Aspose.Email

A free, MIT-licensed C++17 library for reading, creating, and converting Outlook MSG, EML, and CFB files — no external runtime dependencies, added to any project as a CMake subdirectory.

Aspose.Email FOSS for Python is a MIT-licensed library for MSG, EML, and CFB file processing. It provides MapiMessage for creating and reading Outlook messages and CFBReader/CFBWriter for low-level compound file storage access.

Introduction Parsing email messages programmatically is a common requirement for archival tools, compliance pipelines, and migration utilities. Outlook MSG files use the Compound File Binary (CFB) container format with MAPI property streams, while EML files follow the MIME standard. Both formats require careful handling of encodings, folded headers, and nested attachments. Aspose.Email FOSS for .NET is a free, MIT-licensed C# library that provides a complete read-write API for MSG and EML messages. It targets .NET 8.0+ and has no dependency on Microsoft Outlook or any native COM interop layer. The library is available as the aspose.email.foss NuGet package. ...

Introduction Parsing email messages programmatically is a common requirement for data migration, archival workflows, and compliance tools. Outlook MSG files use the Compound File Binary (CFB) container format with MAPI properties to encode message metadata, body content, recipients, and attachments. Working with this format in Python has traditionally required either commercial libraries or low-level binary manipulation. The aspose-email-foss package provides a pure-Python, MIT-licensed library for reading, creating, and converting Outlook MSG files. It exposes a high-level MapiMessage API for common tasks alongside lower-level MsgReader access for detailed inspection of the underlying CFB structure. The library requires Python 3.10 or later and has no native dependencies. ...

Read, create, and convert Outlook MSG files in C++17 with no external dependencies. Aspose.Email FOSS for C++ is MIT-licensed and works on Linux, macOS, and Windows.
