EML is an acronym for ‘Email Message’ and is developed by Microsoft Corporation. By default, EML files can be opened in Outlook Express (came preinstalled with Windows XP OS). The EML file format follows a standard structure; it usually contains a header and the message body. Due to compliance with the standards for email, EML files can be used with various third-party applications, servers, and email clients.
By default, if you have installed Outlook 2010 or later versions on your machine, EML files will open in Outlook. If you are unable to open it, you can make them open in Outlook by making it the default program.
However, if you’re using Outlook 2003 or 2007, you will have to change the registry settings to open EML files in Outlook.

Reasons to Open EML files in MS Outlook
Over the years, many people must have used various email clients such as Outlook Express, Windows Live Mail, etc. which have now become obsolete. Hence many users are now migrating from these email clients to MS Outlook as it now offers many advanced features. Please note that the EML format uses email clients that work on Windows platforms. Sometimes, with OS release, Microsoft keeps on changing the default email clients. For example, in earlier versions of Windows OS like XP, Outlook Express was the default email client, but in the later versions of Windows like Vista and 7, Outlook Express was replaced with Windows Mail and Windows Live Mail. All of these three email clients support different file formats; hence, it becomes essential to open EML files in MS Outlook.
