How to Open MSG File without Outlook? Tested Solution
Overview: If you have received a MSG file, but don’t have Outlook installed and subscribed, don’t worry, you are not alone. This is an issue users struggle with daily. In this informative guide, we will be learning to open MSG file without Outlook on both Windows and Mac OS.
Trying to open MSG without Outlook is the most common issue faced by users, as .msg is an Outlook-based file format that stores Outlook items like emails, calendars, contacts, etc.
It is easy to access MSGs from Windows, but when it comes to Mac, email clients like Gmail, Webmail, etc., the process becomes nearly impossible, as MSG is a proprietary format of Outlook and Windows.
Not everyone uses Outlook or has it subscribed. Some users simply do not have Outlook installed, some want to shift to another email platform, or some want to open old msg files without Outlook. Users look forward to open MSG files without Outlook and converting them to a format that is universally accessible.
Common Errors While Opening MSG Without Outlook
- Files cannot be opened due to an error or the file size.
- “Windows can’t open this file” error is mostly shown when you don’t have Outlook installed, and double clicks the MSG to view.
- “The file is corrupted or cannot be opened” error is shown when files get damaged during the process or contain complex HTML.
- Displays the MSG in Winmail.dat format when the original formatting gets disturbed. It automatically changes into Winmai.dat format, which most of the email clients can’t decode.
Can I open msg files without Outlook? Quick Answer
Yes, you can save MSG files without Outlook by using manual ways like renaming MSG files into .txt, .html, .eml, dragging & dropping them into text editors, or using the online MSG file viewers.
Instead of using the online viewer, you can use the free offline MSG viewer, which allows you to view and open msg file without Outlook on Windows OS, without any limitations, errors, or disturbance in the original data structure. The permanent solution to this is to directly convert MSG into a universal format. You can use the free MSG file viewer by RecoveryTools, which works without internet, allows you to open and view MSG in bulk, and keeps data secure & safe.
Manual Ways to Open msg file without Outlook Account
We will see multiple manual ways to view and open MSG files without Outlook. Here are the brief steps:
#1 Convert MSG to EML, HTML, or TXT
- Right-click on the MSG file.
- Rename the .msg file extension to .eml. .html, or .txt to open and view.
- EML will be opened in Thunderbird, TXT in Notepad, and HTML in any browser.
Note: This method is not actually importing; you can just open and view the MSG without Outlook using these renaming approaches. It is not advisable, especially for professionals, as it results in broken formatting, missing attachments, metadata, and other important data elements
#2 Drag & Drop into Text Editors
- Open both the local file explorer and any text editor like Notepad++, Hex editor, Sublime Text, etc. on one side.
- One by one, drag & drop your MSG files into the text editor.
Note: This way is only suitable for developers as it only shows the binary structure of the MSG file and not the actual visual with attachments, fonts, etc.
#3 Using SeaMonkey for Mac Users
Apart from Outlook, SeaMonkey is another way to access old .msg files, and the Mozilla company created it.
- Install SeaMonkey on a Mac machine.
- Choose Window >> Mail & Newsgroups from the Menu.
- Press the Cancel when asked to set up a new account >> Exit icon.
- Choose File tab >> Open File option.
- Select the needed MSG and open it here.
Drawbacks of Saving MSG files without Outlook Manually
- The manual way is a risky approach as renaming and dragging & dropping the MSG files results in data loss, damaged files, and format loss.
- Especially, the online file viewers are risky as they work with the internet, which may lead to data corruption and data breaches.
- It does not support opening MSG in bulk. You will have to open each file one by one and view it.
- You cannot view the metadata and properties, which are very important for IT admins, lawyers, investigators, and enterprises.
- The manual approach does not open damaged, corrupted, and password-protected MSG files.
