Lotus Notes NSF files can become corrupted due to large file sizes, sudden shutdowns, or hardware failures. While IBM Notes offers built-in repair tools like Fixup, Compact, and Updall, these do not always work for severely damaged NSF files. In such cases, eSoftTools NSF to PST Converter can scan, recover, and restore corrupted NSF files without losing data. Users can extract emails, contacts, and attachments and save them in different formats like PST, EML, and MBOX. This allows users to open and access their data in different email applications without any technical issues.
