Reading e-mail without Outlook app open
提问by
Thats what I am using to read e-mail using C#:
这就是我使用 C# 阅读电子邮件的方式：
outLookApp.NewMailEx += new ApplicationEvents_11_NewMailExEventHandler(outLookApp_NewMailEx);
Outlook.NameSpace olNameSpace = outLookApp.GetNamespace("mapi");
olNameSpace.Logon("xxxx", "xxxxx", false, true);
Outlook.MAPIFolder oInbox = olNameSpace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
Outlook.Items oItems = oInbox.Items;
MessageBox.Show("Total : " + oItems.Count); //Total Itemin inbox
oItems = oItems.Restrict("[Unread] = true");
MessageBox.Show("Total Unread : " + oItems.Count); //Unread Items
Outlook.MailItem oMsg;
Outlook.Attachment mailAttachement;
for (int i = 0; i < oItems.Count; i++)
{
oMsg = (Outlook.MailItem)oItems.GetFirst();
MessageBox.Show(i.ToString());
MessageBox.Show(oMsg.SenderName);
MessageBox.Show(oMsg.Subject);
MessageBox.Show(oMsg.ReceivedTime.ToString());
MessageBox.Show(oMsg.Body);
The problem that I am facing is this application only works if the Outlook is open on the machine. If Outlook is closed it throws an exception:
我面临的问题是此应用程序仅在机器上打开 Outlook 时才有效。如果 Outlook 已关闭，则会引发异常：
The server is not available. Contact your administrator if this condition persists.
服务器不可用。如果这种情况持续存在，请联系您的管理员。
Is there anyway I can read e-mail with Outlook open?
无论如何，我可以在打开 Outlook 的情况下阅读电子邮件吗？

Are you sure you want to use Outlook as a proxy?
您确定要将 Outlook 用作代理吗？
peopleseemsto deal low level with such a task in C# (surprising there isn't any built-in component in the framework...)
人们似乎在 C# 中处理这样的任务的低级别（令人惊讶的是框架中没有任何内置组件......）
Concerning Mat's response, Redemption is indeed a fine product (used it to parse mails upon arrival in outlook), but I doubt it can work without outlook running.
关于 Mat 的回应，Redemption 确实是一个很好的产品（用它来解析到达 Outlook 的邮件），但我怀疑它可以在没有 Outlook 运行的情况下工作。

I would personally not use Outlook as a proxy. If you're trying to ultimately monitor an Exchange store, then I'd use WebDav. Your Exchange server must support it - but if it does, it's a simple XML API. Well, the API bit is simple, but the XML is quite convoluted. But once you've encapsulated this in a bit of code, it's a doddle to use.
我个人不会使用 Outlook 作为代理。如果您尝试最终监控 Exchange 商店，那么我会使用 WebDav。您的 Exchange 服务器必须支持它 - 但如果支持，它就是一个简单的 XML API。嗯，API 位很简单，但 XML 相当复杂。但是一旦你把它封装在一些代码中，使用起来就很容易了。

Use a MAPI client to retrieve the emails and a MIME decoder to read them. Both exists in the lumisoft framework:
使用 MAPI 客户端检索电子邮件并使用 MIME 解码器读取它们。两者都存在于 lumisoft 框架中：

This is kind of an old question, but I am going to answer it since I struggled with the same issue for a long time and the previous answers on this page did not really help me.
这是一个古老的问题，但我将回答它，因为我在同一个问题上挣扎了很长时间，而本页上的先前答案并没有真正帮助我。
I had to write a program and use outlook to send an email on different machines with different UAC-levels and this is what I came up with after a long time.
我不得不编写一个程序并使用 Outlook 在具有不同 UAC 级别的不同机器上发送电子邮件，这是我经过很长时间才想到的。
using Outlook = Microsoft.Office.Interop.Outlook;
// Create the Outlook application.
Outlook.Application oApp = null;
// Check whether there is an Outlook process running.
int outlookRunning = Process.GetProcessesByName("OUTLOOK").Length;
if (outlookRunning > 0)
{
// If so, use the GetActiveObject method to obtain the process and cast it to an Application object.
try
{
oApp = Marshal.GetActiveObject("Outlook.Application") as Outlook.Application;
}
catch (Exception)
{
oApp = Activator.CreateInstance(Type.GetTypeFromProgID("Outlook.Application")) as Outlook.Application;
}
finally
{
// At this point we must kill Outlook (since outlook was started by user on a higher prio level than this current application)
// kill Outlook (otherwise it will only work if UAC is disabled)
// this is really a kind of last resort
Process[] workers = Process.GetProcessesByName("OUTLOOk");
foreach (Process worker in workers)
{
worker.Kill();
worker.WaitForExit();
worker.Dispose();
}
}
}
else
{
// If not, create a new instance of Outlook and log on to the default profile.
oApp = new Outlook.Application();
Outlook.NameSpace nameSpace = oApp.GetNamespace("MAPI");
try
{
// use default profile and DO NOT pop up a window
// on some pc bill gates fails to login without the popup, then we must pop up and lets use choose profile and allow access
nameSpace.Logon("", "", false, Missing.Value);
}
catch (Exception)
{
// use default profile and DO pop up a window
nameSpace.Logon("", "", true, true);
}
nameSpace = null;
}
// Done, now you can do what ever you want with the oApp, like creating a message and send it
// Create a new mail item.
Outlook.MailItem oMsg = (Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);
