What are EML Files?

EML files are like containers that hold single email messages. They include everything in the email, like who sent it, who it was sent to, the subject, the body, any attachments, and how it’s formatted. 

How to Import EML Files to Office 365

Since Office 365 doesn’t have a built-in way to import EML files, you’ll need to use a different method:

Method 1: Use Outlook Desktop Client (Best for Migrating a Small Number of EML Files)

For this method to import EML to Office 365, you’ll use the Outlook desktop app to move EML files to your Exchange Online mailbox. 

Step 1: Get the Outlook Desktop Client — If you don’t have the Outlook desktop client, download and install a version that’s compatible with your computer’s operating system.

Step 2: Importing EML Files to Outlook — Open Outlook and find the mailbox folder where you want to add your EML files (e.g., Inbox). Drag your EML files from your computer and drop them into the chosen folder in Outlook. 

Step 3: Exporting Mailbox to PST File — To export your mailbox as a PST file, use Outlook’s Import/Export Wizard. Go to “File” > “Open & Export” > “Import/Export.” Select “Export to a file” and choose “Outlook Data File (.pst).” Select the folder where the imported EML files are located.

Step 4: Adding PST Files to Office 365 Exchange Online — To import PST files into Office 365 Exchange Online through the Microsoft Network Upload method: 

  1. Prepare PST Files: Ensure PST files are accessible. 
  2. Install AzCopy: Download and install the Azure AzCopy tool. 
  3. Upload to Azure: Use AzCopy to upload PST files to the Microsoft Azure storage location. 
  4. Create CSV File: Map PST files to specific mailboxes in a CSV file. 
  5. Start Import Job: Navigate to the Office 365 Security & Compliance Center and create a new import job under Data Governance > Import. 
  6. Verify and Start: Verify PST files and mappings, then initiate the import process. 
  7. Monitor Progress: Check the progress and confirm that all data is imported successfully. 

Method 2: Drag & Drop Method – Migrate EML to Microsoft 365

Assuming you have all of the EML files on your hard drive,

  1. Open Microsoft Outlook.
  2. Create a new folder by right-clicking on the left panel.
  3. EML files are what you should call them.
  4. While Outlook is operating, open the folder holding your EML files on your computer.
  5. Choose all of the EML files.
  6. Drag and drop all of the EML files into the newly created Outlook folder (do it for 50 files at a time if you are having an issue).

EML emails will appear in Outlook once this is completed.

In certain circumstances, the imported emails’ body text is not shown in the Outlook interface. It means that this strategy isn’t right for you to import EML to Office 365.
