Applies to:This message applies to Teams for Windows desktop and Teams for Mac desktop

The annotations start only after the active sharer approves the request. This capability is available exclusively in the new Microsoft Teams experience on native Windows and macOS apps.

This release also introduces a meeting option in the Participation section, allowing organizers and co-organizers to choose who can start annotations. By default, "Everyone" can access the "Start Annotation" button, but organizers and co-organizers can limit it to just the "Active Sharer", making the button visible only to the person currently sharing their screen or window.
