Key Concepts

A PST file is a single-user database that stores email messages, contacts, and calendar information. It is typically used for storing data in a personal folder or profile.

PST conversion involves converting the data stored in the .pst file to a different format or platform, such as Office 365 or a competing email client like Apple Mail.

Types of PST Conversion

• Manual Conversion: Manual conversion involves manually transferring data from one PST file to another using specialized tools or software.
• Automated Conversion: Automated conversion uses software or services that can automatically convert PST files without manual intervention.
• Batch Conversion: Batch conversion involves converting multiple PST files at once, often used for large-scale migrations.

PST files use a proprietary format developed by Microsoft. The file format consists of several sections, including the header, message stores, and data streams.

The file format is typically stored in a single file with a .pst extension.

PST File Structure

• Header: Contains metadata such as the file name, version number, and timestamp
• Message Stores: Stores email messages, including headers, body text, attachments, and other properties
• Data Streams: Stores various data streams, such as contacts, calendar information, and task lists
