pywin32 and extended mapi: send email with attachments

StackOverflow https://stackoverflow.com/questions/15706089

Question

i am using the following code to send email with Simple MAPI Interface

import win32com.client
olMailItem = 0x0
obj = win32com.client.Dispatch("Outlook.Application")
newMail = obj.CreateItem(olMailItem)
newMail.Subject = "I AM SUBJECT!!"
newMail.Body = "I AM IN THE BODY\nSO AM I!!!"
newMail.To = "themail@mail.org"
#newMail.CC = "moreaddresses here"
#newMail.BCC = "aaa"
#attachment1 = "Path to attachment no. 1"
#attachment2 = "Path to attachment no. 2"
#newMail.Attachments.Add(attachment1)
#newMail.Attachments.Add(attachment2)
#newMail.display()
newMail.Send()

It seems to work even with Outlook 2007/2010, but it shows a warning for sending the mail.

Can I use Extended MAPI for sending emails without showing the warning, and sending attachments? If yes, where can I find an example?

Was it helpful?

Solution

No, you cannot use Extended with Python, you will need C++ or Delphi. Your options are given at http://www.outlookcode.com/article.aspx?id=52 - you can either install an up to date antivirus app or use an Extended MAPI wrapper, such as Redemption.

OTHER TIPS

Sorry for my english language..
I found a solution to add attachment on extended mapi using PyWin32 ...
This code isn'mine .. I added only the attachments part..
This sends message to outlook in html format or text format, including attachment embedded in html (the images) and other attachments..
The attachments can be every type file (.txt, .pdf, ecc ecc)
In this example code the html page and the attachments files must be in the same directory of this py code.

Outlook must be working to run this code successfully.. See MAPILogonEx .. https://msdn.microsoft.com/en-us/library/office/cc815545%28v=office.15%29.aspx
It use outlook for sending mails.. So if you are on a private net the Autenticathion part is just done running Outlook itself.. :)
