A Short Introduction of NSF File and PST File

Both the mentioned email clients create and support different file formats to store mailbox data locally. Emails and other enterprise items in IBM Notes are saved in NSF file format; whereas on the other hand, Microsoft Outlook creates a PST file to store all mailbox content. This mailbox content comprises emails with or without attachments, address book information, calendar, notes, etc.

If enterprises were earlier working on IBM Notes email clients, they cannot use the NSF database in Microsoft Outlook. It is so because the Notes database is in .nsf format, which is not supported in the Outlook mailing app. To export the database to Outlook 2019, 2016, 2013, etc., administrators have to attempt an NSF data to PST file conversion.

However, in this guide you will get all the information on how to export NSF to PST, but, before going further to the conversion process. Let us discuss the causes behind converting the files.

Why Convert NSF to PST File?

There are various reasons due to which users demand conversion of the NSF to PST file format. Below listed are some of the common causes for the same:

  • In comparison with the Lotus Notes app, MS Outlook is cost-effective software.
  • Microsoft email client enables users to configure more than one account simultaneously.
  • Former employees who are switching jobs can also look for a solution to export NSF files to PST.
  • Enterprises find Lotus Notes email client less friendly in comparison to MS Outlook. It has been found that the Microsoft desktop mailing app can be accessed by novice as well as technical users.

Though migration of the Domino server to Exchange is pretty simple, to export NSF file to PST is not at all easy. Several innumerable causes result in unknown data corruption and sudden data deletion. Therefore, we strongly recommend you to be conscious at the time of process execution. The manual method is divided into two major steps-

  1. – Exporting of Lotus Notes NSF to CSV and
  2. – Importing the exported CSV file into Outlook

Now we are going to guide you with an explanation of each step in brief.

Step # 1: Save Notes File in Structured / Tabular Text

  1. Firstly, launch the IBM Notes mail application on your system and hit on the Mail tab
  2. Then, go to the Menu bar of Lotus Notes and click on File
  3. This expands a menu in which you have to click on the Export option. This helps in continuing the procedure of NSF to PST file conversion.
  4. After that, define the location of your PC where you wish to save the resultant Lotus Notes database file
  5. In the same window, click on the drop-down button of Save As Type and select the Tabular Text or Structured Text (anyone) option

Please Note – The structured text format and tabular text format – both these file formats are compatible with the MS Outlook mail client. You have to choose only one option in Step (5). Also, if you have chosen the ‘Structured’ option, select the PST option while importing the Notes resultant file in MS Outlook. Otherwise, you’ll select the CSV option in the case of tabular file format.

At last, hit on the Export button to allow Notes to execute the exporting procedure as per the defined settings.

Step # 2: Import CSV File in Microsoft Outlook

Only when the execution of Step (1) gets finished, you will start with the below instructions:

  1. Launch Microsoft Outlook 2019, 2016, 2013, etc., email client on your PC with the profile in which NSF file is to be imported
  2. After that, hit on File >> Open and Export and from the list of options, click on Import/Export. This continues the procedure to convert NSF file to PST in Outlook app.
  3. An Import and Export wizard gets opened in which you have to select Import from another program option and hit the Next button to proceed further
  4. Now, in the current window, you have to select any one option. Your selection criteria will be based upon the file format in which you have exported NSF file in Step (1). Here, we are selecting the Comma Separated Values option. Then, click on Next 
  5. Click on the Browse button to select the resultant file from local PC storage where you have stored the NSF file after exporting it in Structured / Tabular Text file format.
  6. Finally, click on the Finish button to permit the Microsoft email client to read the selected file and import its data.

That’s it. This is how you can convert NSF file to PST manually.

Important Note – It is important to have the Domino and Exchange server connection active when administrators are migrating data from the NSF file to the PST file format.

Why Go For Complex Solution, When Simple Is Available?

Though the manual solution is free, it makes the conversion task a burden and MS Outlook must be installed on your computer. Using this method is not feasible as it will going to be a lengthy process. If you want to convert NSF file to PST manually, it takes at least 48 hours for the entire process completion if your NSF database is large. There is no guarantee of holding data integrity in the explained procedure and hence, chances of data loss are high.
