Stellar Lotus Notes to Outlook Converter Software

Lotus Notes, currently known as HCL Notes, saves the mailbox data, such as emails, contacts, attachments, etc. in NSF files. Also, when you archive or backup your emails from Lotus Notes or HCL Notes email client, the backup or archive file is saved either in CSV or NSF file format.  Unfortunately, the NSF file format isn’t supported by Outlook.
