What is a MSG file?
An MSG file is a Microsoft Outlook message file that stores a single email, including the sender, recipients, subject, body, date, formatting, metadata, and any attachments.
MSG files are commonly created when users save or export individual Outlook emails for archiving, sharing, compliance review, or record keeping.
Because MSG is an Outlook message format, it can be difficult to open on devices that do not have Microsoft Outlook installed. FileViewerHub helps you inspect supported MSG files directly in your browser.
Powerful Client-Side MSG Tools
FileViewerHub processes your Outlook MSG files inside your browser for instant viewing, metadata inspection, and attachment saving without compromising your privacy.
Outlook License Not Required
Opening Microsoft's proprietary MSG email files typically requires a paid Microsoft Outlook subscription or a Windows environment. Our free viewer eliminates this barrier, allowing macOS, Linux, and mobile users to access and read saved Outlook files instantly within their browser.
Full Attachment Extraction
Outlook emails often house critical file attachments, images, and embedded objects. Our parser parses the underlying Compound File Binary format of the MSG file on your device, extracting attachments so you can download them with a single click.
Private & Sandboxed Previews
Protect yourself from malicious tracking pixels or active scripts embedded inside saved messages. Our client-side parser opens MSG structures in a secure browser sandbox, stripping executable elements while rendering rich text formats and metadata details.
What you can view inside a MSG file
Some MSG files may contain non-standard formatting, embedded objects, encrypted content, or unsupported attachment structures. FileViewerHub displays supported fields where they can be safely parsed in the browser.
Open MSG files without Outlook
You do not need Microsoft Outlook or Microsoft Office installed to open a supported MSG file. FileViewerHub works directly in a modern browser, which makes it useful on Windows, macOS, Linux, Chromebooks, and other devices.
This is helpful when someone sends you a saved Outlook message and you only need to inspect the email content, headers, or attachments without importing it into a mail client.
Open MSG files on Mac
MSG files are associated with Microsoft Outlook, so they can be difficult to open on macOS without Outlook. FileViewerHub helps Mac users inspect supported MSG files directly in the browser without converting or importing the email first.
You can select a .msg file, view the message details, and check attachments where supported.
What programs open MSG files?
MSG files are mainly used by Microsoft Outlook, but there are several ways to inspect them depending on your device and workflow.
Desktop email clients may be useful when you need full mailbox management. FileViewerHub is designed for quick viewing and inspection of supported MSG files without installing Outlook.
Convert or export a MSG file
Where supported, FileViewerHub can help you export the email message as a clean PDF document for easier sharing or record keeping.
If your file uses the standard .eml format instead, use the EML Viewer.
MSG vs EML: what’s the difference?
MSG and EML are both email file formats, but they are not the same.
An MSG file is a Microsoft Outlook message format that may include Outlook-specific metadata, formatting, and attachment structures.
An EML file is a more standard email message format used by many email clients, including Thunderbird, Apple Mail, Windows Mail, and Outlook.
If your file ends in .msg, use this MSG Viewer. If your file ends in .eml, use the EML Viewer instead.
Is it safe to open MSG files online?
MSG files can contain private messages, business records, links, tracking pixels, and attachments. FileViewerHub is designed to reduce privacy risk by processing supported MSG files locally in your browser for standard viewing.
Your MSG file is not uploaded to FileViewerHub servers to display the email. The message is read on your device and shown inside your browser.
Only open files from sources you trust. Be careful with links and attachments inside email files, especially if the sender is unknown.
