How can I convert Outlook MSG files to EML without installing Outlook?

[nick.smilth]

I have many old MSG email files saved from Outlook, but Outlook is no longer installed on my system. When I try to open these files directly, Windows does not show the full email content properly. I want to convert these MSG files into EML format so I can open them in Thunderbird, Windows Mail, or another email client. The main concern is keeping the email body, sender details, date, subject, and attachments safe during conversion. What is the right way to do this without using Outlook?

MSG files are not easy to open when Outlook is missing from the computer. Many people think about changing msg to eml will work, but that only changes the name, not the email format.
For one or two emails, you can use another PC where Outlook is already installed and save the emails manually. But for many old MSG files, that becomes slow.

A practical option here is GainTools MSG to EML Converter Software. It works on Windows and does not need Outlook to convert MSG emails into EML. This tool also keeps the email body, sender, date, subject and attachments readable after conversion.
Before using it on all files, try the free demo with a few MSG emails. That gives you a clear idea of how the final EML files will look.
