MSG File

File extension .MSG
CategoryDocument File
DescriptionMSG file is a MS Outlook email saved to a separate file. Such mail format is also used in The Bat!, Windows Mail, MDaemon, etc. It contains email fields and attachments, supporting both plain text and HTML mail formatting. As a rule, the mail content is encoded by base64 scheme. Encoding is required for mail to pass the mail servers that originally process text only. MSG can be opened in the program version it was created in, and the file will conflict with all other applications. To convert .MSG to PDF, HTML, TXT or other formats use the online converter.

Convert MSG to EML — Frequently Asked Questions

What is the difference between MSG and EML?
MSG is Microsoft Outlook's proprietary binary format for storing a single message. EML is the open RFC 2822 plain-text format used by Thunderbird, Apple Mail, and most other clients. Converting MSG to EML makes messages accessible outside the Outlook ecosystem.

Will my email attachments be preserved when converting MSG to EML?
Yes. Attachments stored in the MSG file are re-encoded as base64 MIME parts in the EML output, which is how other email clients expect to find them. The attachment names and types are preserved.

Can I import the resulting EML file directly into Thunderbird?
Yes. Thunderbird accepts EML files via drag-and-drop into a folder. You can also use the ImportExportTools NG add-on for bulk imports of multiple EML files.

Does conversion work for MSG files with HTML-formatted bodies?
Yes. HTML-formatted message bodies are preserved in the EML output as a text/html MIME part. Plain-text bodies are preserved as text/plain parts.

Is there a risk that the converted EML will not display correctly in some clients?
EML is a well-defined standard, so compatibility issues are rare. Very old Outlook messages with custom rich text formatting may lose some RTF-specific styling, as EML does not support RTF as a MIME type.

Can I convert MSG files without having Microsoft Outlook installed?
Yes. This online converter processes MSG files server-side without any dependency on Outlook. The desktop tool Total Outlook Converter Pro also does not require Outlook to be installed.

How do I convert a large archive of MSG files to EML in one operation?
Total Outlook Converter Pro ($99.90) supports command-line batch processing: TotalOutlookConverterPro.exe C:\msg_folder C:\eml_output /ConvertTo eml /ProcessRecursively. It processes thousands of files without any manual steps.

How do I open an MSG file without Outlook?
Convert it to EML — every non-Outlook mail client (Thunderbird, Apple Mail, Windows Mail) and many text editors read EML directly. This avoids installing Outlook or a third-party MSG viewer just to read a message someone exported from their mailbox.

Can Outlook for Mac open MSG files?
Outlook for Mac has historically had poor .msg support — older versions cannot open Windows-created .msg files at all. Converting MSG to EML sidesteps the problem: Apple Mail and Outlook for Mac both read EML, so the message opens on macOS without extra tooling.

Does MSG to EML conversion preserve the date, sender, and recipients?
Yes. Headers — From, To, Cc, Date, Subject, Message-ID — are carried into the EML intact, so threading and sorting still work after import. Outlook-specific metadata with no MIME equivalent (read/unread state, follow-up flags, color categories) stays behind; it lives in the Outlook store, not in the message itself.

Can I search inside MSG files without opening each one?
Yes. Mail Terrier indexes the email files on your drive and searches their contents, so you do not have to open messages one by one to see what is in them. Mail Terrier searches MSG, PST and MBOX files by keyword, sender, or date range, combines terms with AND, OR, and NOT, and needs no Outlook installed.

What Is MSG?

MSG is Microsoft Outlook's proprietary binary format for storing a single email message, including its headers, body, attachments, and metadata. The format is documented by Microsoft but requires specific libraries or Outlook itself to read correctly. It is not natively supported by non-Microsoft email clients.

What Is EML?

EML is the plain-text format for individual email messages defined by RFC 2822. Thunderbird, Apple Mail, Windows Mail, and dozens of other clients use EML natively. The format is human-readable, open, and supported by virtually every email import tool. Attachments are base64-encoded within the file.
