eSoftTools Outlook PST Recovery Software is software that streamlines the process of recovering your PST file. This application can quickly repair corrupted PST files and Outlook PST mailboxes, as well as restore all missing P folders. PST Recovery worked with MS Outlook 2003, 2007, 2010, 2013, and 2016. PST Recovery software is available as a free trial edition to download. I switched to the full version when I was happy with the software's findings, which allows you to recover 25 emails from each PST folder.
