How to Import Lotus Notes NSF Files into MS Outlook

Enterprises are continuously preparing them to be as quick in their communications. In that line, if users are still on Lotus Notes Email Client, it’s time to give it a thought. While Corporates prefer Microsoft Outlook due to its popularity amongst users; Lotus Notes trails way behind.  Reason being the complex user interface of Lotus Notes. Also, Outlook profile can be accessed with multiple machines as against Notes which is can be accessed through the configured machine only. The rising popularity and ease of use have forced users to migrate from Lotus Notes to MS Outlook and import NSF files into Outlook. The only dilemma these users face is how to import NSF to Outlook because they are aware of Lotus Client NSF but lack the information on Outlook PST.


Over the years, MS Outlook has gained popularity amongst users and non-users due to its friendly interface and multiple-machine configuration.
