There are two approaches for NSF to PST Conversion. One is manual and other is using a third-party tool.
- Launch the Lotus notes and go to NSF Database.
- Export the NSF database to CSV format or structured text.
- Import The CSV file into the Outlook using Import feature.
Manual methods can be used but sometimes these are very lengthy and tedious for novice users. So, these users can use a third-party tool.
However, if you are comfortable with manual method, try that.
