Cigati NSF to PST Converter - 2026 Pricing, Features, Reviews & Alternatives

Cigati NSF to PST Converter is an email migration application that translates IBM Lotus Notes NSF data into Outlook PST format and a variety of other file formats. The software facilitates the transfer of mailbox items including messages, attachments, contacts and calendar entries from the Lotus Notes environment to Microsoft Outlook without data loss. The application operates as a standalone Windows program and requires IBM Lotus Notes to be installed on the host system.

The software supports conversion to multiple destination formats such as EML, MSG, MBOX, PDF, HTML and CSV. It enables batch processing of multiple NSF files simultaneously and preserves original folder hierarchies and message properties throughout the migration. A built-in preview mode displays email contents and attachments prior to export. Selective migration can be performed using a date range filter or an option to exclude entire folders from processing.

Advanced filters identify and remove duplicate items during conversion to optimize storage and reduce redundancy. Encrypted NSF files are decrypted automatically before export. HTML-based mailbox entries are handled through specialized formatting routines. Users can configure naming conventions for destination files and designate custom output paths. The application generates detailed log files for audit and troubleshooting purposes.

The tool supports direct migration to external email clients and cloud services including Gmail, Yahoo Mail, AOL, Office 365, Hotmail, Live Exchange and IMAP-based systems. A free demo version enables conversion of fifty emails per NSF file and allows evaluation of feature sets before licensing. The full release removes these limitations and provides unlimited migration capacity. Technical support is available around the clock through standard support channels.
