Teams Meeting being joined by an unknown user every time

Super Contributor

Hello Teams Community,


Please I need your help on this.


A test meeting was done during our video conferencing Teams Meeting. A Cisco Telepresence Systems was used to join the Video Conferencing Teams Meeting with a VTC Id as shown here


But suddenly an Unknow User (T) also joined the meeting as shown here.


So we would like to know why the Unknown user joined the meeting.

It seems like your Meeting policy is set to allow anonymous people to join a meeting. Set the "Let anonymous people join a meeting" to Off. > Meetings > Meeting policies > find your policy (usually Global), under Participant & guests set this "Let anonymous people join a meeting" to Off.
