MSG → EML

ConvertX's MSG to EML converter allows you to easily transform Outlook-specific email files into a widely compatible format. This is essential for users needing to access or archive emails outside of Microsoft Outlook.

MSG files are proprietary Microsoft Outlook message files, encapsulating an email with its metadata and attachments in an Outlook-specific structure. EML, conversely, is a standard plain-text format used by many email clients, storing a single email according to internet message standards. Converting MSG to EML involves extracting the email's headers, body content (plain text and HTML), and any attachments from the MSG container and reconstructing them into a standard EML file, making the email accessible across various platforms and applications.

The conversion from MSG to EML typically preserves the full integrity of the email's content, including text, HTML formatting, and all attachments. You can expect a high-fidelity transfer of your email data.

Tips

Verify attachments: After conversion, open the EML file to ensure all attachments are correctly embedded and accessible.
Batch convert for efficiency: If you have multiple MSG files, use our tool's batch processing feature to save time.
Check for encoding issues: For emails with non-standard characters, quickly review the converted EML to confirm proper character encoding.
Keep original MSG: Always retain your original MSG files until you've confirmed the successful conversion and integrity of the EML output.

Common use cases

Migrating emails from Outlook to a different email client like Thunderbird or Apple Mail that supports EML.
Sharing individual email messages with colleagues or clients who do not use Microsoft Outlook.
Archiving specific emails in a universally readable format for long-term storage or compliance purposes.
Accessing an email's content on operating systems where Outlook is not installed or available.
