Introduction: PST (Personal Storage Table) is the primary file format used by Microsoft Outlook. It is used to store mailbox data such as emails, contacts, calendars, tasks, and attachments. Many businesses and professionals use PST files for backups and long-term email storage. MSG, on the other hand, is an individual email file format used by Outlook to store single email messages. Converting PST to MSG helps users save specific emails as separate MSG files for legal records, documentation, or easy sharing. In this guide, we will explain simple and automated methods to convert PST to MSG files using the MacSonik PST Converter Tool.

Real-Life Scenario: Legal Email Documentation
A legal consultant needed to extract over 850 case-related emails from a 14 GB PST file for compliance and legal documentation. These emails included contracts, client communications, court notices, and more than 1,200 attachments. Since around 75% of these emails were linked to active cases, preserving metadata was critical. The manual drag-and-drop method was too slow and risky, taking nearly 8–10 hours for completion. Using the PST Converter Tool, all selected emails were converted into MSG format, with complete attachments and metadata preserved.
