extract-msg is a Python library designed to parse and extract emails and their attachments from Microsoft Outlook's proprietary .msg files. It supports various MSG file formats, including embedded messages and complex structures, and can handle different encodings. The library is actively maintained with frequent minor and patch releases, currently at version 0.55.0.
pip install extract-msgVerified import paths — ran on the pinned version, not inferred.
This quickstart demonstrates how to open an MSG file, access its subject, sender, date, and body, and save any attached files. It uses a context manager (`with Message(...) as msg:`) to ensure proper resource handling.
Explicitly set `maxNameLength` in `attachment.save()` or `MessageBase.save()` methods if you require longer filenames, e.g., `attachment.save(maxNameLength=256)`.
Adjust your HTML parsing logic to account for the change to plain HTML. If prettification is desired, you may need to apply a separate HTML prettifier (e.g., `BeautifulSoup`) after extraction.
Always use the `with Message(...) as msg:` context manager pattern to ensure files are properly closed and resources are released, even if the file is a plain OLE file. If you are manually handling `MSGFile` objects, ensure `close()` is called.
Ensure your environment's locale settings are appropriate for the expected encodings. Report specific malformed files to the library maintainers if issues persist after updating to the latest version. The library continuously improves its handling of diverse encodings.
Install the library using pip: `pip install extract-msg`
Use the `openMsg` function instead: `import extract_msg; msg = extract_msg.openMsg('path/to/your/file.msg')`When opening the message, specify the correct encoding if known, or try common encodings like 'latin-1' or 'cp1252'. You can also use error handling to ignore problematic characters: `msg = extract_msg.openMsg('path/to/file.msg', overrideEncoding='cp1252', errors='ignore')` or `msg = extract_msg.openMsg('path/to/file.msg', errors='replace')`While direct support for all container types might not be implemented, you can handle this by wrapping the attachment extraction in a try-except block to skip unsupported attachments: `for attachment in msg.attachments: try: attachment.save() except NotImplementedError: print(f'Skipping unsupported attachment: {attachment.longFilename}')`No dependency data recorded yet.
