Looking for the Whiteboard in Microsoft Teams?  It is the unmissable bright blue icon on the right of the SHARE page.

Click the grey TEAMS bar at the bottom of the page when in a meeting, click the Share Button (box with the up arrow in it) and look over to the right.

How I missed this for over 8 weeks astounds me but curiously the many panic searches I did while in meetings told me to look in Conversations / More… / Apps and that just ain’t true!

Hope this helps someone.
