using MS Teams to create a video message board

Hi DaMagicOne,

Here is the Microsoft Digital WhiteBoard that can be used for Presenting. I haven't done this kind of a solution but for your requirement I can recommend a workaround solution that should be helpful.

Microsoft Digital WhiteBoard

The Workaround Solution is as follows:-

1. Create a Team of all the Members who are required to Publish the Information Round the Clock.

2. Add One Note in the Microsoft Teams Channel. Using this One Note Application all the information which needs to be published to round the clock team members can be published accordingly.

Let me know if the workaround helps 

With Regards,
