Before moving on to the methods, let us first describe some reasons that led us to NSF to PST conversion.

Reasons to Convert NSF to PST

There are many reasons that can lead you to convert NSF files to Outlook PST, some of which are mentioned below.

Expensive: Outlook is a part of Microsoft Office, so there is no need to buy Outlook separately. It is also available at a very reasonable price in the Microsoft Office Suite. However, when we compare Outlook to Lotus Notes, we need to pay more to purchase it externally.
