Data has many lives, and email files are no exception to them. An Outlook OST, which may just be presented as an email copy at the beginning, may be completely locked inside due to a server crash or account deactivation. When you convert OST to Text, it breaks open that locked vault, providing complete access to your Outlook emails, contacts, calendars, and more. It doesn’t consume more storage, can be easily searched and read on any device with ease. This blog elaborates on the free method and a reliable OST to PST Converter for handling archives efficiently.
“As CIO of a Fintech firm, we’re converting legacy Outlook OST archives to TXT for Azure compliance amid CCPA audits. With 500 GB of data, I need reliable and verified solutions to save OST emails as TXT file while ensuring high data integrity and benchmark zero-downtime and loss.”

To understand the conversion needs, we must first learn about the specific file formats. The difference table below will give clarity on OST and TXT.
|
Outlook Storage Table (OST) |
Text (TXT) |
|
A structured and proprietary Outlook file format storing mailbox data for offline use |
An unstructured, universally readable plain text format holding email content for reading, indexing, and analysis. |
|
Is only compatible with MS Outlook |
Can be viewed with any Text Editor |
|
Stores and preserves folder, metadata, and HTML attachments |
Contains only message bodies with basic headers and no attachments |
|
Contains everything in the original format and takes up more space |
Save everything as raw data, which is lightweight with less storage |
Thus, this defines that OST files are not built for manual extraction, portability, or use outside Outlook/Exchange. These cache copies of mailbox data can only be useful for compliance, offline portability, or documentation when saved as TXT.
Two free solutions can be used for the manual OST to TXT conversion, depending on the number of files and the time you have.
Note: This approach is useful to save individual OST emails directly through Outlook.
Note: It is the easiest and simplest method to retain the email body content and save data as Text.
The MailConverterTools OST to PST Converter easily handles bulk conversion for large email volumes with attachments. It preserves the email formatting and even allows you to save attachments separately (if required). Additionally, the folder hierarchy is maintained, and the process is quick and efficient with various advanced capabilities. Moreover, it offers a demo version to save upto 50 emails as TXT per folder for free and without any hassle.

Real World Scenario:
A paralegal team had 18 GB OST archives from an inactive employee. Outlook couldn’t open due to the removal of the original file. Using the OST to TXT Converter, they securely exported only the email body content required for case documentation. It almost created 2200 TXT files, keeping the folder structure preserved without Outlook reliance. That’s the kind of efficiency businesses depend on today for continuity and growth.
The file format conversion provides a simple, portable, and cross-platform way of accessing your email’s contents. Whether it is for compliance, documentation, migration, or archival purposes, manual export methods are good when you need to perform an initial export. However, using professional MailConverterTools OST Converter offers greater accuracy, speed, and dependability to convert OST to Text for your business workflow. Thus, providing immediate access to your OST data without any restrictions by Outlook.
Ans. An individual needs to access Outlook for manual export. Whereas the OST to PST Converter works without Outlook and directly saves all data in TXT in one go.
Ans. Yes! Automated MailConverterTools OST to PST Converter Tool allows for batch processing and bulk exporting of entire mailboxes into TXT file format.
Ans. Originally, the TXT file format preserves the body content of the email message, the email subject line, the sender and receiver’s details, and other metadata associated with the message. But attachments are not included within the TXT file. With the converter tool, you can choose to save attachments in a separate directory.
Ans. The MailConverterTools OST to PST Converter is best as it supports all Outlook versions of OST files and allows bulk exporting, to ensure that all exported emails are accurate and safe.
