Only the host of an online meeting can open the Whiteboard (Whiteboard: Microsoft NetMeeting feature that opens a separate window in which online meeting participants can type text; draw shapes; copy, paste, and delete objects; and highlight or point to text and graphics.) when Microsoft Windows NetMeeting is used from within Microsoft Office.
Tip
If you want to prevent participants from changing the shared document but still allow them to draw or type simultaneously on the Whiteboard, on the Online Meeting toolbar, click Stop others from editing
