Access Microsoft Whiteboard through a web browser, the dedicated mobile app, or from within Microsoft Teams. The main screen, or board picker, is where you create a new board or select an existing one. To add ideas, use the available tools like templates, pens for drawing, sticky notes, text boxes, and shapes. You can also import external content directly onto the canvas. For guided sessions, use the "follow" feature to ensure all participants are viewing the same area of the board, and set a timer to keep activities focused. Interact with your team's contributions by adding reactions to notes, using stickers, or leaving comments for feedback.
