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