8 Ways To Open Outlook MSG Files On Mac

If you need to open an Outlook email or attachment in MSG format, there are various ways to do so.

The frustrating thing about the Windows version Microsoft Outlook is that it generates MSG files that can’t even be opened by Outlook on Mac.

The good news is that this annoying situation can be solved easily thanks to several different solutions.

Here then are the best ways to open Outlook MSG messages on a Mac.

1. MSG Viewer for Outlook

MSG Viewer is a simple but effective app which can instantly open Outlook messages on a Mac. MSG Viewer for Outlook supports batch processing of files and conversion of Outlook MSG contacts in VCF format.

Once installed, MSG Viewer opens your emails in a basic Outlook style interface which feels like using Microsoft Outlook on your Mac.

The free version only converts selected parts of MSG files – you need to upgrade to the full version for $18.99 to get full conversion of messages and batch processing.

You can download MSG Viewer for Outlook on Mac either directly from the developer or from the Mac App Store.

2. .msg Viewer (Free)

.msg viewer is a free online app that allows you to simply drag and drop .msg files into it and view them in a browser on any Mac.

Note that the conversion is done in the Cloud so if the Outlook file you’re trying to open is confidential, you may be better using another method.

To use it, simply go to .msg viewer and click on “Select .msg file” to upload and read it.

3. Outlook.com (Free)

Another solution is to simply email the file as an attachment to an Outlook.com email address (formerly Hotmail and Windows Live Mail).

Outlook has a built-in MSG viewer that you can then read the .msg file with.

4. MailRaider

MailRaider can extract the text out of any MSG file although like MSGConvert, it removes the formatting from the original Outlook message.

Note that MailRaider won’t actually save email in MSG format as it’s only an MSG reader, not an editor.

You open MailRaider simply by double-clicking on the app icon, go to File -> Open and then browse to the .msg file you want to open.

Alternatively, you can double click on any .msg file on your Mac and MailRaider will open automatically as the default application for MSG files.

MailRaider is available in a standard and Pro version. The Pro version offers several advantages such ability to export to Contacts, calendar and PDF.

You can download MailRaider from the Mac App Store or directly from the developer.

5. MessageViewer Online (Free)

MessageViewer Online is an online Outlook viewer that lets you view e-mail messages in EML, MSG and winmail.dat (TNEF) formats.

It can also open email file attachments but uploads are limited to 8MB.

Note also that it’s not the msot secure way to open Outlook files as you have to upload mails to the cloud.

6. MsgViewer (Free)

MsgViewer is an email-viewer utility for .msg e-mail messages and is based on Java so it works on Windows/Linux and Mac platforms.

MsgViewer uses a Java API to read mail MSG files programmatically.

MsgViewer can also extract an embedded PDF from a MSG file.

However, we don’t recommend installing Java on Mac for various reasons so only use MsgViewer if you really have no other choice.

7. Change The File Extension (Free)

If the file you need to open was not directly created by Outlook, you may be able to simply change the file extension from .MSG to .EML which will enable Apple Mail to open it.

Alternatively, you can try changing the file extension to TXT and open the email in TextEdit on your Mac.

This also works if you right-click or CTRL-click on the file, select Open With… and select TextEdit.

However, in our experience this rarely works anymore.

8. Install Windows on your Mac

This is the most complicated and time-consuming way to open Outlook files on your Mac but may be worth it if you use a lot of Windows only applications.

Nowadays there are several ways to run Windows on a Mac but the easiest is by using a virtual machine such as Parallels.

This enables you to run macOS and Windows simultaneously so that you can switch between both at any time.
