When managing corporate emails, especially in Microsoft Exchange and Outlook environments, encountering OST (Offline Storage Table) files is a daily routine. But when a need arises to access or migrate data from OST to other formats, such as EML (Electronic Mail Format), many IT professionals and email administrators find themselves in a challenging position.

Whether you're archiving emails, migrating platforms, or recovering data from an orphaned OST file, knowing how to convert OST to EML is crucial. In this article, we'll explain the easiest way to convert OST file to EML, introduce a powerful tool from MyDigiSoft, and explore why this conversion is often necessary.



Why Convert OST to EML?

Before jumping into the solution, let's understand the reasons behind converting OST files to EML:

  • Email Portability: EML files are supported by multiple email clients such as Windows Live Mail, Thunderbird, Apple Mail, and more.

  • Data Recovery: Recovering specific emails from corrupted or orphaned OST files is easier in EML format.

  • Migration Requirements: If you're moving to a platform that doesn't support OST or PST formats, converting OST to EML is essential.

  • Email Backup and Archival: EML format is ideal for archiving individual messages with attachments and metadata intact.

Challenges in Converting OST Files Manually

Manual methods for converting OST files often include importing OST into Outlook and then using drag-and-drop techniques or exporting via Outlook. However, these approaches have serious limitations:

  • Requires a configured Outlook profile.

  • Cannot convert orphaned or corrupted OST files.

  • No batch conversion support.

  • Risk of data loss or email structure distortion.

That's why IT professionals and email admins rely on professional utilities like the MyDigiSoft OST to PST Converter, which includes robust features to save OST to EML accurately and efficiently.
