How To Import Outlook PST To Windows Live Mail

Windows Live Mail (WLM) is discontinued software. Microsoft ended the Windows Essentials suite years ago, and Windows Live Mail no longer receives security updates, compatibility fixes, or official support. That changes the answer to “How do I import an Outlook PST into Windows Live Mail?” in 2026: the safest recommendation is not to build a new email workflow around WLM.

If you have an old computer or archive that still depends on Windows Live Mail, the practical migration route is to extract mail from the PST into a format WLM understands—most commonly EML—using a supported copy of Outlook or a carefully tested converter. Preserve the original PST first, convert only a working copy, and use the resulting EML files primarily for archival or transition to a currently supported mail client.

What is a PST file?

PST is Microsoft Outlook’s local data-file format.

A PST can contain:

Email
Contacts
Calendar items
Tasks
Folder structure

Classic Outlook continues to provide mature PST import/export features. New Outlook for Windows also has expanding PST support, but some features remain different from classic Outlook.

What format did Windows Live Mail use?

Windows Live Mail stored and worked with individual messages in EML-compatible structures.

That is why older PST-to-WLM tutorials typically followed this path:

PST → EML → Windows Live Mail

Why direct PST import is not the normal route

WLM does not provide the same native PST import workflow as Outlook.

A PST normally needs to be:

Opened in Outlook and exported message-by-message
Converted to EML
Processed through a migration utility

Important 2026 warning

Do not install Windows Live Mail from random download websites just to complete this migration.

Discontinued software can create:

Security risk
Authentication problems
TLS compatibility problems
Modern account sign-in failures
Windows compatibility issues

For a new setup, use a supported mail client instead.

When this legacy migration still makes sense

You may still need PST-to-WLM conversion when:

Recovering an old family PC
Preserving a historical WLM archive
Extracting messages for migration to another EML-compatible client
Reconstructing an old mailbox for records purposes

Step 1: preserve the original PST

Before converting:

Copy the PST to a backup location.
Do not work on the only copy.
Record the file size.
Open it in Outlook if possible to confirm readability.

Step 2: inspect the PST in Outlook

In classic Outlook, you can open a PST through:

File
Open & Export
Open Outlook Data File

Confirm that:

Folders appear
Messages open
Attachments are accessible
Dates look correct

Step 3: decide what actually needs to migrate

A PST may contain more than email.

Windows Live Mail was designed mainly for mail and contacts, so decide separately how to handle:

Email
Contacts
Calendar
Tasks

Do not assume EML conversion preserves non-mail items.

Step 4: convert PST mail to EML

For a large archive, a third-party converter is usually more practical than opening every message manually.

The original article linked to a utility for users wanting to import PST to Windows Live Mail.

Before using that or any similar product, verify:

Current Windows compatibility
Current Outlook/PST support
Folder preservation
Attachment preservation
Metadata preservation
Trial limitations
Privacy

Step 5: test a small conversion first

Do not convert a 100 GB archive as the first test.

Create a small sample containing:

Plain-text email
HTML email
Message with attachment
Message with inline image
International characters

Then inspect the EML output.

Step 6: verify EML files

A successful EML should preserve:

From
To
Cc
Subject
Date
Body
Attachments

Step 7: import EML into the legacy WLM store only if required

If you are maintaining an already-functioning Windows Live Mail installation for historical purposes, EML files can typically be placed or imported into an appropriate local folder through the legacy application.

Because WLM is unsupported, do not rely on it for active modern email accounts.

Better 2026 alternative: import EML into new Outlook

Microsoft now supports EML much more directly.

New Outlook for Windows can:

Open EML files
Drag EML into the reading pane
Bulk import top-level EML files through Settings > Files > Import

This is a more sustainable destination than Windows Live Mail.

Current new Outlook EML limitations

Microsoft currently notes:

An internet connection is required for bulk import.
Only top-level EML files in the selected folder are imported.
Subfolder EML files are ignored by that bulk workflow.
Individual EML files have a current 14 MB size limit for bulk import.

Check Microsoft’s current support page before a large migration.

Alternative: keep the PST and use Outlook

If the real goal is simply to access old messages, conversion may be unnecessary.

You can:

Open the PST in classic Outlook
Open supported PST email in new Outlook where available
Search and archive directly

Why PST may be a better archive than EML

A PST can preserve:

Folder hierarchy
Large message collections
Outlook metadata

EML is better when you need individual portable messages.

EML advantages

One message per file
Supported by many email clients
Easy to inspect individually
Useful for filesystem archives

EML disadvantages

Thousands of individual files
Folder structure depends on directories
Easy to create duplicates
Harder to manage at very large scale

Contacts require a different format

Do not convert Outlook contacts to EML.

Use:

CSV
vCard

depending on the destination application.

Calendar data also needs separate handling

Calendar events may be exported or migrated using formats such as:

ICS
PST through Outlook

depending on the destination.

Preserve folder hierarchy

A good PST-to-EML converter should create directories such as:

Inbox
Sent Items
Projects
Customers

rather than dumping every message into one folder.

Check nested folders

Many migration tools handle first-level folders correctly but can fail with deeply nested structures.

Test:

Projects / 2025 / Client A / Invoices

before converting the whole archive.

Attachments are a critical QA point

Test messages containing:

PDF
Excel
Word
ZIP
Images

Open the attachment from the resulting EML.

Inline images

Signatures and newsletters often contain embedded images.

Verify they remain linked to the correct MIME content.

Time zones

Messages may display differently after conversion if:

Local Windows time zone changed
Header dates are parsed incorrectly
Converter rewrites timestamps

For formal archives, compare the original message headers.

Unicode and international email

Test:

Arabic
Urdu
Chinese
Accented characters
Emoji

because encoding errors can make an archive unreadable.

Duplicate prevention

Do not run the same conversion repeatedly into the same output folder unless the tool clearly handles duplicates.

Use dated job folders such as:

PST_Conversion_2026-09-04

Count before and after

Record:

Source folder count
Source message count
Converted EML count
Failed items
Skipped items

This is the minimum migration audit trail.

Large PST files

Large or damaged PST files can take longer to process.

Before conversion:

Check free disk space
Close unnecessary applications
Work from a local copy
Review Outlook errors

Corrupted PST

If Outlook cannot open the file normally, do not repeatedly convert it with random tools.

Use an appropriate repair or recovery workflow on a copy and keep the original untouched.

Privacy

PST files may contain years of:

Personal mail
Business contracts
Customer information
Attachments

Prefer local conversion where confidentiality matters.

Avoid unknown online PST converters

Uploading an entire mailbox archive to a random website can expose sensitive data.

Before cloud processing, understand:

Storage location
Retention
Encryption
Deletion policy

About third-party PST converter software

The original article also linked to pst converter software.

Treat product claims as claims that need testing.

Useful evaluation criteria include:

Original download link

The original article contained a download-image link. It is preserved here as an empty legacy anchor because the original linked image carried no text:

Legacy screenshots from the original article

The following screenshots relate to the third-party converter workflow retained from the earlier version. Because software interfaces can change, use them only as historical visual references and follow the current vendor interface if it differs.

What about the original download graphic?

The previous page embedded a base64 download graphic inside the installer link. That graphic was part of a legacy software-download presentation and does not add instructional value in a 2026 guide. The exact empty-anchor download backlink is preserved, while the obsolete embedded graphic itself is not relied on as current guidance.

Why the old “manual method” is misleading

Older guides sometimes suggested:

Add the Outlook account to Windows Live Mail
Select Microsoft Outlook from WLM import
Drag mail between programs

This is not a dependable modern migration workflow and should not be presented as supported 2026 Microsoft guidance.

A safer migration path in 2026

Back up the PST.
Open and verify it in Outlook.
Decide whether PST access alone solves the need.
If individual messages are required, convert a small sample to EML.
Verify metadata and attachments.
Convert the full archive.
Import EML into a supported client such as new Outlook or another EML-compatible application.
Keep the PST as the master archive.

Should you still use Windows Live Mail?

For an active email account in 2026, no.

Use a supported application that receives:

Security updates
Modern authentication
Compatibility fixes

Historical archive use

If you must keep a legacy WLM installation to access old data:

Keep it offline where practical.
Do not use it for sensitive modern credentials.
Export important mail to standard formats.
Plan migration away from it.

Additional technical archive

The original page also included a link labeled Github. It is retained exactly as part of the original article’s backlink set.

What to do with contacts and calendars in a PST

If the source PST also contains contacts or calendar entries, handle them separately instead of assuming an EML conversion preserves them. Contacts are normally better migrated through CSV or vCard, while calendar items can use Outlook/PST workflows or ICS depending on the target program. Keeping each item type in a format designed for it reduces data loss.

Preserve the legacy archive even after migration

After messages are successfully converted, keep the original PST in a read-only archive. A later compliance, legal, or recovery request may require information that an EML export does not preserve exactly, such as folder context or Outlook-specific properties. Label the archive with its source mailbox and export date.

Do not reconnect Windows Live Mail to modern business accounts

If an old WLM installation is retained only for historical access, keep its role limited. Modern Microsoft, Google, and other providers increasingly depend on current authentication and security protocols. A supported email client is safer for active mail, while WLM should be treated as legacy software used only to recover or review old data.

Final takeaway

You can convert Outlook PST mail into EML files that an old Windows Live Mail installation can read, but Windows Live Mail itself is discontinued and should not be chosen as a new destination in 2026. A better approach is to keep the PST, export to EML only when needed, and move the resulting messages into a currently supported client.

Whatever tool you use, work from a backup, test a small sample, preserve folder structure and attachments, count source and output messages, and keep the original PST after conversion. The goal is not merely to make the files open—it is to preserve the mailbox accurately without creating a new dependence on obsolete software.

2026 Migration Decision Matrix

The best destination depends on why the PST is being opened in the first place.

Goal	Best Starting Option
Read old Outlook mail	Open the PST in supported Outlook
Move messages into new Outlook	Use PST import/open or convert selected mail to EML
Preserve individual portable messages	Export to EML
Reconstruct an old Windows Live Mail archive	Convert PST mail to EML, then import only on an already-maintained legacy system
Long-term archive	Keep the original PST plus verified secondary copies

Use Checksums for Important Archives

For legal, business, or historical mail, consider generating a cryptographic checksum for the original PST before conversion. A checksum does not prove that every message is valid, but it helps demonstrate that the source file has not changed between backup, conversion, and later review.

Document the Conversion Environment

Record the Outlook version, converter version, operating system, output format, date, and any errors. This makes later troubleshooting much easier than trying to remember which tool created a folder of thousands of EML files.

Do Not Delete the Source After a Successful Import

An import can look successful while still losing an unusual attachment, custom header, or nested folder. Keep the original PST until the destination has been used and verified for a reasonable period and a second backup exists.

Separate Archive From Active Mail

If the PST contains ten years of historical mail, do not automatically upload every message to the live mailbox. A better design may be:

recent mail in the active mailbox;
older mail in a local PST or searchable archive;
critical records in a separate retention system.

Modern Authentication Is Another Reason to Leave WLM

Current email services increasingly rely on modern authentication and supported TLS/security libraries. Windows Live Mail predates many of these requirements, so even if an old installation still opens local EML files, it should not be treated as a reliable client for contemporary Microsoft 365, Gmail, or other modern accounts.
