Top Ways to Convert EML to PST Format: Complete Guide

EML is a popular format commonly used by email clients, like Thunderbird, Apple Mail, Windows Live Mail, etc. Many backup and archive systems heavily rely on it because EML stores data cleanly as individual files. Outlook, on the other hand, maintains data in its proprietary PST file format. It keeps data organized and optimized for search indexes and long-term data archival. Furthermore, Outlook may open an EML file, but it cannot handle it in bulk. Thus, this blog defines ways to convert EML to PST securely for free or by using an EML to PST Converter Tool without any major loss or data alterations. 

Necessity to Convert EML to Outlook PST

EML files contain single messages, but PST files are a unified storage with all the mailbox data, including contacts, calendars, and more. Some significant reasons for EML to PST conversion include: 

  • Centralizing the complete mailbox for several clients in a single profile.
  • Ensuring wide compatibility to open EML file on macOS and Windows OS.
  • Preserving attachments, mail data, metadata, and folder structure.
  • Simplifying the portability of the mailbox for enterprises and multi-user accounts. 
  • Maintaining a secure data backup to prevent data loss or theft from unforeseen situations.
  • PSTs are easier to archive, export, and use for regulatory and compliance purposes. 
  • Managing folders, categories, and flags becomes possible after exporting data as PST for access in Outlook, M365, and Exchange environments. 

So, it is required to convert emails from EML to PST to achieve a database-level container for restructuring the mailbox. It will help ensure data is easily searchable, accessible, and shareable, and that properties, metadata, and headers are preserved.
