HCL Notes, formerly known as IBM Lotus Notes is an advanced information management system that allows you to manage emails and other mailbox items. It saves your mailbox in multiple NSF files for different types of data (contacts, emails, etc.). Microsoft Outlook is also an information management platform that offers a wide range of features for fulfilling the same requirements. However, it’s more refined, complex, and resourceful.

Essentially, Lotus Notes isn’t a messaging platform but rather an application/development platform that offers support for email management. Outlook, on the other hand, is a comprehensive messaging platform that offers much better support for emails, contacts, meetings, etc. It also offers unmatched performance when used with Exchange.

Many Lotus Notes users migrate to Outlook for a better experience. Some common reasons for this migration are:

  • Outlook offers the best support for Exchange Server
  • You can install a wide range of add-ins in Outlook to customize it as per your requirements
  • Finding technical support is easier for Outlook
  • Outlook offers a more polished and refined UI

In the process, they search for answers to how to view NSF file in Microsoft Outlook or how to convert multiple NSF files to PST. Below, you will find two viable solutions.

Since Microsoft Outlook doesn’t support the Notes Storage Facility (NSF) format, you need to convert your NSF files into PST or CSV format. There are two methods to convert NSF:

1. Manual Method

In the manual method, you need to export the NSF data to a CSV file and then import the CSV file into Outlook. To apply this method, follow these steps:

  • Open IBM Lotus Notes and open the NSF file you want to view in Outlook.
  • Open the File menu and click the Export option.  
  • In the Export window that opens, provide a location for saving the CSV file, and assign a name to the CSV file.
  • In the Save as type menu, select the Comma Separated Value option and click Export.
NSF Export Options
  • In the CSV Export window that opens, select the appropriate options and click OK. The NSF data will be saved in a CSV file in the provided location.
  • Open Outlook and go to File > Open & Export > Import/Export.
  • In the Import and Export Wizard that opens, select the option Import from another program or file and click Next.
  • In the Import a File window, select the option Comma Separated Values and click Next.
  • Click the Browse button to provide the location of CSV file. Select appropriate option under Options and click Next.
Import a File Window Outlook
  •  Select a folder in your Outlook mailbox where the CSV file will be saved and click Next.
  •  Click Finish.

Limitations of Manual Method:

  • Consumes a lot of time
  • Cannot convert multiple NSF files at the same time
  • Not possible to extract entire email items into Outlook
  • You have to apply many technical steps
  • A mistake during the procedure can result in data loss
  • You can’t convert multiple NSF files at the same time
  • Batch conversion and Office 365 Import is not possible

2. Automated Method

As mentioned above, in the manual method, you have to apply many technical steps to view NSF in Outlook. As an alternative, you can use a third-party application to open NSF in Outlook. For instance, you can use Stellar Converter for NSF to convert Lotus Notes NSF files into PST format directly and quickly.
