It’s easy to see how the two products can be confused. It gets even more confusing when you learn Microsoft 365 includes Office 365.
The Short Version
Office 365 is a cloud-based suite of productivity apps like Outlook, Word, PowerPoint, and more. Microsoft 365 is a bundle of services including Office 365, plus several other services including Windows 10 Enterprise.
The Long Version
Office 365 is a cloud-based suite of apps and services centered around business productivity. It includes some apps you’re probably already familiar with like Microsoft Outlook, Word, PowerPoint and Excel.
Depending on the plan you get, subscriptions also include apps and services like:
- Skype for Business
- And much, much more, along with robust productivity, collaboration, and security features.
Office 365 is a per-user subscription licence.
Microsoft 365 is a bundle of services that includes Office 365. It also includes Windows 10 Enterprise, Enterprise Mobility + Security (EMS), and machine learning.
The services included in Microsoft 365 are also available as separate licenses. If you can’t find a plan that fits your needs, you can still achieve close to the same results by buying licenses for all the components (though you may miss out on some of the machine learning benefits).
Office 365 is also per-user subscription licence.
