Hi @aero2466

There is a difference between Office 365 and Microsoft 365. Office 365 is a set of cloud based business applications like Exchange, Office Apps, SharePoint, OneDrive. It is a part of Microsoft 365. Microsoft 365 is Office 365 with Windows 10 (OS) and the Enterprise Mobility Suite (Suite of Security and Management apps).

Lots of information on this in articles online including


Hope that helps and answers your question!

To add: not all Microsoft 365 include Windows 10. Microsoft 365 Basic, for example.

This is just even more confusing, I got a message on my Computer saying: Microsoft 365 is the new Office 365. I pay a yearly Subs of $129 or something for Office 365 with 5 licences but does anyone have any concrete idea of what that gives me now with MS 365? Is that price going to up without any additional benefit? I already have so many WIN Pro licences anyway.
Why can't they do what Apple does with a free macOS (that is STABLE, does not need daily updates) and has PAGES, NUMBERS, KEYNOTE and MAIL included for free?

@JJJ123 Please refer https://www.microsoft.com/en-in/microsoft-365/office-365 


 "We changed the name to be more reflective of the range of features and benefits in the subscription, to meet the unique needs of individuals and businesses."


"Microsoft 365 includes everything you know in Office 365. Microsoft 365 is designed to help people and businesses achieve more with innovative Office apps, intelligent cloud services, and world-class security."
