Need to convert bulk MSG files to EML with attachments

[ryanturner]

I have a large folder of Outlook MSG files that were saved from different email conversations over time. Many of these emails include important attachments like PDF files, Word documents, Excel sheets, images, and some other work-related files. Now I need to move these MSG emails into an email client that supports EML format, but doing this one by one is taking too much time.
The main problem is that MSG files are not easy to open in every email client. They usually work with Microsoft Outlook, but I need these emails in EML format so they can be opened in clients like Thunderbird, Windows Live Mail, Apple Mail, or other EML-supported applications. I tried checking a few files manually, but when there are hundreds or thousands of MSG files, manual conversion is not practical.
My biggest concern is attachments. I do not want the emails to convert without the attached files. Each email should keep its original attachment with the message. Sender details, receiver details, CC, BCC, subject line, date, time, message body, formatting, and attachments should stay properly connected after conversion. Some emails also have long message threads, so I want the email content to remain readable and not broken.
I am also worried about folder handling. The MSG files are stored in different folders according to clients, projects, and dates. If I convert them in bulk, I do not want everything mixed up in one place. It would be better if the output EML files remain easy to identify and manage after conversion.
Opening each MSG file in Outlook and saving it manually as another format is slow and not suitable for a large mailbox backup. Also, not every system has Outlook installed, so I am looking for a cleaner way to convert bulk MSG files to EML with attachments without depending too much on manual work.
What is the best method to convert multiple MSG files into EML format while keeping attachments and email details safe? Is there any safe process or tool that can handle bulk MSG to EML conversion without changing the original files?

When dealing with the conversion of MSG format emails to EML format with attachments, what is important is that no individual email should be touched manually. While MSG is an extension commonly used for Outlook, EML format can easily be accessed using software applications such as Thunderbird, Windows Live Mail, and others. In case of attachments, the job only gets more difficult as one needs all the pieces to be complete for it.


In case you want to go for the free option, you might use the program called Outlook provided that it is installed on your PC. The first step is to open your MSG file through Outlook. Then you will need to use Save As option and select a suitable email file type. Finally, transfer your file to the email client which supports EML. Of course, this approach is acceptable if you only need to convert a few MSG files.

But for bulk MSG files, this free method is not very practical. Opening hundreds of emails one by one takes time. It is also easy to miss some attachments or save files in the wrong folder. If the MSG files are from old backups, mixed folders, or different users, manual work can become messy very fast.

A better way is to first organize the MSG files before conversion. Put them in one folder, remove unwanted files, and make a backup copy. Then convert them in batches instead of doing everything randomly. After conversion, open a few EML files in Thunderbird or another EML-supported client and check the attachments, subject line, sender, and date.

It can be said that ToolsBaer MSG to EML Conversion Tool will come in handy here. This tool will prove helpful where there is a requirement for converting many MSG files into EML files and there is no need to do so repetitively. This tool offers batch MSG to EML conversion, preview of MSG files prior to export, possibility of deleting unneeded files selected by mistake, and selection of the output destination folder.

All I would recommend is for you to follow this easy guide: Do not use all the files at once. First try using only 10 or 15 files. Check out if the emails have attachments, To, CC, BCC, etc. Once you find that everything is ok, use the rest of your files.

So yes, bulk MSG to EML conversion with attachments is possible. This method will only work on small numbers. For large MSG collections, using a dedicated MSG to EML tool saves time and reduces small mistakes. Always keep the original MSG files safe until the converted EML files are checked properly.
