How to Import EML Files into Outlook (New, Classic & Web)?

Quick Answer: You can import EML files into Outlook using New Outlook’s built-in import feature. Go to Settings > Files > Import, select the folder containing your EML files, choose the destination account and folder, and start the import. For Classic Outlook, you may need an alternative workflow, such as importing through a compatible email client or converting EML files to PST.

Can Outlook Import EML Files Directly?

Yes. Microsoft has added bulk EML import support to New Outlook for Windows, so you don’t have to necessarily use a third-party converter to move saved email messages. You can choose a folder of EML files and import them into a folder in your Outlook account.

But the way is different on which Outlook you use. New Outlook includes a built-in EML import option, while Classic Outlook does not have the same native bulk-import workflow for EML files. Microsoft also limits the import function built into the New Outlook to EML files up to 14 MB each and only imports files in the folder you select, not EML files in its subfolders.

If you have hundreds EML files in multiple folders, need PST archive, or cannot use New Outlook, choose a method that matches your requirements.

Few Things You Need to Know Before Importing EML Files

Please check the following before starting an EML to Outlook transfer:

  • First of all check which Outlook you are using, whether it is New Outlook, Classic Outlook, or Outlook on the Web.
  • Make a backup of your original EML files.
  • If you have multiple .eml files then collect them into manageable folders.
  • If you want to use the built-in import in New Outlook, check the size of larger EML files.
  • Select whether you want individual emails or a complete folder based migration.
  • Make sure to check the attachments after completion of migration. Check them after import.

Important: Do not delete the original EML files until you verify that the imported emails and attachments are available in Outlook.

Method 1: Import EML Files into New Outlook for Free

If you’re working with a comparatively small number of EML files and you’re using Classic Outlook for Windows, the old manual method is handy.

Step 1: Make a folder in Classic Outlook

Open Classic Outlook and create a new folder to place the imported EML messages.

By way of example: New Folder >> Inbox >> Imported EML

Step 2: Find your EML files

Launch File Explorer and navigate to the folder that contains your .eml files.

Select the EML messages that you want to import.

Step 3: Move EML files to Outlook folder by drag and drop

Drag and drop the selected EML files from File Explorer into the Outlook folder you created.

Important: Do not drag EML files to the wrong place

One common problem is that EML files are dragged directly into the Inbox or elsewhere – Outlook handles them differently.

Create a new folder in Outlook for a cleaner manual import, and place the EML messages in that folder.

When should you use this method?

  • No additional migration software is required.
  • For a small number of EML files.
  • Easy for users familiar with Classic Outlook.
  • Good when you just want to move a couple of messages.

Method 2: Open an Individual EML File in Outlook

The new Outlook for Windows has a built-in option for bulk import of EML files. This is an important difference to older Outlook documentation which states that EML files cannot be imported directly.

Current instructions from Microsoft are:

Settings >> Files >> Import >> Start import.

Steps to import EML to New Outlook

  1. Open New Outlook for Windows
  2. Go to Settings.
  3. Navigate to Files.
  4. Choose Import.
  5. Click on Import start
  6. Browse to the folder where your .eml files are stored.
  7. Choose the destination account and folder.
  8. Choose Import.

Microsoft says it only imports the top-level EML files in the selected folder. And it ignores EML files stored in subfolders. All EML files must be within the documented size limit of 14 MB as well.

When to use the built-in import in New Outlook

When is this a good option?

  • You’re on the new Outlook for Windows.
  • You have EML files with small size.
  • Your EML files will be saved directly in the folder you select.
  • You are not required to import nested subfolders by default.

If you have a large EML collection beyond supported limits or a complex folder hierarchy, look for another method.

Method 3: Import EML Files into Outlook Web

1. Go to the location where you have stored your EML files.

2. Right-click the EML file you want to import into Outlook.

open EML Files

3. Now, choose the Open With option in the Explorer menu and select Outlook to open EML files.

Done!! This is how you can manually transfer EML files into Outlook.

However, dealing with manual methods is ineffective with a large number of EML files. It has numerous disadvantages, including:

  • Users have to go through numerous steps as you can only import a single EML file at a time.
  • When you need to import a large number of EML files to Outlook, the manual method is not feasible.

Method 4: Transfer EML Files to Classic Outlook Using a Converter

The manual method mentioned above is only suitable for importing a few emails, not for bulk EML files. It’s not recommended for this task. Instead, we recommend using trusted third-party software to avoid any data loss. Advik EML Converter is a reliable tool to import multiple EML files into Outlook format. It can easily convert EML to PST which you can use to import to Outlook. Users can easily migrate unlimited EML files to Outlook PST file using this converter.
