How to Convert NSF File to PST for Outlook

Written by Rohit Singh

IBM/Lotus Notes and Microsoft Outlook are the two most used email applications in businesses. However, many customers must move from Lotus Notes to Outlook as their email client in some cases. However, reading an NSF file directly in Outlook is not feasible since the database file formats (NSF for Notes and PST for Outlook) are incompatible.

Let us go through the requirements as well as the process for accessing NSF emails in MS Outlook.

What are the reasons for converting from IBM Notes to Microsoft Outlook?

There are several reasons for migrating email data from Lotus Notes to Outlook.

  • When compared to Lotus Notes, Outlook is less expensive.
  • Outlook has lower operating expenses than Lotus Notes.
  • Outlook is a component of the Microsoft Office Suite, whereas Notes is a stand-alone program (need to purchase)
  • Outlook allows users to configure several accounts at the same time.
  • Outlook allows offline access to mailboxes, but Notes does not.
  • Outlook has more security features and data management procedures than Notes.
  • Lotus Notes is not as user-friendly as Microsoft Outlook. Outlook is appropriate for both novice and experienced users. Lotus Notes is tough to use for inexperienced users.
  • Another cause is a job change, as the new workplace may use Outlook as an email client.

Why Should You Convert NSF to PST?

While there are compelling reasons for Notes users to migrate to Outlook. Because NSF files utilize distinct file formats to save their mailbox data, they cannot be viewed directly in Outlook (Lotus Notes uses NSF file format while Outlook uses PST file format).

Converting NSF Files to PST Files By Hand

It is a freeway of converting NSF to PST. It is advised that you have a backup copy of the original IBM Lotus Notes NSF file before doing the manual conversion, as the file may be damaged during the process. The conversion of NSF files to PST files is done manually in two steps.

  1. Lotus Notes NSF files should be exported to an intermediate CSV file.
  2. Open MS Outlook and import the intermediate CSV file.

Step 1: Convert NSF files to CSV format.

Follow the instructions below to export NSF files from Lotus Notes.

  • Start the IBM Lotus Notes application.
  • Select file> Open > Louts Notes Application from the File menu.
  • Browse for the appropriate NSF file in the Open Application box and click Open. The NSF file you specified is opened.
  • Select Export from the File menu
  • Enter the file name, file location, and saving type in the Export dialogue box.
  • For the file, choose the Comma Separated Values format.
  • The CSV Export dialogue box appears. From the How much to Export, Export Character Set, and Detail to incorporate sections, choose the appropriate choices. Click the OK button.
  • The exported data is stored as a CSV file at the specified location.

Step 2: Open Outlook and import the CSV file.

Follow these procedures to import the Intermediate CSV file into MS Outlook:

  • Open the Microsoft Outlook application.
  • Click Open & Export, then Import/Export from the File menu.
  • A dialogue window called Import and Export Wizard appears. From the choices, choose Import from another application or file. Next should be selected.
  • Click Next after selecting Comma Separated Values as the file format.
  • Select the directory for the CSV file produced previously with Lotus Notes’ Export command by clicking Browse. You can choose the choices that best suit your needs.
  • Click Next after selecting the Outlook folder where you wish to keep your exported data.
  • In the Import a file dialogue box, check the appropriate checkbox and click Finish. By selecting the same name choices, you may easily modify your destination or map custom fields.

Manual Methods Have a Few Drawbacks

While the free NSF to PST conversion technique is useful in some cases, it also has some drawbacks. Here are a few examples:

  • For a beginner user, this is a complicated and time-consuming approach
  • It takes a long time and does not move all of the data.
  • The potential of a manual mistake exists.
  • If not treated properly, the NSF file may get corrupted.
  • An instance of data loss or partial data export can occur.
  • It is not feasible to convert selectively.
  • Only converts one NSF file at a time, making the process slow and tedious.
