This utility converts EML email message files to PST format for Outlook. It creates one or more PST files depending on the user's settings for a large number of EML files located in various folders. The tool is free to use.

For instance, when converting EML messages, this tool allows you to split your resulting PST files by size or year. EML and EMLX formats are commonly used by different email clients, such as Windows Live Mail, Mozilla Thunderbird, Apple Mail, among others, but Outlook does not work directly with these formats. Hence, you either import the files into Outlook or convert them to an Outlook-friendly format.
Outlook relies on PST data files to store email, and after converting messages from EML to PST, the resulting data file can be opened in Outlook. The messages in the resulting PST files will be the same as if you received them directly in Outlook, with all images, HTML formatting, attachments, and headers retained in their original form.
When converting, source EML files can be moved to another folder, and when you rerun the utility on the same source folder, no duplicate messages will be created in PST files. The need to save messages from cloud or NAS to local PST files, creating a separate PST file for each year, month, or day is a common instance where EML to PST conversion is necessary. Additionally, migrating old user mailboxes without importing them and connecting them to Outlook requires this kind of conversion.
Conversion of messages from EML to PST is used for migrating or preparing to migrate an old email database from EML format to Outlook and Exchange Server mailboxes. Folders with EML files allow you to estimate the size of the new message database and migrate the data in parts. This tool has excellent command line capabilities for converting EML to PST by schedule or batch files. With the command line, you can create mail migration scripts for any number of users in organizations of all sizes.
In summary, this utility is reliable, efficient, and easy to use when converting email message files from EML to PST format for Outlook. It is an essential tool for anyone looking to migrate email databases from EML to Outlook or Exchange Server mailboxes. With its different settings and command-line capabilities, this tool provides maximum flexibility, making it suitable for organizations of all sizes.
