Integration with WebEx is enabled by default at the administration level. So long as this feature is not disabled by your GroupWise Administrator and you have a WebEx account, you can schedule Teams meetings with GroupWise. When WebEx Integration is enabled, you can schedule, send, modify, or cancel WebEx meeting appointments from GroupWise. If so enabled by your administrator, you can disable WebEx Integration in your GroupWise Client by navigating to Tools > Options > Environment > General tab.
WebEx meetings scheduled in GroupWise can only be managed from the GroupWise Client. If you have the WebEx app installed on your device, you will not see these appointments on the WebEx calendar. However, all WebEx appointments that you schedule in GroupWise have a meeting link when you open the appointment in GroupWise; when you click this link, Microsoft gives you a choice to open the meeting in WebEx via your browser or from the WebEx app.
The first time that you schedule an appointment in GroupWise using WebEx, you will need to log in to your WebEx account to associate it with your GroupWise account. Any appointments thereafter, will automatically sync the two accounts for WebEx meetings. If at anytime you log out of or become logged out of WebEx on the same device where you are accessing the GroupWise Client, you will be prompted again to log in to your WebEx account the next time you schedule a WebEx appointment from GroupWise on that device.
