如何使用 C# 以编程方式读取 Outlook 电子邮件，一天工作，另一天停止工作？

Question

我的目标是使用我的 C# 脚本自动读取 Outlook 电子邮件。上周，它正常工作，没有任何问题。自本周初以来，我收到以下错误： “由于以下错误，检索具有 CLSID 的组件的 COM 类工厂失败：80080005 服务器执行失败” 我的代码如下：

using System;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using olook = Microsoft.Office.Interop.Outlook;

namespace ReadingEmails
{
    internal class Program
    {
        public static (string[], olook.MailItem[]) ReadMail()
        {
            try
            {
                List<string> bodyList = new List<string>();
                List<olook.MailItem> emailList = new List<olook.MailItem>();

                olook.Application outlookApp = new olook.Application();

                olook.Folder inbox = outlookApp.Session.GetDefaultFolder(olook.OlDefaultFolders.olFolderInbox) as olook.Folder;
                olook.Folders childFolders = inbox.Folders;
                foreach (olook.Folder folder in childFolders)
                {
                    //Reason behind this that if we have an outlook rule to automate moving emails into specific
                    //folder it will be less emails than the inbox for the script to navigate through
                    if (folder.Name == "testFolder")
                    {
                        //Retrieving mail items from the folder
                        olook.Items mailItems = folder.Items;
                        foreach (object item in mailItems)
                        {
                            if (item is olook.MailItem)
                            {
                                olook.MailItem mailItem = (olook.MailItem)item;
                                //Will only be looking at emails with subject line: Manual Incoming2
                                //Only looking at unread emails, otherwise we will have infinite loop
                                //of emails being sent
                                if (mailItem != null && mailItem.Subject != null && mailItem.UnRead)
                                {
                                    if (mailItem.Subject.Contains("Incoming"))
                                    {
                                        //will not look at any emails that are replies or fowards. otherwise
                                        //we will have infinite loop of emails being sent
                                        try
                                        {
                                            if (!mailItem.Subject.Contains("RE:") || !mailItem.Subject.Contains("FW:"))
                                            {
                                                Console.WriteLine(DateTime.Now + " : Found Email");
                                                bodyList.Add(mailItem.Body);
                                                emailList.Add(mailItem);
                                                //make email read so that we can avoid infinite loops of emails
                                                //being sent
                                                mailItem.UnRead = false;
                                            }
                                        }
                                        catch (System.Exception ex) { Console.WriteLine(ex.Message); }
                                    }
                                }
                            }
                        }
                    }
                }
                Marshal.ReleaseComObject(outlookApp);
                return (bodyList.ToArray(), emailList.ToArray());
            }
            catch (System.Exception ex) { Console.WriteLine(ex.Message); }
            return (null, null);
        }
        static void Main(string[] args)
        {
            (string[] bodyArray, olook.MailItem[] emails) = ReadMail();
            Console.ReadLine();
        }
    }
}

我的 Microsoft.Office.Interop.Outlook.dll 被选中。我正在使用文件版本 14.0。我的虚拟机上的 Outlook 应用程序是最新的。我没有窗口更新。我已经重新启动了我的虚拟机。我不明白为什么它有效，现在它不起作用。

错误 80080005 服务器执行失败（即

CO_E_SERVER_EXEC_FAILURE

）很可能意味着您的应用程序和 Outlook 在不同的安全上下文中运行，并且 COM 系统拒绝封送调用。

确保两个应用程序都以提升的权限运行（以管理员身份运行），或者都不运行。
