Corbett
Corbett PST to EML Converter saves Outlook PST mail as plain EML files, in bulk or for chosen items only. Folder order, attachments and data integrity stay intact, and huge PST files convert without a hitch.

EML facts
A PST file belongs to desktop Outlook, while an EML file carries one message and imports into Gmail, Yahoo, Hotmail, iCloud and Outlook. The tool connects the two with no extra software.

Why Mail Moves From PST to EML
PST is an Outlook format confined to the desktop, and no manual method moves it elsewhere. EML files import into other email applications, so the same mail works in clients beyond Outlook.
Core features
Install, add PST files, set search fields and export as EML.
Install
Get the tool from the download link and run its setup on Windows. PST files are added in the main window.
Folder selection
Load one PST file or many. Folders and items appear in source order before conversion starts.
Message preview
The preview opens every email in full, so admins can check the data before the EML run.
Selective backup
Use fields like name, subject and To or From to find mail inside the PST, then convert only the matched items.
Output options
Click Export, choose EML and start the process. Every message becomes its own EML file on the local drive.
Before converting
Three simple checks avoid trouble later.
Source file
Make a PST copy
Close Outlook and back up the PST file on a safe drive before the EML run starts.
Item scope
All mail or chosen items
Convert every folder at once, or limit the run to contacts, addresses or attachments when only those are needed.
Target disk
Leave space for EML files
One EML file is created per email, so thousands of messages need a destination disk with free room.
Source PST handling inside Outlook is covered in Open PST file and Import PST to Outlook.

I wanted to convert all the PST files into EML format so that it can be used in other email applications also. Since PST is a format of an Outlook application and is confined to desktop only. I was looking for an alternative option and found it was not possible manually. On recommendation, I used the Corbett software PST to EML conversion tool and i am quite satisfied with it.
This tool is a very useful automated tool. I had thousands of mails to be converted into EML format and in just few simple steps I got the desired results. I have recommended the tool to my colleagues too.
I am very happy with the software. I belong to non-IT field and perhaps had to keep a backup of my files into Eml format. It was quite challenging but when I tried the automated tool, I found it simplified and easy to use without any hassles.
