Aspose.Email

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. ...

Aspose.Email FOSS for Python provides a complete toolkit for MSG, CFB, and EML processing: high-level MapiMessage creation, low-level MsgReader inspection, CFB container traversal, EML conversion, and attachment handling — free, MIT-licensed, no Office dependency.

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.

Aspose.Email FOSS for .NET is a free, MIT-licensed C# library for reading, creating, and processing Outlook MSG files, CFB containers, and EML messages without Microsoft Outlook.

Aspose.Email FOSS for Python is a free, MIT-licensed library for creating, reading, and converting Outlook MSG files in pure Python.
