The migration and archiving of email data remain critical challenges for organizations aiming to maintain compliance and ensure long-term data accessibility. The Personal Storage Table (PST) file format, proprietary to Microsoft Outlook, presents significant interoperability issues due to its complex binary structure and dependency on the MAPI (Messaging Application Programming Interface). This paper explores the necessity of converting PST files to the Portable Document Format (PDF), an ISO-standardized open format. It analyzes the technical hurdles of parsing PST binary streams, discusses strategies for preserving email metadata and attachments, and proposes a software architecture for an efficient PST-to-PDF converter.
