In this article, we will explore Microsoft 365 in depth, uncover its features, and explain how it fits into your digital strategy.
What Is Microsoft 365? A Simple Yet Powerful Definition
At its core, Microsoft 365 is a subscription-based service that bundles together Microsoft’s most powerful tools for work and productivity. These include legacy applications like Word, Excel, PowerPoint, and Outlook, but also extend to modern tools like Teams for video conferencing and collaboration, OneDrive for cloud storage, and Exchange for professional email hosting.

With automatic updates and seamless integration across apps, users can rely on a unified platform that always stays current.
Evolution from Office 365 to Microsoft 365
To truly understand what is Microsoft 365, it’s helpful to look at its evolution. Initially, Microsoft introduced Office 365 in 2011 as a cloud subscription model for Office apps.
