python发送邮件和附件：Python操作Exchange邮箱发送邮件
安装包pip install Exchangelib代码
下面是使用outlook邮箱给QQ邮箱发送消息和附件的案例：

当然，除了发送邮件消息和附件之外，还可以抄送，密送给某人。只需要修改不同的参数即可
msg = Message(
folder=self.account.sent
account=self.account
subject=subject
body=HTMLBody(body)
to_recipients=to_recipients # 要发送的收件人邮箱地址列表
cc_recipients=cc_recipients # 要发送的抄送人邮箱地址列表
bcc_recipients=bcc_recipients # 要发送的密送人邮箱地址列表
)注意
注意，不同版本的Exchange有不同版本的version，可以在Exchange管理后台查看
注意：因为版本的不同很可能导致诸多问题，小编在客户那遇到了Exchange2007版本的，踩了不少坑，消息能发送，附件却发送不了，等等，大家使用中有遇到问题可关注小编，助你一臂之力
