Microsoft 365 vs. Office 365 - Getting the Terminology Right

Sharepoint and Office 365

In last week's article, we talked about the changing role of M365 within organizations, how it is
governed, and how it connects with other content management solutions. Given its rapid evolution and adoption – particularly with the maturation of Office 365 and Cloud versions of SharePoint, we probably should have made a few points about brand terminology. With similar names, "Microsoft 365" and "Office 365" are sometimes used synonymously by users. They are actually different. What's the difference? Let's take a look:

The confusion may have started in 2017 with Microsoft's release of Microsoft 365. This new offering bundled a group of their existing products under one license. One of the products included in the bundle is Office 365...you can see where terminology confusion set in. Let's clear things up with the infographic below:

Microsoft 365 vs. Office 365 What are the Key Differences?

  • Office 365:
    • A cloud-based suite of apps and services centered around business productivity
    • Includes apps and services like Skype for Business, SharePoint, OneDrive, Teams, Yammer, Planner, etc
    • Priced as a monthly, per-user subscription (Multiple Plans)

  • Microsoft 365
    • A bundle of services that includes Office 365
    • Includes Office 365, Windows 10 Enterprise, Enterprise Mobility + Security (EMS), and machine learning
    • Multiple plans to choose from depending on your needs

What is Office 365?

Office 365 is a cloud services platform that offers Microsoft products like Word, Excel, PowerPoint, and OneDrive, along with other productivity services like Microsoft Teams, either online or on-premises via a subscription plan.

What is Microsoft 365?

Microsoft 365 is an all-in-one bundle that includes the Office 365 suite, Windows 10 Pro, and Enterprise Mobility+Security for a complete, interconnected experience. The enterprise version of Microsoft 365 is designed for organizations that need a single platform to share and collaborate without risk, which offers data security built on top of Windows 10 Pro and Office 365.

On April 21, 2020, the consumer and small business plans of Office 365 were renamed Microsoft 365, which emphasizes productivity features and services outside of the core Microsoft Office software suite. The Office 365 brand remains in use for plans catered towards enterprise markets, and as a term for the rolling release version of the Microsoft Office software that is distributed as part of the services.

I hope this helps to understand the Microsoft nomenclature.
