To repair a corrupted Outlook PST file without losing data, first create a backup copy of the original PST file to protect your mailbox data. You can try Microsoft Outlook’s built-in ScanPST.exe, but it may not recover all items when the PST is severely corrupted or inaccessible. In such cases, the Aryson Outlook PST Repair Tool can scan and recover data from damaged PST files without requiring Outlook. The software provides Standard, Advanced, and Deep recovery modes based on the severity of corruption. It can recover emails, contacts, calendars, tasks, notes, and other mailbox items while maintaining the folder hierarchy. After scanning, you can preview the recovered data and save it as a new PST file or export it to formats such as EML, MSG, MBOX, or DBX. A date-range filter is also available for selective recovery.
