Now that Microsoft has combined multiple products into a single solution, the question naturally arises: What’s the difference between Office 365 and Microsoft 365, and which one is right for your enterprise?

Read on to learn the basic differences between these two Microsoft platforms and how they can help boost your productivity.


What Is Office 365?

Office 365 is a comprehensive suite of productivity apps and solutions that empower your enterprise to work better and get more done effortlessly. It comprises apps like Microsoft Word, PowerPoint, Excel, Outlook, Publisher, and OneNote. It also includes a set of web-enabled tools such as Microsoft Exchange email for business, Lync web conferencing, and OneDrive online storage.

What Is Microsoft 365?

Microsoft 365, on the other hand, is an all-in-one platform that includes the Office 365 suite, Windows 10 Pro, and Enterprise Mobility + Security to offer a comprehensive experience. Combining the best features of Microsoft’s cutting-edge software on a single platform, Microsoft 365 is an intelligent, innovative, and secure enterprise solution that has everything your business needs to stay creative, productive, and empowered.

Office 365 is great to start with, offering a bundle of cloud services that help improve enterprise productivity. But Microsoft 365 takes you a step further by helping you address complex security and compliance requirements.


Features: Quick Comparison

Here’s a quick rundown of the features of Office 365 and Microsoft 365:

  • Remote Access: One of the most significant advantages of Office 365 is that users can efficiently work from anywhere and on any device—you just need Internet access to use Office 365. Microsoft 365 is also a cloud-based platform. That means your team can work with productivity apps and tools efficiently from anywhere and on any device with an Internet connection.
  • Collaboration: Since teamwork is such an essential part of any business operation, you’re sure to love Office 365’s support for real-time collaboration. With its co-authoring support, Office 365 allows multiple users to work simultaneously on the same version of a document, presentation, or spreadsheet.


Since Microsoft 365 already includes Office 365, it also introduces the collaboration features of Microsoft Teams, OneDrive, and SharePoint. This means your teams can collaborate seamlessly with custom-tailored solutions.

While using Office 365 is a good idea at the basic level, Microsoft 365 offers added collaboration functionalities for improved teamwork and content sharing.

  • Security: Depending on the type of plan you’ve chosen, Office 365 offers a gamut of built-in security features, such as Data Loss Prevention, Encrypted Email, Advanced Threat Analytics, Mobile Device Management, Multi-Factor Authentication, Threat Management, and Exchange Online Protection. Office 365 keeps your business-critical data highly secure around the clock.


However, Microsoft 365 steals the show again with enhanced security features that include the advanced data protection functionality of Office 365 plus Enterprise Mobility & Security.

Enterprise Mobility +Security (EMS) is a key feature of Microsoft 365 giving admins:

  • Control over access to the Microsoft cloud apps with identity-driven security.
  • The ability to manage mobile devices and apps to maintain enterprise level security (This is very important nowadays with the ‘Bring Your Own Device’ environments)
  • The ability to discover, classify and monitor sensitive data across devices, services and on-premise data centers.
  • Automatic Updates: Gone are the days when your IT staff had to access each computer system or mobile device separately to uninstall older versions and install the new ones. Both Office 365 and Microsoft 365 are now available as subscription plans that already include automatic upgrade and patches to the latest version at no additional cost.
