Manual Way to Convert NSF to PST Format Effortlessly

NSF to PSTNSF to PST conversion becomes a necessity if you’re migrating from Lotus Notes to Outlook. Though both are popular email client applications but use different file formats to store mailbox data, i.e. Lotus Notes uses NSF and Outlook uses PST in Outlook. You can’t export your emails from Lotus Notes to Outlook directly without converting NSF to PST format. Luckily, there’s a manual trick to migrate from Lotus Notes to Outlook.

Lotus Notes (now known as IBM Notes), developed by IBM, is an application suite just like Microsoft Office suite. It contains many components, such as e-mail, calendar, and schedule, address book, database, web server, and programming. Being an email application, Lotus Notes is very popular among users. Lotus Notes uses database files which are saved in the Notes Storage Facility (NSF) format. In this type of format, data are stored in document units called notes.

Notes can store the collaborative business information, such as emails and calendar data.

Sometimes you may require accessing your NSF files’ data in Windows Outlook, but this is a quite challenging task for users as both these programs (Lotus Notes and Outlook) support different file formats. Lotus Notes understands NSF aka notes storage facility format while Outlook doesn’t understand such format. Microsoft Outlook client creates an Outlook data file in PST aka Personal Storage Format. So, if you want to access your NSF files’ data in Microsoft Outlook, you need to convert them into PST format. But now a question arises here:

  1. Exported NSF data from Notes 8.5 includes email sender name, subject and date only. These import fine into Outlook 2013/ Office 365, but none of the messages include any body information.

  2. Undeniably, the manual method to export NSF to PST described in this article is useful. But in some cases, it does not work. So alternatively users can take help of any professional NSF to PST Converter tools which extracts each and every mail component present in Lotus Notes file and exports it Outlook importable PST file.
