如何使用兑换连接到 Office 365 邮箱

Question

我想使用兑换连接到 Office 365 并从收件箱和其他文件夹下载所有电子邮件，我的开发机器是

Windows 10 X64
Visual Studio 2015 专业版
我的开发机器上没有安装 Outlook
已安装 Microsoft Exchange Server MAPI 客户端和协作数据对象 1.2.1 来自此 link
使用此命令在我的 form1.cs 文件中注册 redemption.dll regsvr32.exe <fullpath>\redemption.dll
在我的项目中引用 Interop.Redemption.dll

这是我尝试连接Office365邮箱的代码

  string codeBase = System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase;
            UriBuilder uri = new UriBuilder(codeBase);
            string path = Uri.UnescapeDataString(uri.Path);
            path = Path.GetDirectoryName(path);

            RedemptionLoader.DllLocation32Bit = string.Concat(path, @"\Redemption.dll");
            RedemptionLoader.DllLocation64Bit = string.Concat(path, @"\Redemption64.dll");

            RDOSession session = RedemptionLoader.new_RDOSession();

            session.LogonHostedExchangeMailbox("smtp.office365.com", "abc@domain.com","xxxx");// getting error at this line               

            if (session.LoggedOn)
            {
                RDOFolder contactsFolder;    
                contactsFolder = session.GetDefaultFolder(rdoDefaultFolders.olFolderContacts);
                var i = contactsFolder.Folders.Count;

                foreach (var item in contactsFolder.Folders)
                {
                    var obj = (RDOFolder2)item;
                    var name = obj.AddressBookName;    
                }
            }

这是我收到的错误

成功完成此任务的任何建议。

要连接到 Office 365 邮箱（或 Exchange 2013 或 2016 上的任何邮箱），您需要 Outlook 版本的 MAPI（Outlook 2010 SP2、Outlook 2013 SP1 或 Outlook 2016）- MAPI 的独立版本无法连接，因为 Exchange 将拒绝连接。

另请注意，LogonHostedExchangeMailbox 中的第一个参数是用户的 SMTP 地址，而不是服务器名称。
