Just select Raise your hand button in the meeting controls. Everyone in the meeting will see that you've got your hand up. Meeting presenters will also receive a notification that your hand is raised, and they can lower your hand once you've had a chance to talk. Select Show participants to see a list of everyone in attendance. Anyone who's raised their hand will have an icon next to their name. When multiple people raise their hands, they'll be listed in the order in which they raised them. Note: This feature isn't available in one-on-one calls. Reference Page Entry Microsoft.
