So, there are 3 offices now.

- Office(1): The office we know: Word, Excel, etc. The current version is "Microsoft Office 2024" with a one-time lifetime licence.

- Office(2): Similar to Office(1), but with a subscription model. This was renamed "Microsoft 365" in 2022.

- Office(3): 'Hub' app for managing Office (1), similar to Unity Hub. This was renamed the 'Microsoft 365 app' in 2022. This was renamed the 'Microsoft 365 Copilot app' a few days ago.

Too make it more confusing:

- microsoft.com/microsoft-365/get-started-with-office-2024 redirects to Office(1).

- microsoft.com/microsoft-365/microsoft-office redirects to Office(2), stating that "Office is now Microsoft 365".

- office.com redirects to Office(3).
