How to send SMTP email for office365 with python u

问题:

I am trying to send an email from my office365 corporate account using python. I am new to python. This code previously worked when using my hotmail account, however now that I have a need to send confidential information, I must use my corporate email.

I have tried a couple things.

• Verified that my username and password is correct.
• Used both python2 and python3. Both give the same error: 535 5.7.3 Authentication unsuccessful
• I previously was using mailserver.starttls() when I got the above error, then after some research, I tried to pass a
  certificate.mailserver.starttls(certfile='office365.cer')

I am unclear on the certificate part, but my steps include, looking online to find out how to export a certificate. Using chrome browser, microsoftonline.com has a chain certificate. I can export the root and the level just below the root but not the last level. I dont know how to pass both of these files, so I have simply passed the root certificate. At this point I get the error: ssl.SSLError: [SSL] PEM lib (_ssl.c:3309)

i got stuck at this point. Any help is appreciated. Code used below

import smtplib

mailserver = smtplib.SMTP('smtp.office365.com',587)
mailserver.ehlo()
mailserver.starttls(certfile='office365.cer')
mailserver.ehlo()
mailserver.login('[e-mail]', 'password')
mailserver.sendmail('[e-mail]','[e-mail]','python email')
mailserver.quit()

Well, you are almost there. The following code will do the trick:

import smtplib

mailserver = smtplib.SMTP('smtp.office365.com',587)
mailserver.ehlo()
mailserver.starttls()
mailserver.login('[e-mail]', 'password')
mailserver.sendmail('[e-mail]','[e-mail]','python email')
mailserver.quit()

I found a library that it's working for me:

https://github.com/Narcolapser/python-o365

https://pypi.python.org/pypi/O365

Install it using PIP and then:

from O365 import Message
o365_auth = ('[e-mail]','YourPassword')
m = Message(auth=o365_auth)
m.setRecipients('[e-mail]')
m.setSubject('I made an email script.')
m.setBody('Talk to the computer, cause the human does not want to hear it any more.')
m.sendMessage()

The code has slightly changed. The above code won't work. Please use the below code. Reference

from O365 import Account

credentials = ('client_id', 'client_secret')

account = Account(credentials)
m = account.new_message()
m.to.add('[e-mail]')
m.subject = 'Testing!'
m.body = "George Best quote: I've stopped drinking, but only while I'm asleep."
m.send()
