This is not big point to install MS Outlook then perform EML to PST conversion. So I prefer MailsDaddy EML to PST converter, which smoothly convert EML files into Outlook PST format without Outlook installation. The tool embedded features gives you accurate and error free migration from EML based email client such as Outlook express, Window live mail, Apple Mail, Entourage, and Thunderbird to Outlook. This EML to PST converter tool included with several conversion format including PST as well as keeps folder infrastructure, data intact and attachments.
