How to Open .MSG Files: Step-by-Step Outlook Access

I got my first .msg file from a client in 2010 and stared at it like it was written in hieroglyphics. That file contained a contract I needed to sign, and I had no idea how to access it.

The solution turned out to be simpler than expected. Outlook handles these natively, but there are free alternatives that work just as well on any platform. I’ve since opened hundreds of these files across Windows, Mac, and even Linux.

You’ll get full access to the email content, attachments, and metadata without needing a Microsoft 365 subscription. The process takes under 2 minutes once you know which tool to use.

Works for single files or batches, and I’ll walk you through every option.

What Youll Need

Instructions

Here’s the procedure I follow to access these files without any compatibility issues.

If you have Microsoft Outlook installed, this is the simplest approach. Double-click the .msg file and it will open directly in Outlook, preserving all formatting, attachments, and metadata. This method works seamlessly with Outlook 2013 or later.

Watch for the file to open in a new window with the original email layout intact. If it doesn’t open, right-click the file, select Open with, and choose Outlook from the list of applications. This ensures the system associates the file type correctly.

If you don’t have Outlook installed, use the Outlook Web App. Log in to your Microsoft account through a browser, navigate to Outlook, and drag the .msg file into the compose window. The email will render as if it were sent to you.

Alternatively, upload the file to OneDrive or SharePoint, then open it directly from the web interface. This method works well for Office 365 users and doesn’t require local software installation.

For those without Outlook access, third-party tools like MSG Viewer or LibreOffice can open these files. Download and install a trusted viewer, then launch it and use the File > Open menu to locate your .msg file.

Verify the tool supports attachments and embedded images. Some free viewers have limitations, so check reviews or documentation before committing. I’ve found MSG Viewer by Encryptomatic particularly reliable for preserving all email elements.

To share the email with non-Outlook users, convert it to a universal format. In Outlook, open the .msg file, click File > Save As, and choose HTML or PDF as the format. This creates a file anyone can open with a standard browser or reader.

For batch conversions, use a tool like MSG to PDF Converter. Select the files or folder, choose the output format, and run the conversion. Confirm the output files open correctly in your preferred viewer before deleting the originals.

Tips and Common Mistakes

These practical insights will save you time and frustration when working with this file type.

File Association Fix: If double-clicking doesn’t work in Step 1, you’ll need to manually set the file association. Right-click any .msg file, select Properties, then Change, and choose Outlook as the default program. I learned this the hard way after my first three attempts failed to open properly.

Browser Compatibility Note: For Step 2, ensure you’re using a modern browser like Chrome, Edge, or Firefox. Older browsers might not support the drag-and-drop functionality needed to open the file in Outlook Web App. This is particularly important for Office 365 users.

Viewer Verification: When trying third-party tools in Step 3, always test with a non-critical file first. Some free MSG Viewers only display text, stripping out attachments and formatting. I’ve found the Encryptomatic version handles everything, but it’s worth confirming before committing to any tool.

Conversion Quality Check: In Step 4, after converting to PDF or HTML, open the new file to verify all elements transferred correctly. I once converted a batch of files only to discover all images were missing—the originals were my only backup.
