If you’re looking for a reliable way to convert NSF to EML without losing data, I’d strongly recommend using a professional tool like eSoftTools NSF to EML Converter Software. I recently used it during a corporate migration project, where we had to move thousands of emails from HCL Notes (Lotus Notes) to a system that supports EML format — and the tool worked flawlessly.

What really impressed me:

  • Preserves complete data integrity – The tool maintained original folder hierarchy, email formatting, inline images, and metadata like timestamps, sender info, and subject lines. Even embedded attachments and hyperlinks were retained after conversion.
  • Selective folder export – You don’t have to convert the entire mailbox. It allows you to preview the NSF content and pick only specific folders (Inbox, Sent, Custom folders, etc.) for export. This helped reduce clutter and saved time.
  • Supports encrypted NSF files – Some of the NSF files I worked with were password-protected, and the tool was able to open and convert them after authentication, without any issues.
  • Batch conversion option – You can convert multiple NSF files at once, which is a huge time-saver if you’re working in an enterprise or handling large volumes of mail data.
  • Simple, clean interface – Even for non-technical users, the UI is intuitive. You just load the file, choose what you want to convert, pick the output format (in this case, EML), and hit Convert.
The converted EML files were 100% compatible with email clients like Thunderbird, Windows Mail, and others. Plus, it doesn’t require Lotus Notes to be installed on the system, which was convenient.
