User Query: I have many emails saved in EML format from different email clients. I now need to open and manage these emails in Microsoft Outlook, which supports MSG files. What is the best and safest way to convert EML to MSG without losing email data, attachments, or formatting?
Introduction: Emails are a key part of daily communication for both individuals and businesses. Over time, users collect emails from different platforms such as Thunderbird, Apple Mail, or other clients that store messages in EML format. However, Microsoft Outlook uses the MSG format to save emails. Because of this difference, EML files do not open directly in Outlook. This creates a common need to convert EML file to MSG. The goal is simple. Keep emails readable, attachments safe, and the original structure intact. In this blog, we will explain the best DRS Softech EML Converter Tool for 100% accurate conversion.

- Choose “Select Files” or “Select Folder” to add your EML files.
- Preview and select the EML emails to convert. Click Next.
- Pick MSG as the Saving Format from the given list.
- Apply advanced features as per your needs. Hit Convert.
Real-Life Scenario: How the Tool Helped a Business Analyst
A small business moved its email system to Microsoft Outlook. Old emails were stored in EML format. Manual conversion took too much time. Some attachments were lost. After using a professional EML to MSG converter, all emails were converted successfully. Folder structure remained the same. Work continued without interruption.
Manual Method to Convert EML to MSG [Free]
The manual method involves using Microsoft Outlook as the bridge to convert EML files into MSG format. This approach is free but has limitations when handling large numbers of emails. Here’s how to do it properly:
Step 01: Install and Open Microsoft Outlook
- Firstly, make sure you have Microsoft Outlook installed on your system.
- Open Outlook and ensure your mailbox is set up (any account works for this process).
Step 02: Locate Your EML Files
- Now, go to the folder where your EML files are saved.
- You can convert a single file, multiple files, or an entire folder, but Outlook does not allow folder-level drag-and-drop for MSG conversion.
Step 03: Drag and Drop EML into Outlook
- Next, select the EML file(s) you want to convert.
- Then, drag the file(s) directly into your Outlook mailbox or a folder within Outlook.
- This imports the email(s) into Outlook, allowing you to open them as standard messages.
Step 04: Open the EML in Outlook
- After that, double-click the email in Outlook to open it.
- Ensure that the email content, attachments, and formatting appear correctly.
Step 05: Save the Email as MSG
- With the email open, go to File → Save As.
- In the Save as type dropdown, select Outlook Message Format (*.msg).
- Further, choose the folder where you want to save the MSG file and click Save.
Step 06: Repeat for Multiple Emails
- If you have more EML files, repeat steps 3–5 for each email.
- Note: Outlook does not support batch conversion in the manual method. Converting hundreds of emails can take a long time.
Limitations of the Manual EML to MSG Conversion
- Time-consuming: Converting large numbers of emails individually takes hours.
- No batch processing: You must convert each EML file separately.
- Risk of missing attachments: Drag-and-drop or save errors can result in missing files.
- Prone to human error: Manual steps can lead to skipped emails or incorrect saves.
- Not suitable for business use: If you have hundreds or thousands of emails, this method is inefficient.
