When the Host clicks on "End Meeting", three options appear:
- End Meeting for All: Everybody is dismissed from the meeting and it is concluded. Such things as Chat are deleted
- Leave Meeting: The Host leaves the meeting and the others may continue.
- If the Host does NOT appoint a Host or Co-host before leaving, any participant may be selected to be Host. In such case, if the original Host returns to the meeting, he/she will automatically be reinstated as Host.
- If the Host assigns a Co-host role to a participant, this person will become Co-host after the original Host leaves the meeting. If the original Host returns to the meeting, he/she will automatically be reinstated as Host.
- If the Host assigns the role of Host to a participant, that person will immediately become the Host. The original Host becomes an ordinary participant. If he/she leaves and returns to the meeting, he/she will become Co-host and must click on "Reclaim Host" under "More" in order to be reinstated as Host:

- Cancel: The Host remains in the meeting and nothing changes
Co-Host
The Co-Host-function enables the Host to share Host rights with another user, so that the Co-host can perform management functions in the meeting, such as managing participants or starting/stopping recording.
The Host must appoint a Co-host. There is no limit to the number of Co-hosts that can be appointed.
To assign the Co-host role the Host must use the mouse to point to the name of the person in question and click on "More", followed by "Make Co-host":

The Co-host does NOT have access to the following controls, since they are only accessible as Host controls in a meeting:
- Conclude the meeting for all participants.
- Make another participant Co-host.
- Start Breakout Rooms or move participants from one Breakout Room to another (the Co-host can move between various Breakout Rooms).
- The Co-host may not start a meeting. If the Host needs others to be present in order to start a meeting, he/she may assign an alternative Host role while planning an online teaching session in Canvas.
