Import/Export WLM Emails to Office 365 with Attachments

Would you like to import your EML files into your Office 365 account and access them conveniently through the Outlook Web App? You’re in the right place! This guide will walk you through migrating EML data to Office 365, enabling seamless access to your emails in the cloud.

Let's understand the EML file format first before delving into specifics.

What are EML Files?

Individual email messages are kept in the E-Mail Message File, or EML, file type. The sender, recipient, subject line, body text, attachments, and formatting all have elements of an email.

Importing EML File into Office 365

Importing EML files into Office 365 (Exchange Online) or accessing them via the Outlook Web App doesn’t have a direct built-in method. However, there are two effective approaches to achieve this:

Method 1: Outlook Desktop Client

This approach will do the EML for Exchange Online mailbox migration using the Outlook desktop Application. Let's start.

1. Download And Set Up The Outlook Desktop Client

If you do not already have it, download and install the Outlook desktop client fit for your running system.

2. Drag & Drop EML Files into the Relevant Outlook Folder

Launch the Outlook desktop version. Go to the folder in your inbox (Inbox, Sent Items, etc.) where you wish to import your EML files. Then find your EML files on your computer and just drag and drop them into the Outlook program's intended folder.

3. Export a PST File from the Outlook Desktop Application

Export the mailbox into PST once your EML files are on your Outlook desktop. You must apply the Outlook Native Import/Export Wizard. See "File > Open & Export" > "Import/Export". After "Export to a file", select "Outlook Data File (.pst)", then the folder from which you imported EML data earlier. Select the save location and finish the exporting procedure.

4. Import a PST File into Office 365 Exchange Online

Use the Microsoft Network Upload approach to import PST to Office 365 (Exchange Online) following these guidelines:

• Make sure every PST file is ready and easily available.
• Get and run the Azure AzCopy utility from the Microsoft website.
• Upload the PST files to the Azure storage location that Microsoft has supplied using the AzCopy tool.
• Make a CSV file matching the PST files to the suitable mailboxes.
• Go to Data Governance in the Office 365 Security & Compliance Center; import and create a new import task.
• Make sure the PST files and mapping match.
• Finish the configuration and launch the import procedure.
• Verify the development and make sure every piece of data is imported accurately.

This method is both time-intensive and complex, often discouraged even by experienced users.
