     RDOFolder folder; 
     bool result = true; 

     session = GetSessionAndLogon(log); 
     if (session == null) 
      return false; 

     folder = session.GetDefaultFolder(rdoDefaultFolders.olFolderOutbox); 
     mail = folder.Items.Add(); 
     if (isHtmlBody) 
      mail.HTMLBody = body; 
     else 
      mail.Body = body; 
     mail.Subject = subject; 
     mail.ReadReceiptRequested = requestReadReceipt; 
     foreach (string attachment in attachments) 
     { 
      if (attachment != "") 
       mail.Attachments.Add(attachment); 
     } 
     foreach (string address in addressListReplyTo) 
     { 
      if (address != "") 
       mail.ReplyRecipients.Add(address); 
     } 
     foreach (string address in recipients.To) 
     { 
      if (address != "") 
       mail.Recipients.Add(address).Type = 1; 
     } 
     foreach (string address in recipients.Cc) 
     { 
      if (address != "") 
       mail.Recipients.Add(address).Type = 2; 
     } 
     foreach (string address in recipients.Bcc) 
     { 
      if (address != "") 
       mail.Recipients.Add(address).Type = 3; 
     } 

     foreach (RDORecipient recipient in mail.Recipients) 
     { 
      if (!OutlookMailEngine64.existsName(recipient.Name, session, log == null ? null : log)) 
       result = false; 
     } 
     if (result) 
     { 
      try 
      { 
       mail.Send(); 
       result = true; 
      } 
      catch (System.Runtime.InteropServices.COMException ex) 
      { 
       string message = "Error while sending email: " + ex.Message; 
       if (log != null) 
        log.Message(message); 
       if (OutlookMailEngine64.DiagnosticMode) 
        MessageBox.Show(message); 
       throw new EmailLibraryException(EmailLibraryException.ErrorType.InvalidRecipient, "One or more recipients are invalid (use OutlookMailEngine64.ValidateAddresses first)", ex); 
      } 
     } 
     if (session.LoggedOn) 
      session.Logoff(); 

     return result; 
    }

Dmitry通过电子邮件与我合作。对我来说，解决方案是将SafeMailItem对象的RDO换掉。这里是我的方法的更新版本，以便您可以看到更改：

private static bool SendSafeMessage(Recipients recipients, string[] addressListReplyTo, string subject, string body, string[] attachments, bool requestReadReceipt, Log log, bool isHtmlBody = false) 
    { 
     //This method was added because sometimes messages were getting stuck in the Outlook Outbox and this seems to solve that 
     bool result = true; 

     Microsoft.Office.Interop.Outlook.Application application = new Microsoft.Office.Interop.Outlook.Application(); 
     Microsoft.Office.Interop.Outlook.NameSpace namespaceMAPI = application.GetNamespace("MAPI"); 
     namespaceMAPI.Logon(); 
     RDOSession session = null; 
     session = GetSessionAndLogon(log); //TODO: I'm creating a 2nd session here which is wasteful 

     SafeMailItem safeMail = Redemption.RedemptionLoader.new_SafeMailItem(); 
     Microsoft.Office.Interop.Outlook.MailItem outlookMailItem = (Microsoft.Office.Interop.Outlook.MailItem)application.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem); 
     safeMail.Item = outlookMailItem; 

     if (isHtmlBody) 
      outlookMailItem.HTMLBody = body; 
     else 
      safeMail.Body = body; 
     outlookMailItem.Subject = subject; 
     outlookMailItem.ReadReceiptRequested = requestReadReceipt; 
     foreach (string attachment in attachments) 
     { 
      if (attachment != "") 
       safeMail.Attachments.Add(attachment); 
     } 
     foreach (string address in addressListReplyTo) 
     { 
      if (address != "") 
       safeMail.ReplyRecipients.Add(address); 
     } 
     foreach (string address in recipients.To) 
     { 
      if (address != "") 
       safeMail.Recipients.Add(address).Type = 1; 
     } 
     foreach (string address in recipients.Cc) 
     { 
      if (address != "") 
       safeMail.Recipients.Add(address).Type = 2; 
     } 
     foreach (string address in recipients.Bcc) 
     { 
      if (address != "") 
       safeMail.Recipients.Add(address).Type = 3; 
     } 

     foreach (Microsoft.Office.Interop.Outlook.Recipient recipient in outlookMailItem.Recipients) 
     { 
      if (!OutlookMailEngine64.existsName(recipient.Name, session, log == null ? null : log)) 
       result = false; 
     } 
     if (result) 
     { 
      try 
      { 
       safeMail.Send(); 
       result = true; 
      } 
      catch (System.Runtime.InteropServices.COMException ex) 
      { 
       string message = "Error while sending email: " + ex.Message; 
       if (log != null) 
        log.Message(message); 
       if (OutlookMailEngine64.DiagnosticMode) 
        MessageBox.Show(message); 
       throw new EmailLibraryException(EmailLibraryException.ErrorType.InvalidRecipient, "One or more recipients are invalid (use OutlookMailEngine64.ValidateAddresses first)", ex); 
      } 
     } 

     if (session.LoggedOn) 
      session.Logoff(); 

     namespaceMAPI.Logoff(); 

     return result; 
    }

请记住，邮件提交是异步的，它会n要被自动触发，除非您使用的是在线Exchange存储（其中存储和传输提供紧密耦合）。

您可以强制发送/通过在Outlook对象模型调用Namespace.SendAndReceive接收。
