To import EML files into Outlook, I would like to recommend using CubexSoft EML to PST Converter Tool, which is the most powerful tool to effortlessly convert EML files into PST format without any data loss. You can easily convert an EML file into different file formats like PDF, MSG, MBOX, and others. It is fully compatible with multiple EML-based email clients like Mozilla Thunderbird, Outlook Express, eM Client, and many more. Additionally, you can run this tool on both Windows and Mac operating systems. The software provides a user-friendly interface that makes it easy to use for all users. Also, you can easily access EML files in all Outlook editions like 2021, 2019, 2016, 2013, 2007, 2003, and others.
