Automating Outlook with pywin32

Platform note

pywin32pywin32 works on Windows.

It uses COM automation to control Outlook.

Example (send email)

outlook_send.py
# Windows-only
import win32com.client
 
 
def send_outlook(to: str, subject: str, body: str):
    outlook = win32com.client.Dispatch("Outlook.Application")
    mail = outlook.CreateItem(0)
    mail.To = to
    mail.Subject = subject
    mail.Body = body
    mail.Send()
 
 
# send_outlook("to@example.com", "Hi", "Hello from Outlook")
outlook_send.py
# Windows-only
import win32com.client
 
 
def send_outlook(to: str, subject: str, body: str):
    outlook = win32com.client.Dispatch("Outlook.Application")
    mail = outlook.CreateItem(0)
    mail.To = to
    mail.Subject = subject
    mail.Body = body
    mail.Send()
 
 
# send_outlook("to@example.com", "Hi", "Hello from Outlook")

Notes

  • COM automation can be blocked by security policies
  • prefer SMTP/APIs in server environments
