If you’re trying to convert NSF to PST but don’t have Lotus Notes installed, I found a good option: eSoftTools NSF to PST Converter Software. It supports NSF file conversion even when Lotus Notes is not installed, which saved me a lot of hassle. The tool is designed with a built-in preview feature, so you can view the contents of the NSF file before converting—emails, contacts, calendars, everything stays intact.
I tested it with a 2GB NSF file, and the software handled it smoothly. It let me export the entire data into a PST file that I could open directly in Outlook. The interface is user-friendly, and even for someone with limited tech skills, it was easy to follow the steps. This tool is a good choice if you’re moving from HCL Notes to Outlook but no longer have the Lotus Notes program.
