Today’s digital era demands email management for communication on both personal and professional levels. Many email users wish to migrate their whole mailbox to a broad platform because of company needs, technical reasons, or email client shifts. A commonly seen scenario involves converting the EML email file data to a professional email platform like HCL Notes (also known as Lotus Notes or IBM Notes) which uses the NSF format for email, to-do lists, contact lists, and other data storage. We will explore the solutions to convert EML to NSF in this blog post, besides the reasons for the data conversion.

Reasons for EML Data File Conversion to NSF

Many reasons necessitate the email data conversion from EML file format to the Lotus Notes NSF format, and the following points describe some of them:

  • Migration to HCL Notes: The first and most important reason to export EML email file to NSF format is migration to HCL Notes (or Lotus Notes). Many EML file users with email accounts on Microsoft Outlook or Mozilla Thunderbird (external email accounts) wish to migrate their entire mailbox data to HCL Notes due to organizational requirements and security. Moreover, it ensures email continuity and archive accessibility due to the Domino Server backup for the NSF data file.
  • Email Data Security: Another reason to convert EML to NSF is email file security. IBM Notes (or HCL/Lotus Notes) provides robust data safety features like password encryption, and access control lists, which makes the NSF file more extensively secure for email accessibility. On the other hand, EML files lack built-in email encryption and password security and are vulnerable to malware and harmful scripts. Hence, EML data conversion to NSF becomes imminent.
  • Centralized Integration and Collaboration: The third reason to export EML email file to NSF format is quite direct: centralized integration. Email users working with HCL platforms on an enterprise level can migrate their EML data to the NSF format for interoperability, therefore enhancing the professional workflow and productivity. Moreover, being a complete collaboration platform makes HCL Notes (or Lotus Notes) packed with features like task management and automated workflow creation.

These features necessitate immediate EML file conversion to NSF, and the following section explores the solutions for the same.
