Easy Ways to Convert OST to EML Format

Jul 19, 2023 | By Deepak Singh Bisht

In this digital era, emails serve as a crucial part of our daily communication, both personally and professionally. Among a variety of email clients and services available today, Microsoft's Outlook is widely used and stores its data in an OST format. The EML format, used by multiple email platforms, offers greater flexibility in contrast to OST files, which cannot be accessed outside their native system. This blog post aims to guide you through the process of converting OST to EML, thereby ensuring a smooth transition of your data across different email platforms.

Understanding OST and EML Files

The file formats used in email communication can significantly affect their flexibility and usability. MS Outlook employs OST file format for storing mailbox data. But a key limitation of OST files is that they cannot be accessed outside the system on which they were created.

On the other hand, the EML file format, used by various email clients, including Mozilla Thunderbird, MS Outlook, Windows Live Mail, Apple Mail, and more, can be accessed and used across various platforms. This makes EML files much more versatile compared to OST files.

Business Implication of OST and EML Files

In today's business environment, where flexibility and accessibility are key, the inability of OST files to be accessed outside their native system presents significant limitations. This poses challenges, especially in scenarios where employees need to access their email data from different locations or on various devices. EML files, in contrast, offer the flexibility that modern businesses require. They can be accessed easily with a email client, making them more user-friendly and versatile.

The Need for OST to EML Conversion

The limitations of OST files, coupled with the greater flexibility of EML files, often necessitate conversion from OST to EML format. The ability to open EML files easily with email clients like Outlook, Mozilla Thunderbird, and Windows Live Mail, provides users with greater accessibility and the freedom to switch between different email programs as per their requirements.
