🌐 What Is SharePoint Online?

SharePoint Online is a cloud-based collaboration and content management platform offered as part of Microsoft 365. It helps organizations store, organize, share, and manage information so teams can work together more effectively.

Unlike traditional on-premises SharePoint, SharePoint Online is fully hosted and maintained by Microsoft. This means you don’t have to worry about servers, storage, patches, or upgrades. The platform is always up to date, highly scalable, and seamlessly integrated with tools like Teams, OneDrive, Outlook, and the Power Platform.

In short, SharePoint Online enables modern collaboration—anytime, anywhere.
