  • Data Backup & Archiving functions occur when PST file conversion produces formats like PDF or MBOX which allows for long-term data storage and convenient access.
  • Legal and organizational policies together with compliance requirements may necessitate PST file conversion.
  • Users who want to share particular emails for documentation need to extract these messages from PST files into EML or MSG formats.
