How to Import EML Files into Office 365 – Step-by-Step Guide

If you're looking to import EML files into Office 365, the easiest and most efficient method is by using the DRS Softech EML Converter Tool. This advanced utility allows you to directly upload EML emails to your Office 365 account without any data loss or technical hassles. It's especially useful for users migrating from email clients like Windows Live Mail, Thunderbird, or Outlook Express.

Import EML Files to Office 365 Using DRS Softech EML Converter Tool:

Download and install the DRS Softech EML Converter Tool on your system.
Launch the tool and click on “Add EML Files/Folders” to import your EML data.
The tool will display all loaded EML files in a structured format. Preview emails and attachments.
From the list of saving options, choose Office 365.
Enter your Office 365 credentials (email ID and app password).
Apply additional filters like Date Range, Exclude Duplicate Emails, etc., if needed.
Click on the Convert button to start the import process.

The tool ensures safe migration while preserving folder structure, metadata, and attachments. It's compatible with all Windows versions and supports bulk EML import.

Manual Method to Import EML to Office 365:

The manual process involves multiple steps and third-party tools like Outlook and PST migration:
Open EML files using Outlook (drag and drop into a configured Outlook folder).
Once added, export the mailbox to a PST file via File > Open & Export > Import/Export.
Use Microsoft’s Network Upload method or Azure AzCopy Tool to upload the PST to Office 365.
Map the PST to the correct mailbox using Microsoft Purview Compliance Portal.

This manual method is time-consuming and requires technical knowledge. For non-technical users or those handling a large number of EML files, the DRS Softech EML Converter Tool is a faster and more secure solution.
