The software eSoftTools Software updates the process of recovering your PST file. This program can swiftly repair PST files and Outlook PST mailboxes, as well as restore all P folders that are missing. MS Outlook 2003, 2007, 2010, 2013, and 2016 were all supported by PST Recovery. PST Recovery software is available for download as a free trial edition. When I was satisfied with the software's discoveries, I upgraded to the full version, which allows you to recover 25 emails from each PST folder.
