如何使用 Python 和 Microsoft Exchange 发送带有附件的电子邮件？

有人可以帮我从我的交换帐户发送电子邮件并添加附件吗？ SMTP 不起作用，我立即遇到超时问题。 0365 没有将副本保存到我的已发送文件夹中。我唯一知道的另一个是exchangelib

from exchangelib import Account, Credentials, Message, Mailbox, FileAttachment
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email.mime.text import MIMEText
from email.utils import formatdate
from email import encoders

email = 'XXXXXXXX'
password = 'XXXXXXXX'

a = Account(email, credentials=Credentials(email, password), autodiscover=True)



dir_path = ('C:/Users/Istcrmt/Documents/Python/PythonforAnaconda3.5/')
excel_name = 'test.xlsx'

#attach an excel file:


for i in email_list.itertuples():
# if you want a copy in the 'Sent' folder
    m = Message(
        account=a 
        ,folder=a.sent
        ,subject=(i.AGENCY_NAME + ' I made an email script.')
        ,body='All bodies are beautiful' 
        ,to_recipients=[Mailbox(email_address=i.NEW_MAIL)])

#attach files
    m.attachments.append(part) 
   # m.attach(cover_letter)

    m.send_and_save()

这是发送带有附件的电子邮件的方式exchangelib:

from exchangelib import ServiceAccount, Configuration, Account, DELEGATE
from exchangelib import Message, Mailbox, FileAttachment

from config import cfg  # load your credentials


def send_email(account, subject, body, recipients, attachments=None):
    """
    Send an email.

    Parameters
    ----------
    account : Account object
    subject : str
    body : str
    recipients : list of str
        Each str is and email adress
    attachments : list of tuples or None
        (filename, binary contents)

    Examples
    --------
    >>> send_email(account, 'Subject line', 'Hello!', ['[email protected] /cdn-cgi/l/email-protection'])
    """
    to_recipients = []
    for recipient in recipients:
        to_recipients.append(Mailbox(email_address=recipient))
    # Create message
    m = Message(account=account,
                folder=account.sent,
                subject=subject,
                body=body,
                to_recipients=to_recipients)

    # attach files
    for attachment_name, attachment_content in attachments or []:
        file = FileAttachment(name=attachment_name, content=attachment_content)
        m.attach(file)
    m.send_and_save()


credentials = ServiceAccount(username=cfg['user'],
                             password=cfg['password'])

config = Configuration(server=cfg['server'], credentials=credentials)
account = Account(primary_smtp_address=cfg['smtp_address'], config=config,
                  autodiscover=False, access_type=DELEGATE)

# Read attachment
attachments = []
with open('filestorage/numbers-test-document.pdf', 'rb') as f:
    content = f.read()
attachments.append(('whatever.pdf', content))

# Send email
send_email(account, 'Test 14:35', 'works', ['[email protected] /cdn-cgi/l/email-protection'],
           attachments=attachments)
