If you have only a few EML files, importing them manually is manageable, but it gets tedious when the folder contains hundreds or thousands of messages. For bulk conversion, [BitRecover EML to PST Converter]https://www.bitrecover.com/eml-to-pst/ can process multiple EML files or complete folders and save them as PST. It also retains the folder hierarchy, attachments, and email properties, so you don't have to rebuild everything in Outlook afterward. I’d recommend testing a small folder first and checking a few converted emails before processing the complete archive.
