Currently, Microsoft Teams does not support a function that allows participants to forcibly end or restore another user’s screen sharing session.

🔍 What Happens During Screen Sharing:

• If a participant starts sharing their screen, the previous presenter’s screen sharing automatically stops.
• However, there is no option to revert to the previous shared screen unless the original presenter manually shares again.
• Participants are view-only during screen sharing and cannot control or interact with the presenter’s screen.

This is a known limitation of Teams’ current design. We appreciate your understanding and recommend coordinating screen sharing transitions verbally during meetings to avoid interruptions.
