On Webex, if you are using a Mac, you can only join one meeting at a time. If you do not officially leave your previous meeting before attempting to enter another meeting by clicking the Leave red X icon, you will receive this error message:
If this happens, follow these steps:
1. Close the current meeting window with the error message.
2. Go back into the previous Webex meeting you had exited using the link or invitation provided. If you were invited to the meeting, please check your Webex meetings calendar, email, or your Brightspace course page for that information if it was a class session. If you aren't able to find that information, you may be able to fix the issue without it. You should check your settings to see if you have accepted the Webex plug-in for Safari. The steps for how to check this are here.
3. Exit this meeting using the Leave red X icon, and then select Leave Meeting in the pop-up window.
4. Re-enter the new meeting using the link or invitation provided.
