OST to PST Converter

This tool converts Outlook OST data to PST format using a file-based workflow. It accepts an OST input and produces a PST output while preserving mailbox structure and item metadata. The core logic reads the OST container, reconstructs folders, and exports emails, contacts, calendars, and attachments into a PST, enabling offline access or migration. It supports optional password-protected OSTs by decrypting with a provided password, and can perform selective exports (e.g., specific folders or items) via advanced options. The tool is designed for IT admins, helpdesk staff, and end users who need to migrate or recover mailbox data without a live Exchange connection. Unique value lies in maintaining data fidelity during conversion, including complete metadata, folder hierarchy, and attachments, and in handling common OST edge cases such as corrupted items or very large files. Use cases include pre-migration archiving, mailbox recovery after profile corruption, and decommissioning legacy OST-based workflows. Core features include: OST input handling, PST output generation, optional decryption, preservation of mailbox structure, attachment export, and detailed export reporting. This approach reduces downtime, accelerates data access, and simplifies archival and discovery workflows. The tool operates locally or server-side depending on deployment and does not rely on user email server availability, ensuring access to mailbox data during outages or transitions.
