Hi @Jan De Smet
As far as I know, the Teams calendar itself exists in Outlook. Teams meetings created for Outlook will only appear in the Teams calendar. In short, all meetings in the Teams calendar will be displayed in Outlook, but not all meetings in Outlook will be displayed in the Teams calendar. This is by design.
As an alternative, you can choose to add a tab to your channel to view. Follow these steps:
- Add a Website tab.
- Type the tab name as you need, and then paste the URL: https://outlook.live.com/calendar/view/month (if you are using office 365 account paste the link: https://outlook.office.com/calendar/view/month)
- Then just type your account and credential as its prompt. You will view the calendar under Teams.
