需要用到 pywin32 库

安装

pip install pywin32

测试

import win32com.client as win32


outlook = win32.Dispatch('outlook.application')

报错如下，说明 没有安装outlook

发邮件

import win32com
import win32com.client

import re

outlook = win32com.client.Dispatch('outlook.application')

mail = outlook.CreateItem(0)
mail.GetInspector # 这里很关键，有了这代码，下面才能获取到outlook默认签名
mail.To = 'Microsoft Outlook <yumin_ma@163.com>' # 收件人
# mail.From = 'Microsoft Outlook <yumin_ma@163.com>'
mail.Subject = "这是标题"
print("========================")
# print(mail.HTMLBody) # 这里打印的就是签名，调用了mail.GetInspector之后，HTMLBody就会自动变为签名，需要添加正文的话，把正文加进去就好了
print("========================")
bodystart = re.search("<body.*?>", mail.HTMLBody) # 找到签名里面的body头，签名是html格式的
mail.HTMLBody = re.sub(bodystart.group(), bodystart.group()+"这里是正文", mail.HTMLBody) # 在签名里的body头后面插入正文
# mail.Body = "这里是邮件正文" #Body和HTMLBody只用一个
# mail.HTMLBody = "这里是html格式的正文" #Body和HTMLBody只用一个，使用HTMLBody可以设置邮件内容的格式
# mail.Attachments.Add("文件路加文件名")
mail.Send()

收邮件

import os
from win32com.client.gencache import EnsureDispatch as Dispatch  # 读取邮件模块


def read_outlook_mailbox():
    """连接Outlook邮箱，读取收件箱内的邮件内容"""
    # 使用MAPI协议连接Outlook
    account = Dispatch('Outlook.Application').GetNamespace('MAPI')

    # 获取收件箱所在位置
    inbox = account.GetDefaultFolder(6)  # 数字6代表收件箱
    # 获取收件箱下的所有邮件
    mails = inbox.Items
    mails_count=len(mails) # 邮件数量
    print("邮件数量：",mails_count)
    mails.Sort('[ReceivedTime]', True)  # 邮件按时间排序

    # 读取收件箱内前3封邮件的所有信息（下标从1开始）
    for index in range(1, mails_count):
        print('=====第[{}]封邮件...'.format(index))
        mail = mails.Item(index)
        print('接收时间：{}'.format(str(mail.ReceivedTime)[:-6]))
        print('发件人：{}'.format(mail.SenderName))
        print('收件人：{}'.format(mail.To))

        # print('会话ID：{}'.format(mail.ConversationID))
        # print('会话记录相对位置：{}'.format(mail.ConversationIndex))

        # 保存邮件中的附件，如果没有附件不会执行也不会产生异常
        # attachment = mail.Attachments
        # for each in attachment:
        #     save_attachment_path = os.getcwd()  # 保存附件到当前路径
        #     each.SaveAsFile(r'{}\{}'.format(save_attachment_path, each.FileName))
        #     print('附件（{}）保存完毕'.format(each.FileName))

        print("====================================")
