The best way is to use a reliable PST recovery tool when the damaged PST cannot be repaired with Outlook’s built-in ScanPST.exe. Aryson Outlook PST Repair Tool can scan damaged or inaccessible PST files using Standard, Advanced, or Deep recovery modes, depending on the corruption level. It can recover emails along with contacts, calendars, tasks, notes, and other mailbox data while preserving the folder structure. After scanning, you can preview the recoverable data and save it in formats such as PST, EML, MSG, DBX, MBOX, or Archive. The tool also supports encrypted and password-protected PST files, ANSI and Unicode PST files, and oversized PST files. For selective email recovery, its date filter can help save specific mailbox items based on a chosen date range.
