EML to PST Converter

About This Tool

Purpose-built converter that moves email data from EML files into PST format for Outlook. It is designed for IT admins, MSPs, and power users managing migrations, backups, or archival projects. Conceptually, the tool parses EML messages, reconstructs mailbox structure, and writes a standard PST container that Outlook can open. The approach emphasizes data fidelity, metadata preservation, and compatibility with enterprise email governance. It supports batch ingestion, error reporting, and non-destructive preview of results before final export. Core value lies in scalability, automation readiness, and predictable outcomes across large mail stores.
Key features include file ingestion, format validation, and PST export. Optional capabilities cover bulk processing, folder mapping, and configurable rules to include or exclude specific messages or folders. It can split large PSTs by size or mailbox, preserve nested folder hierarchies, and attach rich headers for compliance. Use cases span decommissioning legacy servers, consolidating multiple mail stores, migrating to modern platforms, and creating compliant archives for legal discovery.
Reliability and integration: The tool exposes item-level status, summary metrics, and an audit trail suitable for governance reviews. It uses a PST-creation approach aligned with Microsoft schemas and preserves character encodings, timestamps, and headers. It supports automated pipelines and can operate in batch mode with resume on error. The design avoids data modification beyond format transformation, and outputs are suitable for immediate import into Outlook and related email clients.
