🧠 How Microsoft Loop Workspaces Work
-
Built on Fluid Framework for instant sync
-
Workspace = container for Pages and Loop Components
-
Optimized for dynamic, changing work (e.g., brainstorming, agile projects)
-
Embedded across Teams chats, Outlook emails, and Word web apps
-
Designed for flexible, modular work, not strict file/document hierarchies
📒 How OneNote Notebooks Work
-
Notebook = Collection of Sections ➔ Pages ➔ Subpages
-
Structured note-taking, focused on hierarchical knowledge storage
-
Best for static or semi-structured knowledge (e.g., meeting notes, research logs)
-
Not modular: content is static per page
-
Offline-first approach: local sync on desktops and mobile devices
🏛️ How SharePoint Sites Work
-
Site = Web-based container for lists, libraries, pages
-
Optimized for document management, workflows, approvals
-
Heavy integration with Power Automate, Microsoft Lists, Office files
-
Ideal for formal team knowledge bases, intranets, business processes
-
Strict governance, metadata tagging, DLP enforcement
