Question:
I recently switched from IBM Lotus Notes to Microsoft Outlook for work, but I have several NSF files from my old system. Is there a safe way to open these NSF files in Outlook without losing any data or formatting?
Answer:
You can’t open NSF files directly in Outlook because they use different data formats. The best way is to convert the NSF files to PST format, which Outlook supports.
I’d recommend using eSoftTools NSF to PST Converter Software. It can easily convert NSF emails, contacts, calendars, tasks, and attachments into PST format while keeping folder hierarchy and metadata intact.
The tool also provides a preview option before conversion and supports exporting to multiple formats like PST, EML, MBOX, MSG, HTML, and others.
