How to repair PST files in Outlook? If you're encountering issues, I recommend eSoftTools Outlook PST Recovery Software, which is fantastic software. It works in a very straightforward and smooth manner. The PST Recovery is displayed in real-time during the conversion. Office365, MBOX, EML, EMLX, MSG, HTML vCard, and a variety of other file types are supported by this software. All users have access to the sample version, which allows them to convert up to 25 emails per folder.
