There are two methods for importing EML files into Outlook PST. The first one is the manual method and the other is using an automated tool. The manual method requires a lot of technical skills and cannot process multiple files at a time, while an automated tool is easy to operate by any user and can process numerous files at a time with instant processing. An automated tool is a much safer and more reliable method as it protects the data from loss and corruption during the conversion and provides accurate results. I can advise that you try the Toolsbaer EML to PST converter, which converts EML files into PST file format effortlessly with just a few clicks. It is compatible with all versions of the Windows OS and Mac OS and has a basic interface.
