How to Convert NSF to PST - Step-by-Step Guide
EdbMails NSF to PST Converter provides a guided workflow for exporting supported Lotus Notes, IBM Notes, and HCL Notes offline NSF mailbox data to Outlook PST. Review the current EdbMails system requirements for the supported Notes and Outlook environment before starting the conversion. The software is capable of converting a wide variety of data from NSF files, including emails, contacts, calendars, tasks, notes, journals, and more, preserving the integrity of each item during the conversion process.
In addition to PST conversion, EdbMails provides separate migration workflows for supported Microsoft 365 and Exchange Server targets. If one of those live platforms is the final destination, use the dedicated migration workflow rather than creating an intermediate PST.

EdbMails ensures that the original folder hierarchy is maintained throughout the conversion process. The converter is designed to retain supported folder organization and message properties during export. After conversion, validate representative folders, messages, attachments, contacts, and calendars in the destination PST.
This step-by-step guide covers everything you need to know to successfully convert NSF files to PST. It explains the entire process, from opening the NSF file to previewing the mailboxes and their contents, and finally exporting the required mailboxes to PST format. Whether you’re a beginner or an experienced user, this guide will ensure that you can perform the conversion easily.
