I recommend that you can use the SysInspire NSF to PST Converter software, which can directly punish NSF file problems. This software recovers a corrupted Lotus Notes Archive File with all mailboxes, emails, contacts, calendars, tasks, journals, etc. And it offers all users a free trial of its software to inform the user about its working before purchasing it. This tool gives a preview of NSF file data so the user knows what type of data they are recovering. This tool supports lotus notes versions such as 10.0.1, 9.0.1, 9.0, 8.5, 8.0.2, 7.0, 6.5 and 6.0 versions. Even users can contact 24/7 customer support for any solution.
