For large Outlook PST files, the best recovery method depends on the level of corruption. Start by creating a backup of the original PST file and using Microsoft's ScanPST.exe utility to fix minor errors. If the file is severely damaged, oversized, or inaccessible, an advanced recovery solution may work better. SysInfo PST Recovery Tool offers three recovery modes: Standard for minor corruption, Advanced for moderate damage, and Deep for more complex corruption. It helps recover emails, attachments, contacts, calendars, and other mailbox items while maintaining the original folder hierarchy. The software also supports large PST files, including files up to 80 GB, and allows users to preview recovered data before saving it. Additionally, you can apply date-range filters and export recovered mailbox data into PST, EML, MSG, and MBOX formats. For heavily corrupted or large Outlook data files, Deep Recovery is a suitable option to try.
