First thing first, there is a manual solution available that can be used to migrate Lotus Notes to Office 365. But the problem with this method is you first have to convert NSF to PST format and then
import PST to Office 365. But I suggest using Shoviv Lotus Notes to Office 365 migration tool for better and desired results.
