NSF files in Lotus Notes can get corrupted due to file size limits, sudden shutdowns, or hardware issues. While IBM Notes offers built-in repair tools like Fixup, Compact, and Updall, they don’t always fix severe corruption. eSoftTools NSF to PST Converter can scan damaged NSF files, recover emails, contacts, and attachments, and restore them without losing data. The tool allows exporting the recovered data in formats like PST, EML, and MBOX for easy access in different email clients.
