here are the easy steps on how to import Lotus Notes to Office 365 in 150 words:

Install a third-party migration tool. There are many tools available, such as Shoviv Lotus Notes to Office 365 Migration Tool.
Add your Lotus Notes NSF files to the tool.
Select Office 365 as the destination.
Configure the migration options.
Start the migration process.
The migration process may take some time, depending on the size of your data. Once the migration is complete, you can access your Lotus Notes data in Office 365.
Here are some additional tips:
Make sure that you have a backup of your Lotus Notes data before you start the migration process.
If you have a large number of Lotus Notes files, you may want to migrate them in batches.
You can also use the IMAP migration method to import your Lotus Notes data to Office 365. However, this method is not as reliable as using a third-party migration tool.
I hope this helps!
