Python操作Mircrosoft Exchange邮箱

公司的邮箱只有50M,时常需要清理，于是写了个清理工具：

import os
import time
import logging
import configparser
from exchangelib import DELEGATE, Account, Credentials, Configuration, NTLM,  Build, Version
from exchangelib.protocol import BaseProtocol, NoVerifyHTTPAdapter
import warnings

class ngmail(object):
    def __init__(self):
        warnings.filterwarnings('ignore')
        config = configparser.ConfigParser()
        isread = config.read('ngmail.ini')
        self.server='mail.xxx.cn'
        if len(isread)==0:
            username = input("请输入邮箱用户名: ")
            pwd = input("请输入邮箱密码: ")
            config.add_section('userinfo')
            config.set('userinfo', 'username', username)
            config.set('userinfo', 'password', pwd)
            f = open('ngmail.ini', "w")
            config.write(f)  
            f.close()
            self.username=username
            self.password=pwd
        else:
            self.username = config['userinfo']['username']
            self.password = config['userinfo']['password']

    def deleteMail(self):
        isdelete =input("确定删除所有邮件？(y/n),输入y并回车将删除所有邮件  ")
        if isdelete=='y' or isdelete=='Y':
            BaseProtocol.HTTP_ADAPTER_CLS = NoVerifyHTTPAdapter
            version = Version(build=Build(14, 3, 123, 0))
            credentials = Credentials(username=self.username, password=self.password)
            config = Configuration(
                server=self.server, credentials=credentials, version=version, auth_type=NTLM
            )
            # NTLM
            account = Account(primary_smtp_address=self.username, config=config, access_type=DELEGATE)
            try:
                status_report = account.inbox.all().delete()
                print('成功清空邮箱')
                time.sleep(1)
            except Exception as e:
                if e.value.find("Wrong username")>-1:
                    print('用户名或密码不正确')
                    os.remove('ngmail.ini')
                    self.__init__()
                    self.deleteMail()
                else:
                    raise e

if __name__=='__main__':
    try:
        tt= ngmail()
        tt.deleteMail()

    except Exception as e:
        logging.exception(e)
        os.system('pause')    

使用exchangelib的时候，可以指定exchange的版本，从而减少没必要的探测，详细使用规则可以查看官方文档：https://pypi.org/project/exchangelib/
