Microsoft 365 vs Office 365: What’s the difference?

Since its rebrand, the Microsoft 365 office and cloud service combines all the functions of the Office 365 suite. Thanks to automatic conversion, not much changed for existing Office subscriptions. New customers, in turn, can choose between different Microsoft 365 subscriptions for private or business use.

Why did Office 365 become Microsoft 365?

Productivity tools like Word and Excel have a long history dating back to the 1980s. In 2010, Microsoft made a significant move by bringing together all their essential applications into one package called Office 365. As technology evolved, with advancements like cloud integration, machine learning, and artificial intelligence, Microsoft adapted. This adaptation led to the rebranding of Office 365 as Microsoft 365 in April 2020. The goal was to create a representative complete solution that includes these new features and Microsoft’s cloud services in a unified package.

For a detailed explanation of the differences between Office 365 and Microsoft 365, see our articles ‘What is Office 365?’ and ‘What is Microsoft 365?’.

The company plans to complete the full transition to Microsoft 365 in 2023. This transition includes not only the new design but also all the Office applications that were part of the Office 365 offering. This encompasses previous subscription packages, popular Microsoft apps like Word, Excel, and PowerPoint, and the Office mobile app. Additionally, Microsoft is already announcing new features, such as improved OneDrive security, enhanced real-time collaboration with the Teams app, and AI integration in Microsoft services.

The new Microsoft 365 and the former Office 365 are quite similar, with most of the familiar Office 365 features integrated into the new all-in-one solution. We’ve summarised the few remaining main differences in the table below:
