  1. I wrote code like this

    import win32com.client as win32
    import psutil
    import os
    import subprocess
    # Drafting and sending email notification to senders. You can add other senders' email in the list
    def send_notification():
        outlook = win32.Dispatch('Outlook.Application')
        mail = outlook.CreateItem(0x0)
        mail.To = '',
      #  mail.Subject = 'Sent through Python'
      #  mail.body = 'This email alert is auto generated. Please do not respond.'
      #  mail.send
    def open_outlook():
  ['C:\Program Files (x86)\Microsoft Office\root\Office16\OUTLOOK.EXE'])
            os.system('C:\Program Files (x86)\Microsoft Office\root\Office16\OUTLOOK.EXE');
            print("Outlook didn't open successfully")
    for item in psutil.pids():
        p = psutil.Process(item)
        if == "OUTLOOK.EXE":
            flag = 1
            flag = 0
    if (flag == 1):

    and the error:
    Traceback (most recent call last):
    File “C:/Users/satz/PycharmProjects/PYWork/Sample/”, line 33, in
    File “C:/Users/satz/PycharmProjects/PYWork/Sample/”, line 12, in send_notification
    mail.To = ‘’,

  2. Hi,

    What if i want to change “from” of email?

    Do you know something like
    mail. from=”” or mail.sender. None of them works for me.

    1. You have to remove the comma at the end of ‘mailTo’-line. This is leading to the error you get.

  3. Hi,

    I get this error message even though the path to the attachment is correct.

  5. Use this

    import win32com.client as win32
    outlook = win32.Dispatch('outlook.application')
    mail = outlook.CreateItem(0)
    mail.SentOnBehalfOfName = 'EMAIL'
    mail.To = 'EMAIL'
    mail.Subject = 'Message subject'
    mail.Body = 'Message body'
    mail.HTMLBody = 'HTML Message body' #this field is optional
    # To attach a file to the email (optional):
    attachment  = "Path to the attachment"
  6. Hey, what if i need to send the email to more than one accounts at the same time (not using a FOR loop to send it)

  7. Thank you so much, Edson

    It works for me!

    Use this

    import win32com.client as win32
    outlook = win32.Dispatch(‘outlook.application’)
    mail = outlook.CreateItem(0)
    mail.SentOnBehalfOfName = ‘EMAIL’
    mail.To = ‘EMAIL’
    mail.Subject = ‘Message subject’
    mail.Body = ‘Message body’
    mail.HTMLBody = ‘HTML Message body’ #this field is optional

    mail.Sensitivity = 1

    mail.Confidentiality = “Internal”

    mail.Label = 1

    I tried all the 3, nothing seem to work
