using Outlook = Microsoft.Office.Interop.Outlook;

Outlook.Application outlookApp = new Outlook.Application();
Outlook.NameSpace outlookNamespace = outlookApp.GetNamespace("MAPI");

outlookNamespace.Logon(Missing.Value, Missing.Value, false, true);

Outlook.MAPIFolder inboxFolder = outlookNamespace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);

foreach (Outlook.MailItem mailItem in inboxFolder.Items)
{
    if (mailItem.Attachments.Count > 0)
    {
        foreach (Outlook.Attachment attachment in mailItem.Attachments)
        {
            // 保存附件到指定路径
            attachment.SaveAsFile("保存路径");
        }
    }
}

Marshal.ReleaseComObject(attachment);
Marshal.ReleaseComObject(mailItem);
Marshal.ReleaseComObject(inboxFolder);
Marshal.ReleaseComObject(outlookNamespace);
Marshal.ReleaseComObject(outlookApp);
