Canvas displays an error message when I attempt to access Zoom in a course.
An error will display in Canvas if the user initiating the action does not yet have a Zoom account.
To create your Zoom account, please log into wsu.zoom.us and select "sign in". Once you have authenticated, your Zoom account will be provisioned.
With the account now created, you may return to Canvas to access Zoom.
Alternatively If Zoom is not loading or showing a gray/blank screen, please see Canvas Integration Not Loading.
