  2. Use automated software to Import Notes to Outlook

Both are the best Methods of importing NSF files to Outlook. Users can choose anyone from these two options. But, before conducting the Manual Method.

Manual Method

I know users definitely use the Manual way because this Method can be performed without spending a single penny. This method is totally free of cost. This can be done in Lotus Notes itself, but you need to know the fact that this method takes a longer process and the user must know about these steps. A single mistake can break the NSF file and there is a risk of database corruption. So the Manual Method is safe for those who know everything about Lotus Notes. A single mistake can lose the data of the NSF file during the exporting process and ruin the structure of the NSF file after the exporting process is done. 

Do not attempt this manual procedure, If you have multiple Lotus Notes NSF files that need to be converted into Outlook. For this situation, we always recommend going with an expert software solution and completing the migration process without losing any single data.

Steps for Manual Method

  • First, open the Lotus Notes application and open the NSF file that you need to open in Outlook.
  • Tap on the file menu and click on the Export option.
  • Select the CSV(comma-separated value).
  • After that, you will see the dialog box to choose the file and browse the location to save the converted file
  • Select your file type from the save as drop-down menu.
