Are you struggling to add EML files folder to Outlook for Mac or Outlook for Windows? You’re not alone. Many users switch between email clients like Windows Live Mail, Apple Mail, Thunderbird, or other desktop apps that store emails in EML file format. But when it comes to importing those email messages into Microsoft Outlook, problems begin — lack of direct support, formatting errors, or missing attachments.

This guide explains the best ways to add multiple EML files to Outlook — including both manual methods and a professional EML to Outlook for Mac & Windows for smooth and error-free migration.

Why Do Users Need to Add EML Files to Outlook?

Outlook is one of the leading business email clients with powerful features like cloud sync, offline access, advanced security, and Exchange compatibility. Because of this, users often migrate from other email platforms.

Common reasons include -

• Switching from other EML-based apps such as Thunderbird or Apple Mail
• Workplace transition requiring Outlook usage
• Accessing archived email backups
• Viewing downloaded emails received from digital forensics or legal departments

However, Outlook cannot directly import .eml files in bulk, which makes migration tricky.

How to Add EML Files Folder to Outlook – Manual Methods

Below are two commonly used manual methods. These may work for small-sized imports but require technical skills and may not support large EML folders.

Manual Method 1 – Drag & Drop into Outlook

This is the simplest process for Windows users:

• Open Microsoft Outlook (Windows version)
• Create a new folder in Outlook for EML import
• Select EML files from your system folder
• Drag & drop them into the Outlook folder

Limitations -

• Not available on Mac Outlook
• Works only for a few emails
• Folder hierarchy and metadata may not migrate
• Risk of attachment corruption

Manual Method 2 – Using Windows Live Mail + Outlook (Windows only)

If Windows Live Mail is installed -

• Open Windows Live Mail
• Go to File → Export email → Email messages
• Choose Microsoft Exchange as the export type
• Select your Outlook profile and export the folder

Disadvantages -

• Windows Live Mail is discontinued — hard to access
• Requires both email clients installed
• Slow and error-prone for bulk EML data

Manual methods do not work for Outlook for Mac

Outlook for Mac uses a completely different database structure (OLM/Exchange Sync), and drag & drop support is extremely limited.

That’s why most professionals prefer a secure automated solution.
