This repository contains a Python 3.6 module for reading Microsoft Outlook .msg files and converting them to .eml format, which is the standard MIME format for email messages.
Install the dependencies with:
pip3.6 install -r requirements.txt
Then either convert a single file by piping:
python3.6 outlookmsgfile.py < message.msg > message.eml
Or convert a set of files:
python3.6 outlookmsgfile.py *.msg
When passing filenames as command-line arguments, a new file with .eml
appended to the filename is written out with the message in MIME format.
To use it in your application
import outlookmsgfile
eml = outlookmsgfile.load('my_email_sample.msg')
The load() function returns an EmailMessage instance.
