Our software has various inbuilt filters to convert specific .msg files to .eml based on different criteria as mentioned below:
Core Functionalities
Dual Mode to Add MSG Files
This MSG to EML conversion tool provides two different options to add and load Outlook MSG files in the software. Either you can choose the “select files” option to upload particular MSG files, or you can choose the “select folders” option to insert the whole MSG folders in one go without limitations.
Automatic Data Sync
When you select files/folders using the dual-mode, you just have to choose the main folder, and the software automatically syncs the entire MSG from the scattered data. It loads all the MSG sub-folders and files directly without selecting one by one.
Export MSG With All Items
This powerful MSG to EML converter can convert MSG to EML file with all the attributes and items in bulk. Whether it is a single file or multiple file the tool supports exporting MSG to EML with complete properties like email headers, inline text, fonts, links, subject, attachments, metadata, and other elements.
Data Security & Integrity
This is a reliable MSG to EML file converter that protects the data from getting lost or corrupted. It is a secure solution that converts MSG to EML format without any data loss, as it does not keep the data on the cloud or in its own environment. It is a fully desktop-based application.
Convert MSG to EML Quickly
You can export MSG to EML files in large batches without size limitations or errors. It can handle a large number of MSG folders/files and convert them in one go without consuming time & effort. Users can add unlimited .msg files and convert them collectively without any data loss.
Export ANSI & Unicode MSG to EML
This tool enables users to easily convert message files, both ANSI (created by Outlook 2002 and earlier) & UNICODE (default for Microsoft Outlook 2003 and later) type into EML. The software retains the complete properties after the conversion to EML from Unicode & non-Unicode MSG files.
Multiple File Naming Options
Convert MSG to EML with a unique file naming option to rename the resultant EML files with different patterns such as: Subject + Date (dd-mm-yyyy), From + Subject + Date (yyyy-mm-dd), From + Subject + Date (dd-mm-yyyy), Date (dd-mm-yyyy) + From + Subject, Date (yyyy-mm-dd hh: mm: ss) + From + Subject, etc.
Standalone & Offline Utility
This MSG to EML converter tool is independent and works without internet connectivity, making the software more secure to use. It requires no installation of any email client or platform to convert MSG to EML.
Preserves Folder Hierarchy
It keeps the original folder hierarchy and data structure intact. Without any changes, the tool displays and exports MSG files with proper folder hierarchy and structure.
Destination Path
The storage location selection option allows users to select their desired destination path for the resultant EML files. You can choose your required location for the converted EML files and directly export them in bulk.
User-Friendly Interface
It is an easy-to-use application that requires no technical knowledge or prior training to use. Any user with a technical or non-technical background can use this tool to convert MSG to EML files conveniently.
Compatibility
The software is compatible with all Microsoft Windows OS and macOS versions and servers. It supports all the previous and new editions of both Windows and Mac.
A successful MSG to EML conversion keeps all the important data. However, it leaves behind some Outlook-specific information that EML does not support.
Headers and metadata
All information associated with an email, such as sender, recipient, CC, BCC, subject, sent/received date, message ID, and internet headers, is retained. This information helps with keeping the original identification of the email intact.
Attachments and nested messages
Usually, all files attached to the email will remain as is after conversion. However, if the email contains a message within the message, it may or may not be retained, depending on the output format.
Formatting and hierarchy
HTML messages, fonts, pictures, hyperlinks, and signatures do not change for the email message. The folder where information is located is kept as it is so that emails do not arrive in a flat mass.
Size decreases while converting MSG to EML. Testing results, conducted by BitRecover, revealed that reduction occurred up to 45% when converting MSG to EML format because the compound container has a structure that a flat MIME file doesn’t require. In the case of an archive containing dozens of thousands of messages, it makes a difference between being written on a disk and not.
Outlook version 2002 and older produced ANSI .msg files. Whereas Outlook 2003 and later ones generated Unicode. Both load files without knowing which of them.
Outlook saves those too in .msg. The EML is email container, whereas contacts need to be saved in vCard or CSV and appointments in PDF based on the same tool using different saving options.
Some MAPI properties are exclusively used in Outlook without any equivalent corresponding to RFC 5322 so they cannot be put into plain text.
Here are a few examples of MAPI properties:
If there are any type of these formats involved in the given issue, then the PST format should be used as it handles everything without problems. You can convert MSG to PST, on the same licence.
These points are important to keep in mind because that is where many users make mistakes during their MSG processing. If the folder that is in front of you was exported out of the mailbox, the files should be processed in the .eml format. If the folder originated from the calendar or contact folder, the task should be done correctly without forcing the destination into email format.
Know why you should avoid using Web tools and switch to a secure offline tool:

FAQs
Yes, you can convert MSG to EML without Outlook installed using a specialized tool like BitRecover MSG to EML Converter Wizard.

EML is a generic format that opens in Thunderbird, eM Client, Windows Mail, and often used by most webmail import screens. EMLX is Apple Mail's version of such a format. EMLX should be used exclusively when moving data to Apple Mail.
The tool can automatically process such types of data but EML is for emails and forcing a contact information to it, is not the right way.
