Email migration has become a common requirement for businesses, IT administrators, and individual users. Many organizations still have years of email archives stored in EML files created by email clients such as Windows Live Mail, Outlook Express, Thunderbird, Windows Mail, and other applications.
The challenge begins when users need to move these emails into Microsoft Outlook. Outlook does not provide a direct method to import thousands of EML files while maintaining folder structure, attachments, metadata, and email formatting.
This is where a professional EML to PST Converter becomes important.
A reliable converter does more than simply change file extensions. A good tool should maintain:
- Original email formatting
- Sender and recipient information
- Attachments
- Folder hierarchy
- Email dates
- HTML content
- Metadata
- Data integrity
However, choosing the right software is not easy. The market has many tools claiming to be the best EML to PST Converter, but their performance differs significantly when handling large mailboxes, corrupted files, bulk conversion, and enterprise migration.
In this detailed review, we tested and analyzed the top EML to PST conversion software available for 2027 based on:
- Conversion accuracy
- Speed performance
- Feature availability
- Pricing
- Ease of use
- Customer feedback
- Reliability for IT administrators
After comparing multiple solutions, Shoviv EML to PST Converter ranks at the top because of its combination of accuracy, enterprise features, and flexible migration options.

What Should You Look For in an EML to PST Converter?
Before selecting any tool, it is important to understand what separates a professional converter from a basic file conversion utility.
1. Data Accuracy
The most important factor is accuracy.
A converter should create PST files that open correctly in Microsoft Outlook without missing:
- Attachments
- Images
- Formatting
- Email headers
- Folder structure
A tool that converts emails but damages important information is not useful for business users.
2. Bulk Conversion Capability
Manual conversion is impossible when dealing with thousands of EML files.
Professional software should support:
- Multiple EML files
- Complete folders
- Multiple user mailboxes
- Large email databases
3. Folder Hierarchy Maintenance
Business users usually organize emails into folders.
A good converter should preserve:
Inbox → Client Folder → Project Folder → Emails
Without this, migrated emails become difficult to manage.
4. Migration Options
Modern businesses use Microsoft 365 and Exchange Server.
Therefore, advanced tools should support:
- PST export
- Office 365 migration
- Exchange Server migration
- Outlook profile export
5. Performance With Large Data
A reliable EML to PST Converter should handle:
- Thousands of emails
- Large attachments
- Multiple folders
- Long conversion sessions
without crashing.

Key Features of Shoviv EML to PST Converter
1. Bulk EML to PST Conversion
One of the strongest advantages of Shoviv is bulk processing.
Users can add multiple EML files and folders together instead of converting emails individually.
This feature is especially useful for:
- IT administrators
- Businesses
- Data migration companies
For organizations managing multiple employees’ email archives, bulk processing saves significant time.
2. Maintains Original Folder Structure
During email migration, maintaining organization is critical.
Shoviv keeps:
- Folder hierarchy
- Email properties
- Attachments
- Formatting
after conversion.
This means users receive a PST file that looks similar to the original mailbox structure.
3. Multiple Export Formats
Many converters only support PST export. Shoviv provides additional options. Users can convert EML files into:
- PST for Outlook
- MSG for individual emails
- PDF for documentation
- HTML for browser access
- ICS for calendar data
- VCF for contacts
This flexibility makes the tool useful beyond Outlook migration.
4. Microsoft 365 and Exchange Migration
A major advantage for businesses is direct migration support. Shoviv allows users to export EML files directly into:
- Microsoft 365 mailboxes
- Exchange Server
- Outlook profiles
This reduces additional migration steps.
5. Advanced Filtering Options
Large email archives often contain unnecessary data. Shoviv allows selective conversion using filters based on:
- Date range
- Sender
- Recipient
- Subject
- Email fields
For example:
An administrator can migrate only emails from January 2024 to December 2025 instead of processing the entire archive.
6. Attachment Extraction
Attachments are often the most important part of business emails. The software can extract attachments separately and save them into a selected folder.
This is useful for:
- Legal teams
- Accounting departments
- Project documentation
7. Incremental Export
A unique feature is incremental export. If the conversion process stops because of:
- System restart
- Network issue
- Large data volume
the tool can continue without starting from zero. This helps avoid duplicate conversion.
