The most chosen and recommended method to convert Lotus Notes data to Outlook PST is by using a tool such as eSoftTools Free NSF to PST Converter Software. This can export every item in the mailbox with the ability to choose as many folders as needed and leave the rest. In addition, a simple graphical interface makes the whole process user-friendly for non-technical users. Also, the user can split PST files into multiple parts easily through its splitting feature. A free demo version is also offered to every user to make the conversion without any charges.
