To recover a corrupted PST file without losing Outlook data, first create a backup of the original PST file to prevent accidental data loss. Then, use Microsoft's built-in ScanPST.exe (Inbox Repair Tool) to scan and fix minor corruption issues. If the utility fails or cannot recover all mailbox items, consider using SysInfo PST Recovery Tool. It helps restore emails, attachments, contacts, calendars, tasks, and other mailbox data from corrupted, damaged, or inaccessible PST files. The software offers three recovery modes: Standard, Advanced, and Deep, depending on the corruption level. It also allows users to preview recovered mailbox data, selectively save folders, and maintain the original folder hierarchy during recovery. Additionally, you can apply date-range filters and export recovered data into PST, EML, MSG, and MBOX formats. This makes SysInfo PST Recovery Tool a practical option for recovering important Outlook mailbox data while keeping the original PST file unchanged during the recovery process.
