This error occurs when someone with the Instructor role clicks a Zoom Student link, such as in the course menu or a content area. The only way for an instructor to access Zoom in Blackboard is to use the Zoom - Instructor link.
In the Ultra Course View, go to the Details & Actions area on the right of the course and click Books & Tools, then find Zoom - Instructor.
In the Original Course View, go to the Control Panel, click Course Tools, then find Zoom - Instructor.
If you want to test that students are able to access your Zoom sessions via Blackboard, you must first launch the Student Preview mode.
