使用Outlook帳戶發送郵件

Question

我想發送EMail與C＃和Microsoft.Office.Interop.Outlook庫。

我被鎖定在我的Outlook帳號a@domain.com上，並獲得了交換服務器發送b@domain.com和c@domain.com的郵件的權利。

我沒有找到任何方式發送郵件B或C。

我得到了一切工作我的用戶帳戶，其中有郵件a@domain.com。

現在我找不到方法獲得b@domain.com的帳戶並以B的名義發送郵件。

我的問題：

如何訪問其他帳戶？

這是我的代碼有：

using Outlook = Microsoft.Office.Interop.Outlook; 
     public static Outlook.Account GetAccountForEmailAddress(Outlook.Application application, string smtpAddress) 
    { 

     // Loop over the Accounts collection of the current Outlook session. 
     Outlook.Accounts accounts = application.Session.Accounts; 
     if (_IsDebug) 
      Console.WriteLine($"Anzahl Accounts: {accounts.Count}"); 
     foreach (Outlook.Account account in accounts) 
     { 
      // When the e-mail address matches, return the account. 
      if (_IsDebug) 
       Console.WriteLine($"Account: {account.SmtpAddress}"); 
      if (String.Compare(account.SmtpAddress, smtpAddress, true) == 0) 
      { 
       return account; 
      } 
     } 
     throw new System.Exception(string.Format("No Account with SmtpAddress: {0} exists!", smtpAddress)); 
    } 
     static void SendEMail(string emailadress) 
    { 
     try 
     { 
      var outlookApplication = new Outlook.Application(); 
      var outlookMailItem = (Outlook.MailItem)outlookApplication.CreateItem(Outlook.OlItemType.olMailItem); 

      outlookMailItem.SendUsingAccount = GetAccountForEmailAddress(outlookApplication, ConfigurationManager.AppSettings[SENDER]); 


      if (_IsDebug) 
       Console.WriteLine($"Absender: {outlookMailItem?.SendUsingAccount?.SmtpAddress}"); 

      outlookMailItem.HTMLBody = ConfigurationManager.AppSettings[BODY]; 

      if (_IsDebug) 
       Console.WriteLine($"Body: {outlookMailItem?.HTMLBody}"); 

      var file = GetPDFFile(); 
      if (_IsDebug) 
       Console.WriteLine($"File: {file?.Name}"); 

      if (file == null) 
      { 
       Console.WriteLine("Keine Datei gefunden!"); 
       return; 
      } 

      string attachementDisplayName = file.Name; 

      int attachementPosition = outlookMailItem.HTMLBody.Length + 1; 
      int attachementType = (int)Outlook.OlAttachmentType.olByValue; 

      if (_IsDebug) 
       Console.WriteLine($"Dateianhang: {file.FullName}"); 

      Outlook.Attachment outlookAttachement = outlookMailItem.Attachments.Add(file.FullName, attachementType, attachementPosition, attachementDisplayName); 

      outlookMailItem.Subject = ConfigurationManager.AppSettings[SUBJECT]; 

      Outlook.Recipients outlookRecipients = outlookMailItem.Recipients; 
      Outlook.Recipient outlookRecipient = outlookRecipients.Add(emailadress); 

      outlookRecipient.Resolve(); 

      outlookMailItem.Send(); 

      outlookRecipient = null; 
      outlookRecipients = null; 
      outlookMailItem = null; 
      outlookApplication = null; 

      if (_IsDebug) 
       Console.ReadLine(); 
     } 
     catch (Exception) 
     { 
      throw; 
     } 
    }

您有權授予發送郵箱所有者發送當你想從發送的電子郵件郵箱的權限。代表發送權限將可用，但會說「A代表B」作爲發件人。
