ZOOK EML to MSG Converter Review: Features, Pros & Cons

How to Use ZOOK EML to MSG Converter: A Step-by-Step GuideConverting EML files (commonly used by email clients like Windows Live Mail, Thunderbird, and Apple Mail) to MSG format (used by Microsoft Outlook) can be essential when migrating mailboxes, sharing messages with Outlook users, or preserving metadata and attachments. This guide walks you through using ZOOK EML to MSG Converter with clear, step-by-step instructions, practical tips, troubleshooting advice, and best practices for batch processing and preserving data integrity.

What is ZOOK EML to MSG Converter?

ZOOK EML to MSG Converter is a desktop tool designed to convert EML and EMLX email files into MSG format. It simplifies migration to Microsoft Outlook by preserving email headers, body content, attachments, embedded images, and metadata (such as sender, recipient, date, subject). The software typically supports batch conversion, filters, and maintains folder hierarchy during export.

Before you start: Requirements and preparation

• System: Windows OS (usually Windows 7/8/10/11) — confirm the exact supported versions on ZOOK’s website.
• Email clients: You should have the EML/EMLX files exported or accessible.
• Storage: Ensure enough disk space for output MSG files.
• Outlook: If you want to directly open or import MSG files, have Microsoft Outlook installed.
• Backup: Create a backup of original EML files before converting.
• Licensing: Obtain and activate the ZOOK EML to MSG Converter license if using a paid version.

Installation and setup

1. Download: Visit ZOOK’s official site and download the EML to MSG Converter installer.
2. Run Installer: Double-click the downloaded .exe and follow the on-screen prompts. Accept the license agreement and choose installation location.
3. Launch: Open the application from the Start menu or desktop shortcut.
4. Activate (if needed): Enter your license key via the software’s Help or About > Activate section.

Step-by-step conversion

1. Add EML files or folders

   • Click the “Add File” or “Add Folder” button.
   • To convert many emails at once, choose the parent folder containing subfolders of EML/EMLX files. The tool preserves folder structure during export.

2. Preview emails (optional)

   • Select an individual EML file in the list to preview its content and attachments. This helps verify you selected the correct files.

3. Apply filters (optional)

   • Use available filters (date range, sender, subject keywords) to limit which messages are converted. This is useful for partial migrations.

4. Choose output location and options

   • Specify the destination folder for MSG files.
   • Select options like “Maintain folder hierarchy,” “Export attachments,” or encoding preferences if available.

5. Start conversion

   • Click the “Export” or “Convert” button. Monitor progress in the status bar. Batch conversions may take longer depending on file count and sizes.

6. Verify results

   • Open a few converted MSG files with Microsoft Outlook to confirm message content, attachments, and metadata are intact.

Batch conversion and preserving hierarchy

• For large mailboxes, add the top-level folder containing all EML subfolders.
• Ensure the “Maintain folder hierarchy” option is checked to keep the original organization.
• Run conversions during off-hours to avoid system performance impacts.

Troubleshooting common issues

• Missing attachments after conversion: Ensure the “Export attachments” option is enabled. Re-run conversion for affected files.
• Corrupted MSG files: Verify source EML files are not corrupted. Try converting a single EML to isolate the issue.
• Conversion fails for some files: Check file permissions and remove read-only attributes. Run the app as Administrator.
• Outlook cannot open MSG: Confirm Outlook version compatibility and that MSG files are not blocked by file properties (right-click > Properties > Unblock if present).

Tips & best practices

• Backup originals before converting.
• Test with a small subset of EML files to confirm settings.
• Keep software updated to latest version for bug fixes and compatibility.
• Use filters to reduce conversion time and output size.
• If migrating to an Exchange/Office 365 environment, consider importing MSG files into Outlook and then into the target mailbox.

Alternatives and when to use them

• Manual import: Drag-and-drop individual EML files into Outlook (limited and time-consuming).
• Other converters: Evaluate tools by feature set (batch support, folder preservation, attachment handling) and price.
• Professional migration services: For large-scale enterprise migrations, use specialized migration tools or services.

Final verification checklist

• Open random sample MSGs in Outlook to check content and attachments.
• Confirm folder structure preserved (if required).
• Ensure no critical emails were missed by comparing counts between source and output folders.
• Keep original EML backup for at least one migration cycle.
