eSoftTools PST to MBOX Converter Software is one of the most excellent tools, and I strongly recommend it since it is user-friendly and straightforward to use, and non-technical and technical users can use it. It's quick and straightforward to use. It can open pst files and supports all Outlook editions, including 2019, 2016, 2013, 2010, 2007, 2003, and prior versions. At the same time, the email attributes will be preserved during the pst to mbox conversion.
