How do I Convert my NSF files to PST for free in 2025?

If you need to convert NSF files to PST format in 2025 without spending money, there are a few manual methods you can try. However, it’s important to understand that manual methods come with significant limitations, including potential data loss, formatting issues, and a time-consuming process.

Manual Methods to Convert NSF to PST

Method 1: Using IBM Notes Export Feature

IBM Notes provides a built-in Export feature that allows users to save their emails in CSV (Comma-Separated Values) format. This exported file can then be imported into Outlook using its Import/Export Wizard. Follow these steps:

  1. Open IBM Notes and go to the mailbox containing the NSF data you want to export.
  2. Click on File > Export and choose CSV format as the output type.
  3. Select the destination folder and save the CSV file.
  4. Now, open Microsoft Outlook and navigate to File > Open & Export > Import/Export.
  5. Choose Import from another program or file, then select CSV as the import format.
  6. Follow the prompts to map the fields correctly and complete the process.
Drawbacks of the Manual Method:
  • Loss of email formatting and metadata.
  • Folder hierarchy is not maintained.
  • Attachments are not transferred.
  • Risk of data corruption.
Method 2: Using Microsoft Transporter Suite

Microsoft offers the Transporter Suite, which allows users to migrate Lotus Notes data to Outlook. However, this tool is outdated and only supports older versions of Lotus Notes and Outlook, making it impractical for most users today.
