Python3.5 执行发邮件Exchangelib(=)

fyl

Python发邮件的代码如下：

只需要填写好加粗字体，即可正常使用。

from exchangelib import DELEGATE, Account, Credentials, Message, Mailbox, HTMLBody

def Email(to, subject, body):
    creds = Credentials(
        username='xxxxxx',
        password='xxxxxx'
    )
    account = Account(
        primary_smtp_address='xxx@xxx.com',
        credentials=creds,
        autodiscover=True,
        access_type=DELEGATE
    )
    m = Message(
        account=account,
        subject=subject,
        body=HTMLBody(body),
        to_recipients = [Mailbox(email_address=to)]
    )
    m.send()

Email("xxx@xxx.com", "abc", "def")

但是如果Python环境安装有瑕疵，则报错如下：

$python3 ab.py
Traceback (most recent call last):
  File "ab.py", line 22, in <module>
    Email("xxx@xxx.com", "abc", "def")
  File "ab.py", line 12, in Email
    access_type=DELEGATE
  File "/usr/local/lib/python3.5/site-packages/exchangelib/account.py", line 66, in __init__
    credentials=credentials)
  File "/usr/local/lib/python3.5/site-packages/exchangelib/autodiscover.py", line 214, in discover
    email=email)
  File "/usr/local/lib/python3.5/site-packages/exchangelib/autodiscover.py", line 236, in _try_autodiscover
    return _try_autodiscover(e.server, credentials, email)
  File "/usr/local/lib/python3.5/site-packages/exchangelib/autodiscover.py", line 262, in _try_autodiscover
    raise_from(AutoDiscoverFailed('All steps in the autodiscover protocol failed'), None)
  File "/usr/local/lib/python3.5/site-packages/future/utils/__init__.py", line 398, in raise_from
    exec(execstr, myglobals, mylocals)
  File "<string>", line 1, in <module>
exchangelib.errors.AutoDiscoverFailed: All steps in the autodiscover protocol failed

至今仍无解。

好在我有台机器安装Python3.5.2正常，执行上述完全没有问题。

今天终于搞定！！！ 2017-12-11

exchange的版本不对，

我本机版本：
pip3 search exchangelib
exchangelib (1.10.6)  - Client for Microsoft Exchange Web Services (EWS)
  INSTALLED: 1.9.4
  LATEST:    1.10.6

服务器版本为：
$pip3 search exchangelib
exchangelib (1.10.6)  - Client for Microsoft Exchange Web Services (EWS)
  INSTALLED: 1.10.4
  LATEST:    1.10.6

要做的就是把服务器上的版本降低到1.9.4，就
