Manual Method to Export Lotus Notes to Outlook  

It is in-broad, a two-phase process. Firstly, users need to go through a few steps on Lotus Notes, and then they are required to follow a few more steps on MS Outlook. The manual technique requires users to convert NSF to CSV and then the CSV to Outlook PST. the steps are as follows:

Phase1: Make CSV of Lotus Notes Items

  • Install Lotus Notes on your system.
  • Open mails, contacts, calendar, to-do list, notebook, and select those items you want to export.
  • Go to the File option and hit on Export from the list.
  • Choose a path for the same, and; select CSV in the file type from the dropdown list.

These are the steps to convert the NSF file of Lotus Notes into CSV (comma-separated values). Now we will import so-formed CSV files into Outlook.

Phase2: Import CSV in Outlook

  • Hit the File menu from the ribbon bar and click the Open&Export option and consequently click the Import/Export option
  • A wizard will appear, select “Import from Another Program or File option” from the dropdown list, and hit Next.
