The safest method to convert NSF files to MBOX format—while ensuring complete data preservation including attachments, inline images, and email formatting—is to use a professional third-party converter like eSoftTools Lotus Notes to MBOX Converter Software. Manual methods are limited, prone to error, and often don’t support the full fidelity of rich content found in NSF emails. Tools like eSoftTools offer preview functionality, folder selection, and batch processing options which help maintain original structure and styling.
Additionally, with eSoftTools, users can retain meta properties (To, From, Subject, Date, etc.) and preserve the folder hierarchy exactly as in Lotus Notes. It also allows selective export, so you don’t have to convert unnecessary folders. For users who deal with critical email data (especially for business use), using a purpose-built tool is the most reliable and risk-free approach.
