Introduction
IBM Notes (also known as HCL Notes) is a popular tool for email communication and data management. That explains why some users have to face NSF to PST conversion, even though Microsoft Outlook remains one of the most well-known email tools for various business organisations all over the world.
Depending on their specific needs, users can choose between numerous migration utilities available in this sphere and also to evaluate the most popular options, such as SysTools Export Notes. The present article compares six applications that can be used to migrate Lotus Notes mailbox data, while keeping the original emails intact and preserving folder structure.
What is NSF to PST Conversion?
The native database file format used by HCL Notes (formerly known as IBM Lotus Notes) for storing e-mails, contacts, calendars, journals, and other data is called NSF. The Microsoft PST (Personal Storage Table) format is the mailbox file format that is used by Outlook.
The conversion process refers to the extraction of mailbox data from the NSF databases in a way that allows the user to save this data in PST format so that it can be opened and managed in Microsoft Outlook.
The migration allows users to transition from the HCL Notes environment to the Microsoft Outlook environment without losing any important mailbox data.
