Demystifying EML and MSG

Before exploring the process to convert EML to MSG, it is important to learn what these formats entail:

EML (Email Message File):

This file format saves a single email message in terms of headers, body, attachments, and sender information. It’s used by most email clients such as Windows Live Mail, Outlook Express, eM Client, and Thunderbird.

MSG (Outlook Message File):

In contrast to EML, MSG format is Microsoft Outlook-specific and saves a single email message together with its metadata, attachments, sender information, and formatting. The messages are saved in individual files, which can be easily shared, managed, and opened directly within Microsoft Outlook.

In short, where EML stores individual messages, MSG simplifies organization by grouping multiple emails.
