Microsoft Outlook stores your emails as MSG and PST. What is the .msg file? How to open the .msg file on Windows and Mac? If you are looking for the answers to the above questions, you can continue to read this post.

If you see a .msg file, you’re probably using Microsoft Outlook because Outlook uses MSG files to export email and perform other tasks.

What Is .msg File?

Microsoft’s email client, Outlook, uses the MSG format (files with a “.msg” extension) to store individual email messages. When you drag and drop an email from Outlook to a folder on your computer, it’s converted to an MSG file.

This file stores the email text, but it also stores email information such as who sent the email, who received it, and when. It also stores links and attachments in emails.

MSG files are harmless when created within Outlook itself. There is no risk in opening MSG files that you create yourself, but you should be wary of opening files from sources you don’t trust. This is especially true for exported emails that contain attachments. Since you can’t judge the attachment without opening the MSG file, you could be putting your PC at risk.


Tip: You can export or backup contacts, email messages, calendar, and task data from your email account to an MSG file. Besides, Outlook MSG backup can help you transfer MSG files to another PC or a new version of this email client. To do that, you can try the professional backup tool – MiniTool ShadowMaker.

How to Open the .msg File on Mac?

Like Windows, macOS supports the full Microsoft Outlook client, available as a standalone app or as part of the Office suite. Unfortunately, the Mac version of Outlook doesn’t allow you to open or export MSG files.

To open MSG files on Mac, you’ll need to install a third-party MSG viewer from the App Store. To start, download and install the MSG Viewer for Outlook app from the App Store. Once installed, launch the app from the Launchpad.

Then, you can select the client or address book app you want to open in the Opening Files section. If you want to quickly view the file, select Quick View, or select one of the conversion options (eg. Convert to PDF) to convert the file to another format. Once your settings are in place, select File > Open from the menu bar.

In the Finder window, find and select your MSG file, then select the Open button. This will begin the conversion process from MSG to the open-source EML format.
