Microsoft 365 - Office 365 Online


Microsoft Office Online allows for users to create, collaborate and share documents, spreadsheets, and presentations online. Office Online files are stored and shared via OneDrive, accessible either online (using a browser) or as a desktop application. Although limited in ways (see differences for each application below), Office Online allows for functionality not available in the desktop applications, including:

  • Work on documents directly in browser (with diverse browser support)
  • Autosave functionality 
  • Easy file sharing and collaboration
  • Tight integration with Microsoft 365 desktop applications

Visio for the web

Visio for the web is a new way to view, edit, and share Visio diagrams in a web browser. Start with a basic diagram to express common ideas, such as depicting a plan, making a proposal, or describing a sequence of steps in a process. It's simple to create first-class diagrams with commonly-used diagram types and rich shape sets. To collaborate with team members and stakeholders, you can share the diagram with others.
