Only Paid Participants Can Be Hosts Error - Zoom
This error occurs when trying to add a host or alternate host and their UW Oshkosh credentials for our Zoom instance have expired.
To fix this error the person you are trying to add should:
Open an incognito or private window in their web browser
Navigate to https://wisconsin-edu.zoom.us
Click on Sign in
Select our UW institution (UW-Oshkosh)
Login using their UW-Oshkosh email username and password.
This will reauthenticate them in our Zoom instance and they will have a paid license.
