But there is a difference between these two emails clients, where NSF (Notes Storage Facility) is a file extension used by Lotus Notes, whereas Microsoft Outlook uses PST file format to store data. Nowadays, many users are switching from Lotus Notes to Outlook, seeing the changes in their business requirements and market. There are many reasons behind the conversion of the NSF file to PST format.
