Convert OST to EML Using Mydigisoft OST to PST Converter Tool

Category: Technology | Published: September 22, 2025

Managing email data is not always simple. Outlook stores mailbox items in two formats – OST (Offline Storage Table) and PST (Personal Storage Table). While PST files can be easily imported or backed up, OST files are more restrictive. They are bound to the profile where they were created, making them hard to access if Outlook crashes, the Exchange account is removed, or the system faces corruption issues.

This is why many users look for a reliable way to convert OST to EML. Unlike OST, the EML format is widely supported by email clients such as Thunderbird, Apple Mail, Windows Live Mail, and more. Individual EML files are portable, lightweight, and perfect for sharing or archiving specific messages.

To perform this task effectively, the Mydigisoft OST to PST Converter Tool stands out as a powerful and user-friendly solution. Let’s explore why, and how you can use it to save OST file to EML with ease.

Why Choose EML Over OST?

Before diving into the tool, let’s understand why someone would want to convert OST file to EML in the first place.

  • Cross-platform accessibility: EML files can be opened in multiple email clients and even text editors.
  • Selective saving: Users can export only the important emails they want to preserve.
  • Simple migration: Moving data from Outlook to Thunderbird or Apple Mail becomes straightforward with EML.
  • Corruption protection: Converting OST to EML ensures that even if the OST gets corrupted, the email messages remain safe.
  • Lightweight and easy sharing: Since EML files store single messages, they are easy to transfer or upload.

Why Manual Methods Aren’t Enough

Some users try manual methods like dragging and dropping emails from Outlook into a folder to create EML files. But these methods come with several drawbacks:

  • Not feasible for large mailboxes.
  • No guarantee of maintaining metadata, attachments, or formatting.
  • Risk of incomplete conversion.
  • Time-consuming when handling thousands of messages.

For professionals and organizations, relying on a trusted tool is the safest approach. That’s where Mydigisoft OST to PST Converter comes in.
