What Is Microsoft 365?
Microsoft 365 is a subscription-based productivity service that combines familiar Microsoft Office apps with cloud storage, collaboration tools, and security features. Unlike older Microsoft Office packages, it is always updated and connected.
In simple terms, Microsoft 365 includes Word, Excel, PowerPoint, Outlook, OneDrive, and Teams. However, it also adds intelligent services that help people work better together. Therefore, it is far more than a basic Microsoft Office bundle.
Many UK users still call it Office 365, and that is understandable. Microsoft renamed Office 365 to Microsoft 365 to reflect its wider purpose. As a result, searches like “what is Microsoft package” or “what is Microsoft Office 365” usually lead to the same product today.
Microsoft 365 has become a staple for UK businesses, students, and professionals—but many people still ask the same question: what exactly is Microsoft 365, and how is it different from Office 365 or MS Office 365? If you’ve searched for Microsoft Office, Microsoft 365, or even Microsoft Office (yes, that typo is more common than you think), you’re not alone.
In this complete UK guide for 2026, we break down everything you need to know about Microsoft 365, from what’s included in the subscription to how it compares with the classic Microsoft Office suite. Whether you’re a small business owner, remote worker, student, or enterprise user, understanding Office 365 vs Microsoft 365 can help you choose the right tools, save money, and work smarter in today’s cloud-driven world.
Can You Use Microsoft 365 Offline?
Yes, Microsoft 365 does support offline 365 use. Once installed, desktop apps like Word and Excel work without an internet connection. However, cloud features such as OneDrive syncing and Teams meetings require online access.
For example, a UK student can write coursework on a train with no Wi-Fi. Later, when connected, the work syncs automatically. This balance makes 365 office practical for everyday life.
