NSF files are proprietary to IBM Notes, making it difficult to open them without the software installed. However, there are still a few ways to access their contents. One method is to use an NSF Viewer—these are free tools that allow you to open and read NSF files, but most lack export functionality. Another method is to convert NSF files to PST or EML, allowing them to be accessed in Outlook or other email clients.
A more effective approach is to use eSoftTools NSF to PST Converter, which allows users to open and preview NSF files without Lotus Notes. This tool offers a built-in preview mode where users can browse their emails, contacts, and calendar items before deciding to export them. It also supports multiple output formats, including PST, EML, MBOX, and MSG, making it easy to migrate NSF data to different platforms. This is especially useful for users who have old NSF files but no longer have access to IBM Notes.
