EML to PST Converter Software for Windows

How to download and use EML to PST Converter Software

1

Add your EML files

Open the EML to PST Converter and point it at your .eml files, or at whole folder they sit in. Each .eml is one email, so a real archive is usually hundreds of them - add them all in one go.

2

They combine into one PST

There is no merge switch to think about here. Unlike a single mailbox file, loose .eml messages are always written into one PST, landing together in one Inbox folder, so you end with single archive instead of a pile of files.

3

Pick where to save

Choose a spot on your drive and start. Outlook does not need to be open for this step, and it does not need to be installed either.

4

Open the PST in Outlook

In Outlook, go to File, Open and Export, Open Outlook Data File, and pick the new .pst. The messages are there with their dates, read state and attachments, and this time they open in the reading pane.

What this EML to PST converter software does

A real Outlook PST

SoftOrbits EML to PST Converter writes a valid Unicode .pst, and we tested the result in Outlook 2016. It is a genuine Outlook data file, not a renamed file that Outlook opens half-broken.

Every field kept

Subject lines in any language, Cyrillic, CJK and emoji included, HTML and plain-text bodies, From, To and Cc, the sent and received dates, the read or unread mark, and file attachments all carry over byte for byte.

One message per file, read in bulk

An .eml holds exactly one message in MIME form, the message/rfc822 format defined back in RFC 822. The EML to PST Converter download walks a folder full of them and rebuilds each one, so a directory of hundreds of files turns into ordinary Outlook folder.

Built for Windows-family mail

It reads the .eml written by Outlook Express, Windows Mail and Windows Live Mail, and it also takes the .eml you get from a Thunderbird Save As or a webmail download original command.

Who it is for

Leaving Windows Live Mail behind

Windows Live Mail was dropped by Microsoft years ago, and it tends to misbehave once you are on Windows 11, so the mail it left on disk as .eml has to go somewhere. For most people that somewhere is Outlook.

Sitting on a folder of exported .eml

Someone handed you an export, or an old client dumped one, and now a directory holds hundreds of single messages. You want them inside Outlook without opening each file by hand.

Years of messages saved one by one

Maybe you saved the mail that mattered from webmail or Outlook Express as individual .eml files over the years. This pulls that scattered pile into one PST you can search from inside Outlook.

EML files it reads

The .eml extension turns up under several old and newer mail programs. These are the sources the EML to PST Converter Software opens:

Source	File	Comes from	Notes
Outlook Express	.eml	Microsoft Outlook Express	Saved messages from the Windows XP era client
Windows Mail	.eml	Windows Vista Mail	One file per saved message
Windows Live Mail	.eml	Windows Live Mail 2011 and 2012	Discontinued years ago, unreliable on Windows 11
Thunderbird export	.eml	Mozilla Thunderbird, Save As	A single message saved out of a folder
Webmail download	.eml	Gmail, Outlook.com, show or download original	One downloaded message off the web

Frequently Asked Questions

Can I import an EML file into Outlook directly?

Not as a folder. Outlook has no import option for .eml, and Microsoft support says the same thing: you can drag messages in one at a time, or use a EML to PST Converter Software. This tool is the converter part, turning whole folder into a .pst you open in one step.

Can I open an EML file without Outlook on Windows?

You can read a single .eml in a few free viewers, but that does not put it into Outlook, and it does not scale to a folder of them. To get the mail into Outlook you convert the .eml files to a PST and open that instead.

What is an EML file, and why can't Outlook open a whole folder of them?

An .eml is one email saved on its own - headers, body and attachments together - in the standard MIME format. Because each file is a single message, an archive is hundreds or thousands of separate files, and Outlook has no way to take them in bulk. Converting to PST is what merges them.

Can I still use Windows Live Mail on Windows 11?

In practice, not well. Windows Live Mail was discontinued years ago, and its users report it running unreliably or not at all after a move to Windows 11. Getting the old mail out as .eml and into Outlook is the usual way off it.

How do I move my Windows Live Mail email into Outlook?

Export or locate the messages as .eml files, add them to the converter, and save the PST. Open that .pst in Outlook and the old folders are readable again, with no need to keep Windows Live Mail alive just to reach them.

What program opens EML files on Windows?

A handful of mail clients and small viewers open one .eml, but none of them load a pile of them into Outlook. For that you convert the .eml files to a .pst, which Outlook opens on its own.

Can I convert a whole folder of EML files at once?

Yes, that is the whole point of it. Point it at the folder, and every .eml inside is written into one PST together. There is no per-file step and no merge box to check, because loose messages are always combined.

Does the converter upload my email anywhere?

Short answer: no. Long answer: the conversion runs on your own machine, and nothing is sent out. Online converters ask you to upload the whole mailbox first, which is a lot of private correspondence to hand to a stranger's server; here the files never leave your PC.

Will the PST open in Outlook 365 and the new Outlook?

The output is a standard Unicode PST, the same modern data file that desktop Outlook uses. We tested it in Outlook 2016, and it opens the same way in desktop Outlook through Microsoft 365. The newer web-style Outlook keeps its own limits on data files, as it does with any PST.
