Carol,
I see your predicament, but there are two things you can do to eliminate your concern.
- Limit participant access to "Read-only" from the whiteboard app.
- It works much smoother if you do not use the whiteboard app within teams and instead open the app outside of teams.
- Participants can only view the whiteboard and cannot do anything to the whiteboard
- You can change individual participants ability to interact with the whiteboard when you'd like them to participate.
- Here's a video that does a decent job of explaining the features... Microsoft Whiteboard for Education - Full Feature Overview (April 2020)
- Skip to 12:54 mark to see how to limit "Read-only" access
- Share the "Whiteboard" app window similarly to how you would share a PowerPoint or PDF
- This is maybe simpler to manage, but does not allow you the control to allow any participants to interact with the whiteboard
- Some people do not realize that when you "share" you can share a single application or your desktop and therefore get nervous sharing in case something pops up they don't want the participants to see. Teams (IMO) has made this much easier to manage than other virtual meeting platforms.
- Here's a decent video on how to share specific apps in case you are not comfortable... How to Share your screen in Microsoft Teams Meeting
Please know two things; I am not a "Teams" expert by any means, however I may or may not work for the company that made this product and use these features every single day. I come from a family of teachers and have personally taught most of them how to utilize this feature with their classes. With a little practice is works very well. Best of luck.
