ZOOK OST to EML Converter

Need to get your Outlook OST files into a more universal EML format? OST to EML Converter from ZOOK Software is a straightforward tool designed to do exactly that, and it keeps everything neatly organized in the process.

Think of your OST file as a packed suitcase. This tool unpacks it, carefully taking out each email and its attachments like images, Word docs, or PowerPoint presentations and places them into the standard EML format. Everything stays the same size and format, and crucially, all your original formatting is preserved. That means your email layouts, colors, clickable links, and even signatures look exactly as they did in Outlook.

Here’s what makes it handy:

It keeps your fancy HTML and RTF email formatting intact.
You can convert a whole batch of emails at once, saving you tons of time.
It works with all versions of Outlook, and you don’t even need Outlook installed on your computer to use it.
You can sort your emails before converting and it maintains your folder structure.
Runs smoothly on various Windows versions.

The batch feature is a real time saver. Instead of converting emails one by one, you can select a whole folder or multiple files at once. The software is also quite flexible, supporting different Outlook editions and operating independently.

To run it, your PC just needs a basic setup: a 1 GHz processor, at least 512 MB of RAM (1GB is better for smoother operation), and about 50 MB of free space to install the software.

A quick heads up: the free trial version lets you test the conversion, but it will only process the first 25 emails from your OST file.
