如何将邮件项目从文件保存到outlook

import win32com.client

def save_email_to_outlook(subject, body, to, attachment_path, save_path):
    outlook = win32com.client.Dispatch("Outlook.Application")
    mail_item = outlook.CreateItem(0)
    mail_item.Subject = subject
    mail_item.Body = body
    mail_item.To = to
    mail_item.Attachments.Add(attachment_path)
    mail_item.SaveAs(save_path)

# 调用函数保存邮件到Outlook
save_email_to_outlook("邮件主题", "邮件正文", "收件人邮箱地址", "附件路径", "保存路径")
