Users still need to adopt HCL Notes, formerly known as IBM Notes, as their preferred email client. Since Microsoft Outlook is becoming increasingly popular, many users will need to convert their NSF files to PST to be opened in Outlook. While conversion is the best long-term option for moving NSF data, other options are worth exploring if the user’s main goal is open NSF files without Lotus Notes to get answers to pressing questions.

Because of market trends like business mergers, acquisitions, and switches, as well as cost factors (high installation and maintenance costs), the complex user interface of Notes, a poor or down Notes Server, a slow backup process, benefits with other email clients like Outlook, and so on, users prefer or are required to open NSF files without using the Notes application.

Why do users seek to open NSF files without HCL Notes?

  • The high expense of upkeep
  • The need for a lot of RAM to hold NSF data items.
  • Lack of application installation, fragmented files, and a sizable database
  • Problems with the Notes server or associated problems

Which options are there, exactly?

The only program that can read NSF files is Microsoft’s Outlook, so if you’re the only person in the world who needs to read one, you’ll have to use Outlook. Instead, a time-consuming export procedure consisting of two stages is used.

Also, users can open and examine NSF files without HCL Notes using the free NSF Viewer program. There is also no requirement for an email client to access NSF files in this situation.

Let’s take a step back and compare the two approaches by seeing how they each begin to solve the problem.
