Switching from IBM Notes (HCL Notes) to Outlook 365 is common nowadays, but manual migration is complex and risky. The safer route is using an automated NSF to PST converter.
I personally recommend eSoftTools NSF to PST Converter because it lets you convert NSF files directly into PST. Once you have PST files, importing them into Office 365 (or Outlook 365) is straightforward using Microsofts native Import feature.
The tool preserves your folder hierarchy, email formatting, attachments, contacts, and calendars during the entire process. That means no data loss or corruption, and the transition feels seamless.
The safest way to switching from IBM Notes to Outlook 365 is using a solution that can perform the switch without losing or destroying your data. Using the FixVare NSF to Office 365 Importer simplifies this process by preserving your email structure, attachments, contacts, and calendars precisely as they were. The software also provides a clean preview, allowing you to confirm everything before converting. Once this process is complete, your data shows in Outlook 365 as expected, making this process smooth and stress free.
