在电子邮件上设置删除标志，IMAP 收件箱中没有任何反应

Question

我通过 IMAP 连接到网络邮件 (Exchange 2003)。

我使用 mailbee 中的库来执行此操作。

我读完一封邮件后希望将其删除。我的问题是它从未从我的邮箱中删除。

所以我的问题是，Exchange 中是否有某些设置必须允许“外部”用户删除邮件？

    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 库的连接日志，

我认为这应该设置和删除消息。有人对出了什么问题有任何意见吗？

根据有关DeleteMessages的Mailbee示例代码的文档 在调用 imp 之前，您需要先调用 imp.Close()。 Disconnect() - 否则消息将不会被清除。
