How to open .msg/.eml files without emailStartSession

Hi All


I have a whole bunch of .msg (email) files in a directory and
would like to import such into HF, any clues like to call some API functions instead.

Thanks in advance.

This is what I'm looking for too... is it possible in WebDev?

Anything is possible with time and money

File parser is always possible just depends as to whether this is a one off import or you have something more in mind.

.msg files are usually Microsoft Outlook Item format a Compound File Format, but not always. There are a number of mail servers and clients that name files as .msg even though they are really rfc2822 text.

Thanks... the ones I'm interested in viewing... (ideally without opening Outlook), are Outlook .msg files. Does anyone know if there's a function within WebDev that will do this?

Outlook msg files can't be used direcly without heavy programming in windev/webdev as you can see in the remark of the EmailImportSource.

If you have outlook installed it's easy, just import you msg files to one outlook folder and use the functions to access the outlook data.

You have to use some external tool (google is your friend) to convert from msg to eml, pdf or some other open format.

Thanks... the EmailImportSource looks like it would do it, except it doesn't support .msg

It will be nice in future pcSoft can have a new viewer function for .ost/.msg/.pst like below links:

Just a thought and a wishlist.

Nice information

The process of converting multiple MSGs to EML format can be done commercially using advanced software such as Softaken MSG to EML Converter. This software stands as a reliable solution for bulk export in EML format. This software is one of the best-chosen methods to transfer data from MSG files to EML format on any Windows system. So get this reliable MSG to EML export software to do the right job.

I use msgreader.dll within windev or webdev

If you want to open .msg or .eml files without using emailStartSession or relying on Outlook, BetaVare Export MSG to EML Software is a simple and effective tool. I used it when I had a bunch of MSG files that needed to be accessed on a system without any email client installed and the tool worked perfectly. It converts MSG files into standard EML format which can be opened in many email programs like Thunderbird or even viewed in plain text. The software supports batch conversion keeps the original formatting and attachments and works smoothly on all Windows systems. It’s easy to use and doesn’t require any technical setup making it a practical solution for accessing MSG or EML files without emailStartSession.

If you'd like to open MSG or EML files without having to emailStartSession, then the easiest thing to do is open them with a standalone viewer or conversion tool. You don't need to have Outlook open or use emailStartSession to read either of the formats. There are several lightweight viewers that minimally will open and view MSG/EML file formats instantly without any configuration. You select the file and view the email body, all the headers, and the attachments. If you want to convert the file to another supported readable format and retain permanent access to that format, DailySoft MSG Converter is a viable option as well. The trial version allows you to explore the features while the technical support team is available to assist if you run into any issues with the conversion.
