If you’re looking to restore multiple Outlook PST files, the easiest way is to use a professional recovery tool like SysInfo Advanced Outlook Recovery. Unlike the built-in Scanpst.exe (which often fails with heavily corrupted files), this software can repair and restore several PST files at once without losing your data. It recovers everything like emails, contacts, calendars, tasks, notes, journals, and even attachments, while keeping the original folder hierarchy intact. The tool also supports different recovery modes (Standard, Advanced, and Deep) to handle all levels of corruption, whether minor or severe.
