adjustment for -collaboration with partcipants

Hi there,

Since I changed my ipad, i have a trouble to use whiteboard collaborations with meeting participants. I no longer give any permission to participants to edit any contents on the board while in the meeting. They can only view what contents i present them. Whenever I add participant's email to allow them to edit or input on the shared board, the message says my organization disabled collaboration from anybody outside of my organization. I don't know how I can enable collaboration with anybody to share, view, edit and input the whiteboard. Anybody can help me out for this please?
