Can a Meeting Co-organiser add additional co-organisers to a meeting

Hi SarahLilley,

you can find a role description of the Co-Organizer in the official Microsoft documentation:

Roles in a Teams meeting - Microsoft Support

Here you can find the more general information that a co-organizer can change the role of a user.

To clarify it for myself as well, I've setup a meeting in my lab environment and added a user as co-organizer to the meeting. The co-organizer can add new co-organizer in my tests. The only restriction is that the user must be invited to the meeting by the organizer first and directly.

When you as a co-organizer forward the meeting to another user, you cannot add them as co-organizer. 

Best regards,

Thorsten
