MSG Files

There are numerous diverse file varieties RAR, ICA, BKUP,ICS, etc. These formats are divided into groups such as music or text files, each carrying out particular functions within their own limitations. For instance, an SRT file could be optimal for video captioning, yet a VTT file is considered to surpass it. However, one file format that stands unchallenged is the .MSG file format.

Encountering an .MSG file likely signifies the use of Microsoft Outlook, as this software uses these files to export emails and undertake other assignments. If one lacks Outlook on a Windows system or uses a Mac’s Outlook version, accessibility to such files might be restricted. To open MSG files on either Windows or Mac, a particular course of action needs to be pursued. We will get into the details of everything thing in this

What is a .msg File?

MSG File

A file with the .msg file extension is usually connected to Outlook Mail. It’s like a special envelope for emails, appointments, contacts, or tasks.

When it’s an email, the MSG file can keep important details like when it was sent, who sent it, who received it, what it’s about, and what’s written inside (with special styles and links). But sometimes, it’s just info about a contact, an appointment, or a task.

These files started being used with Microsoft Office 2003. Even though newer Office versions came out, MSG files are still important for Outlook.

It is now the usual thing for everyone using Outlook, especially when emails are sent as attachments or saved on a computer. Since it started, Microsoft has made more than 10 different versions of the .MSG file. Before Outlook 2003, this email program used .PST (or Personal Store) to save stuff. 

Note: If your MSG file isn’t about Outlook, it might be something for the Fallout 1 and 2 games. These games use MSG files to hold messages and talk about characters.

Usage of MSG Files

MSG files have various uses within Microsoft Outlook. They help you share different types of information between users.

  • For emails, they contain all the email details like the date, sender, recipient, subject, message, and any attachments. This is useful for sharing multiple aspects of an email at once.
  • When it comes to appointments and meetings, they carry all the important info such as the time, location, and even the message if needed.
  • For contacts, they are used to share contact details like the person’s full name, email address, and phone number.
  • If you’re dealing with tasks, this file can hold task information like dates, the task’s message, and its priority level.
  • These documents can be looked into to get details about the sender, receiver, subject, content, attachments, and other info. This can be useful for marketing, research, or making sure rules are followed.
  • If an email is accidentally deleted or something goes wrong, you might be able to get it back from a .msg file.

Pros and Cons of an MSG File

MSG files are an excellent file format for storing emails. However, it’s important to consider their merits and limitations. Let’s take a look into the pros and cons of .msg files.

PROS

  • Multiple Uses: .MSG files are really handy. They can be used to share meeting locations or to send PDFs through email. You can use them to update, inform, and invite people with just a simple click.
  • Small File Size: When compared to other file types like .EML, these files are quite small. If you get lots of emails each day, big files can quickly take up all your computer space. But with MSG, you don’t have to worry about running out of room.

CONS

  • Doesn’t work on old versions of Microsoft Outlook: Even though not many people use versions of Outlook before 2003, those versions can’t open such files. So, if you’re trying to talk to someone using an older Outlook, you might need to find another way to plan meetings or share stuff.
  • Only works with Outlook: Just like they are not working with older Outlook versions, they also don’t work with other programs. Sometimes, they have special Outlook stuff in them that can’t be seen anywhere else. This is different from file types like .EML, which can be opened by almost any email program.

How to Open a .msg File?

One can open MSG files with or without Outlook. Let’s see the detailed steps for each method.

How to Open MSG Files on Windows?

This file format is used by Outlook. To open it on a Windows computer, you usually need the Outlook desktop app.

  • If you have Outlook set up on your computer, then the files should open with it. To open an MSG file, just double-click it on your desktop or in File Explorer. If MSG files don’t open with Outlook automatically, you can right-click the file and choose “Open With”

  • You can also put them into your Outlook inbox manually. Right-click the file on your desktop or in File Explorer, then select “Copy“.
  • With your Outlook inbox open, press Ctrl + V to paste the file into it. This will let you see the message in your mailbox.

Now If you don’t have Outlook installed, you can use a different program like FreeViewer MSG Viewer. It might look a bit old-fashioned, but it can help you see what’s inside these files on Windows.

  • In the app’s window, choose the folders with your MSG files on the left. The files will appear on the right.
  • To look inside a file, just pick it from the list in FreeViewer MSG Viewer. You’ll then see everything in the file, like any extra stuff attached to it and any hidden information at the bottom.

  • Keep in mind, though, that you should only use this for files that aren’t private. Uploading private files to an unknown website could share your personal info, including your email and other messages.

How to Open MSG Files on Mac?

Just like Windows, macOS also works with Microsoft Outlook. You can get this program by itself or as part of the Office package. However, the version of Outlook for Mac doesn’t let you open or move MSG files.

To deal with MSG files on a Mac computer, you’ll have to use an additional tool from the App Store or consider an online service. There are different applications available, but one of the simplest to use is the MSG Viewer for Outlook. This tool works by changing the files into the open-source EML format.

  • To start, download and install the MSG Viewer for Outlook app from the App Store. After it’s installed, open the app from the Launchpad.

  • With the MSG Viewer for Outlook app running, you can pick the email client or address book app you want to use in the “Opening Files” part.
  • If you only want to take a fast peek at the document, click on “Quick View“. Otherwise, you have different choices to change the file, such as making it into a PDF format. When you’ve decided what you want, tap on “File” in the top menu, and then pick “Open“.
    Choose Quick View
  • In the Finder window, locate and choose your MSG file, and then click “Open“. This will start the conversion process from MSG to the open-source EML format.
  • The MSG Viewer for Outlook app will manage the conversion. When it’s done, the email app you selected earlier will open automatically, allowing you to view the file.

How to Create an MSG file?

Making an .MSG file is easy. Just take something from Microsoft Outlook and put it into a folder or onto your desktop. Outlook will then change the email, task, appointment, or contact into an MSG file where you put it. 

The name of the file will come from what you wrote in the subject, but you can change it if you want. You can also save what you picked in Outlook. Go to ‘File’, then ‘Save As’, and pick where you want to put the file.

How to Convert an MSG File to Other Formats?

Microsoft Outlook has a neat trick up its sleeve, it can change MSG files into different types of formats, depending on the kind of file you have. Like, if you have a message, you can switch the MSG file into TXT, HTML, OFT, or MHT. For tasks, you can turn them into text stuff like RTF. Contacts can become VCF, and calendar events can change into ICS or VCS.

Once you’ve got your file open in Outlook, go to the File menu, then pick Save As. Look for the Save as type option and choose the format you want from the list.

You’ve got another option, too. There’s a program called Filestar that can change MSG files into different types. It works on Windows and macOS computers. 

If you’re into online solutions, there’s Zamzar. It can help you turn your file into PDF, EML, PST, or DOC. This tool runs in your web browser, so it’s cool with any operating system you’re using.

For Linux users, there’s a tool called MSGConvert. It’s a bit technical as you use it from the command line, but it can change MSG into EML files.

You can also change it into contacts files. First, switch the MSG file to CSV. Then, bring those contacts into Outlook by dragging the .MSG files to the My Contacts section. From there, go to File, then Open & Export, and find Import/Export. You can also decide where to save the new CSV file.

Now, if you’re ever thinking of changing a Fallout Game Message file into something else, it’s not very likely you’ll find it helpful. But if you’re feeling experimental, you can try opening the MSG file with a text editor and saving it as a new one.
