Q - How can I convert Lotus Notes NSF files to Outlook PST without losing my folder structure?
A - That's the number one worry with this kind of migration, isn't it? You spend years organizing your emails into folders and subfolders, and the thought of them all being dumped into one giant inbox is a nightmare.
The good news is, yes, you can absolutely preserve your folder structure.
While manual methods are risky and often fail here, a specialized converter tool is designed for this exact problem. For instance, when I was managing a migration, I found the eSoftTools NSF to PST Converter to be incredibly reliable. The whole point of a tool like that is to mirror your original mailbox. It scans the NSF file, understands the hierarchy (Inbox, Sent, and all your custom folders), and then rebuilds that exact same structure in the new Outlook PST file.
When you open the new file in Outlook, it should look just like your old Lotus Notes setup—attachments, read/unread status, and all.
