Outlook互操作服务在Windows任务计划程序中不起作用 [英] Outlook interop service is not working in windows task scheduler

问题描述

我开发了一个控制台应用程序来创建OUTLOOK会议请求。当我在Visual Studio中运行它时，它完美地工作。但是当我在任务计划程序中安排它时，它不起作用。它给了我波纹错误。

错误：操作不可用（HRESULT异常：0x800401E3（MK_E_UNAVAILABLE））

以下是我的代码。

  public  MeetingDVO sendOneTimeMeeting（MeetingDVO dvo）
 { 
 log.Info（  In side Send Onetime Meeting）; 
  object  outlookObject =  null ; 
 Outlook.Application oApp =  null ; 
 Outlook.AppointmentItem agendaMeeting =  null ; 
帐户acc =  null ; 
  string  status =  string  .Empty; 
 尝试 
 {
 outlookObject = Marshal.GetActiveObject（ < span class =code-string> Outlook.Application）; 
 
  if （outlookObject！=  null ）
 {
 log.Info（  Marshal Object Created）; 
 oApp =  new  Outlook.Application（）; 
} 
 其他 
 {
 oApp =  new  Microsoft.Office.Interop.Outlook.Application（）; 
} 
 
  if （ true ）
 { 
 log.Info（ 创建outlook对象）; 
  //   oApp = new Outlook.Application（）;  
  //   oApp = CreateOrAttachToOutlookApplication（）;  
 log.Info（ 对象创建）; 
 agendaMeeting =（Outlook.AppointmentItem）oApp.CreateItem（Microsoft.Office.Interop.Outlook.OlItemType.olAppointmentItem）; 
 log.Info（  agendaMeeting Object created）; 
 acc = SetAccount（oApp）; 
 log.Info（ 创建帐户）; 
  if （agendaMeeting！=  null ）
 {
 log。信息（ 在账户IF）; 
 Outlook.NameSpace nameSpace = oApp.GetNamespace（  MAPI）; 
 log.Info（ 命名空间）; 
 agendaMeeting.MeetingStatus = Microsoft.Office.Interop.Outlook.OlMeetingStatus.olMeeting; 
 agendaMeeting.Location = dvo.Location; 
 agendaMeeting.Subject = dvo.Subject; 
 agendaMeeting.Body = dvo.Body; 
 agendaMeeting.Start = dvo.TimeSlot; 
 agendaMeeting.Duration = dvo.Duration; 
  //   agendaMeeting.RequiredAttendees =[e-mail]; [e-mail];  
 agendaMeeting.RequiredAttendees =   [e-mail]; 
  //   agendaMeeting.RequiredAttendees =[e-mail];  
  //   agendaMeeting.ForceUpdateToAllAttendees = true;  
  //   agendaMeeting.ResponseRequested = true;  
（（Outlook._AppointmentItem）agendaMeeting）.SendUsingAccount = acc; 
（（Outlook._AppointmentItem）agendaMeeting）.Send（）; 
 dvo.EntryID = agendaMeeting.EntryID; 
 dvo.Remarks = MeetingSucess; 
 
} 
  else  
 dvo.Remarks = MeetingError +  ： +  会议对象为空 ; 
} 
} 
  catch （System.Exception ex）
 {
 log.Info（ex。 InnerException +   :::::: MESSAGE ---- + ex.Message）; 
 dvo.Remarks = MeetingError +  ： + ex.Message; 
} 
 最后 
 {
 oApp =  null  ; 
 agendaMeeting =  null ; 
 acc =  null ; 
} 
 
  return  dvo; 
} 
 

有什么建议吗？

解决方案

< blockquote>好吧，我可以告诉你错误信息，结合你的代码：

 outlookObject = Marshal.GetActiveObject（Outlook.Application）; 
 

表示在调用时Outlook似乎没有运行。

I have developed a console application to create OUTLOOK meeting requests. It is perfectly working fine when Im running it in Visual Studio. But when I schedule it in the Task Scheduler, it does not work. It gives me the bellow error.

Error : Operation unavailable (Exception from HRESULT: 0x800401E3 (MK_E_UNAVAILABLE))

below is my code.

public MeetingDVO sendOneTimeMeeting(MeetingDVO dvo)
   {
       log.Info("In side Send Onetime Meeting");
       object outlookObject = null;
       Outlook.Application oApp = null;
       Outlook.AppointmentItem agendaMeeting = null;
       Account acc = null;
       string status = string.Empty;
       try
       {
           outlookObject = Marshal.GetActiveObject("Outlook.Application");

           if (outlookObject != null)
           {
               log.Info("Marshal Object Created");
               oApp = new Outlook.Application();
           }
           else
           {
               oApp = new Microsoft.Office.Interop.Outlook.Application();
           }

           if (true)
           {
               log.Info("creating outlook Object");
               //oApp = new Outlook.Application();
               //oApp = CreateOrAttachToOutlookApplication();
               log.Info("Object created");
               agendaMeeting = (Outlook.AppointmentItem)oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olAppointmentItem);
               log.Info(" agendaMeeting Object created");
               acc = SetAccount(oApp);
               log.Info(" Account created");
               if (agendaMeeting != null)
               {
                   log.Info(" in side Account IF");
                   Outlook.NameSpace nameSpace = oApp.GetNamespace("MAPI");
                   log.Info(" Namespace");
                   agendaMeeting.MeetingStatus = Microsoft.Office.Interop.Outlook.OlMeetingStatus.olMeeting;
                   agendaMeeting.Location = dvo.Location;
                   agendaMeeting.Subject = dvo.Subject;
                   agendaMeeting.Body = dvo.Body;
                   agendaMeeting.Start = dvo.TimeSlot;
                   agendaMeeting.Duration = dvo.Duration;
                   //agendaMeeting.RequiredAttendees = "[e-mail];[e-mail]";
                   agendaMeeting.RequiredAttendees = "[e-mail]";
                   //agendaMeeting.RequiredAttendees = "[e-mail]";
                   //agendaMeeting.ForceUpdateToAllAttendees = true;
                   //agendaMeeting.ResponseRequested = true;
                   ((Outlook._AppointmentItem)agendaMeeting).SendUsingAccount = acc;
                   ((Outlook._AppointmentItem)agendaMeeting).Send();
                   dvo.EntryID = agendaMeeting.EntryID;
                   dvo.Remarks = MeetingSucess;

               }
               else
                   dvo.Remarks = MeetingError + " : " + "Meeting Object is Null";
           }
       }
       catch (System.Exception ex)
       {
           log.Info(ex.InnerException +":::::: MESSAGE----"+ex.Message);
           dvo.Remarks = MeetingError + " : " + ex.Message;
       }
       finally
       {
           oApp = null;
           agendaMeeting = null;
           acc = null;
       }

       return dvo;
   }

any suggestions?

解决方案

Well, I can tell you that the error message, combined with your code:

outlookObject = Marshal.GetActiveObject("Outlook.Application");

means that Outlook doesn't appear to be running at the time the call is made.
