求助：使用Python3.6向Outlook联系人发送每周邮件通知

针对你的问题，提供两个可行方案，均适配Python3.6环境：

方案一：通过smtplib对接企业Outlook SMTP服务 #

企业Outlook基于Exchange服务器，只需配置正确的SMTP参数即可使用smtplib发送邮件，无需局限于Gmail。

关键配置与代码示例 #

• 确认企业邮箱的SMTP地址（通常为outlook.office365.com，内部部署的Exchange可能有专属地址）、端口（推荐587，启用TLS加密）
• 部分企业要求使用域账号密码或应用专用密码，需联系IT确认权限

import smtplib
from email.mime.text import MIMEText
from email.header import Header

# 邮箱配置
sender = "your-work-email@company.com"
password = "your-domain-password-or-app-password"
smtp_server = "outlook.office365.com"
smtp_port = 587

# 构建邮件内容
msg = MIMEText("每周通知正文内容", "plain", "utf-8")
msg["From"] = Header("通知推送", "utf-8")
msg["To"] = Header("收件人", "utf-8")
msg["Subject"] = Header("每周工作通知", "utf-8")

# 发送邮件
try:
    with smtplib.SMTP(smtp_server, smtp_port) as server:
        server.starttls()  # 启用TLS加密，必须步骤
        server.login(sender, password)
        server.sendmail(sender, ["recipient@company.com"], msg.as_string())
    print("邮件发送成功")
except Exception as e:
    print(f"发送失败: {str(e)}")

方案二：使用exchangelib库对接Exchange服务 #

exchangelib是专门为Exchange设计的Python库，完美兼容Python3.6，无需依赖win32com，支持自动发现Exchange服务器。

步骤与代码示例 #

1. 安装兼容版本的exchangelib：

pip install exchangelib==4.7.0

（注：4.7.0是最后一批支持Python3.6的版本，更高版本需Python3.7+）

2. 代码实现：

from exchangelib import Credentials, Account, Message, Mailbox

# 账号认证
creds = Credentials(
    username="your-work-email@company.com",
    password="your-domain-password"
)
# 自动发现Exchange服务器，企业环境通常可用
account = Account(
    primary_smtp_address="your-work-email@company.com",
    credentials=creds,
    autodiscover=True,
    access_type="delegate"
)

# 构建并发送邮件
email = Message(
    account=account,
    subject="每周工作通知",
    body="这是每周通知的正文内容",
    to_recipients=[Mailbox(email_address="recipient@company.com")]
)
email.send()
print("邮件发送成功")

补充说明 #

• 若autodiscover=True失败，可手动指定Exchange服务器地址，例如：

account = Account(
    primary_smtp_address="your-work-email@company.com",
    credentials=creds,
    server="https://outlook.office365.com/EWS/Exchange.asmx",
    access_type="delegate"
)
