Aspose.Email FOSS
Read, create, and process Outlook MSG files, CFB containers, and EML messages — free and open-source, available for .NET, C++, and Python.
Aspose.Email FOSS is a suite of free, MIT-licensed open-source libraries for reading, creating, and processing Microsoft Outlook MSG files, Compound File Binary (CFB) containers, and EML messages, with no Microsoft Outlook dependency and no proprietary runtime required. Each edition provides low-level CFB access for traversing directory entries, reading and writing storage nodes and raw streams, as well as a high-level MAPI API (MapiMessage) for creating messages from scratch, reading subjects, bodies, recipients, and attachments, and converting between MSG and EML/MIME formats. Every library in the suite installs with a single package manager command and runs identically on Windows, macOS, Linux, Docker, and serverless.
