C# 设置电子邮件上的删除标志，IMAP收件箱中不会发生任何事情

我正在通过IMAP连接到webmail（Exchange 2003）

我用一个图书馆从做这件事

我看过一封邮件后，想把它删除。我的问题是它从未从我的邮箱中删除

所以我的问题是，Exchange中是否有允许“外部”用户删除邮件的设置

    foreach (MailMessage msg in msgs)
    {
        if (msg.HasAttachments)
        {

            foreach (Attachment attach in msg.Attachments)
            {
                // Save the attachment to the file.
                if (Path.GetExtension(attach.Filename).CompareTo(".csv") == 0)
                {
                    path = localFolder + "\\" + attach.Filename;
                    Console.WriteLine("Saved file: " + path);
                    attach.Save(@path, true);

                    paths.Add(path);

                    //deletes the message
                    imp.DeleteMessages(msg.IndexOnServer.ToString(), false);
                    Console.WriteLine("file nr:" + msg.IndexOnServer);
                }
                else
                {
                    Console.WriteLine("Found a different file: " + attach.Filename);
                }
            }

        }
    }

    DbHandler.Add(paths, backupMonths * -1);                

    return true;
}
catch (Exception e)
{
    Console.Out.WriteLine(e);
    return false;
}

这是MailBee库连接的日志

我认为这应该设置和删除消息。任何人都有什么问题吗？

根据您需要在调用

imp.Disconnect（）

之前调用

imp.Close（）

-否则消息不会被清除。

什么是imp对象，为什么要删除循环中用于附件的消息？我认为你应该删除内部foreach之外的消息…代码不是我的，我只是来修复它的。但是如果我接受了，我想我认为这是因为他/她只想删除带有附件的邮件。什么是imp对象，为什么要删除附件循环中的邮件？我认为你应该删除内部foreach之外的消息…代码不是我的，我只是来修复它的。但如果我接受了，我想我认为这是因为他/她只想删除带有附件的邮件。我不敢相信我错过了，但我想这是当你试图修复遗留代码=）时得到的结果。谢谢我不敢相信我错过了这一点，但我想这就是当您尝试修复遗留代码=）时得到的结果。谢谢
