Two Free methods to convert NSF files into PST files

Two major email clients prevalent in organizations are IBM/Lotus Notes and MS Outlook. However, under certain situations, many users need to switch their email client to Outlook from Lotus Notes. But accessing NSF file directly in Outlook is not possible. Let us go through the necessities, and the procedure one has to follow to access their NSF emails in MS Outlook.

What are the reasons for IBM Notes to MS Outlook migration?

Migration of email data from Lotus Notes to Outlook is attributed to various reasons.

• Outlook is cost-effective when compared to Lotus Notes.
• Outlook allows users to configure multiple accounts simultaneously.
• Lotus Notes is less user-friendly than MS Outlook. Outlook is suitable for the novice user as well as technically sound users. Novice users find it difficult to work with Lotus Notes.
• Job switch is another reason as the new working place may have Outlook as email client.

Why NSF to PST Conversion?

While there are enough reasons for Notes users to switch to Outlook, NSF files cannot be accessed directly in Outlook as they use different file formats to save their mailbox data (Lotus Notes uses NSF file format while Outlook uses PST file format).

To access the whole email data, first NSF files have to be converted into PST files. There are primarily two methods to convert NSF files into PST files – manual method and third-party tool i.e. Kernel for Lotus Notes to Outlook.

Manual Method to Convert NSF files into PST files

1. Export NSF files from Lotus Notes to an intermediate CSV file
2. Import the intermediate CSV file into MS Outlook

8. The exported data gets saved in CSV file gets saved in the defined location.

Step II: Import CSV file into Outlook

Import the Intermediate CSV file into MS Outlook by following the steps:

• Complicated and tedious method for a novice user
• Time-consuming and fails to migrate entire data
• If not handled correctly, might cause corruption in the NSF file
