Frequently Asked Questions Regarding OST to NSF Converter

Softaken OST File Exporter system requirements document Windows only — they do not list Lotus Notes or HCL Notes as a prerequisite for exporting NSF files. The tool creates NSF mailbox files that you can save to any location of your choice. To open or work with the NSF in HCL/IBM/Lotus Notes, you need a supported Notes client; Softaken does not state that Notes must be installed on the same PC to perform the OST-to-NSF export itself.
Softaken states that all Outlook version OST files are supported and that exported NSF data can be read on every edition of Lotus Notes (including IBM Notes). The product page and OST File Exporter docs do not publish a specific list of HCL Notes 12/11/10 or IBM Notes 9 / Domino Server build numbers — use the evaluation edition to confirm support with your Notes environment.
Softaken OST to NSF Converter is built for offline Outlook OST files and does not require Outlook configuration — which covers disconnected or orphaned OST scenarios where Exchange/Outlook is unavailable.
