Beryl.Outlook 2.1.1

Beryl.Outlook for .NET (.NET Standard 2.0 to .NET 10.0+)

Enterprise Advanced Outlook PST and OST Recovery, Deep Forensic Analysis, and Mailbox Reconstruction Engine for .NET.

Beryl.Outlook is an industry-leading, high-performance forensic and recovery SDK engineered by Data TB Software. Designed for enterprise software vendors, forensic investigators, eDiscovery platforms, and system administrators, Beryl.Outlook provides low-level binary parsing and repair capabilities for Microsoft Outlook data files (.pst and .ost).

Operates 100% independently: No Microsoft Outlook, Office, or MAPI installation is required on the server or client machine.

Why Choose Beryl.Outlook?

1. Advanced Corrupted PST and OST Repair

Standard tools like Microsoft ScanPST.exe frequently truncate corrupted records or fail when encountering severe database structure corruption. Beryl.Outlook bypasses corrupted indexes and parses raw Node Database (NDB) and Logical Table Primitive (LTP) layers directly, allowing successful recovery from critical Outlook errors including 0x80040119, 0x80040600, and oversized file corruption.

2. Zero-Header Mailbox Rebuilding

If the initial 2048-byte PST header is corrupted, zeroed out, or overwritten by malware or disk failure, conventional parsers crash. Beryl.Outlook contains an intelligent heuristic B-Tree reconstruction scanner that sweeps the binary payload, locates orphaned block descriptors (BBTs) and node descriptors (NBTs), and reconstructs the complete mailbox hierarchy from scratch.

3. Forensic Slack Space and Deleted Item Carving

When an email is permanently deleted (Shift+Delete) or purged from the "Deleted Items" folder, Outlook marks the associated database block as unallocated slack space without immediately wiping the underlying bytes. Beryl.Outlook includes a specialized forensic carving engine that scans unallocated block pools to recover permanently deleted emails, contacts, calendar events, and raw file attachments.

4. Built-in Pure Unicode PST Generation

Export recovered data directly into pristine, fully compliant Microsoft Outlook Unicode PST files compatible with Outlook 2003, 2007, 2010, 2013, 2016, 2019, 2021, 2024, and Microsoft 365. The PST generator is self-contained and does not rely on third-party drivers or Windows COM automation.

5. High-Performance Independent Architecture

Engineered from the ground up for maximum throughput and minimal memory footprint, Beryl.Outlook utilizes native memory streaming, zero-copy buffers, and SIMD vectorization. Process massive multi-gigabyte mailboxes with predictable, flat memory consumption.

Universal Target Framework Support

Beryl.Outlook is compiled with multi-target support to ensure seamless drop-in compatibility across legacy enterprise systems and modern cloud-native architectures:

Cross-Platform Compatibility: Fully supported on Windows, Windows Server (2016 through 2025), Linux (Ubuntu, Debian, RHEL, CentOS, Alpine), macOS (Apple Silicon M-series and Intel), and containerized deployments (Docker, Kubernetes).
