Our Company is about to move from Skype4B to Teams. I'm in a small testing group to check if all the features work. Some information in advance:

1. For me (and the other test users) I changed the "coexisting mode" to "Teams only"
2. In teams, the checkbox "register teams as the chat app for office" is checked. I double checked this using the corresponding registry-entry
3. The calendar is integrated in Teams and all entries are perfectly synced from outlook

When I enter a call in teams my status changes to "busy". When I stay away from the computer it changes to "away". BUT: when a meeting/appointment in my calendar starts, my status is not changed. it stays "available".

I even waited 15 minutes, nothing happens. Same is for the other testing members...

Any ideas what else to try? We're really desperate here. Thanks in advance
