I am missing the meeting / calendara button in teams, I have checked the policies and cannot find the problem
@Juan Carlos González Martín yes I do
I was in the same situation and apparently your Exchange OnPrem needs to be in Hybrid mode for Teams to work correctly
After I configured my Exchange OnPrem for Hybrid with EXO, Teams started showing Calendar button
Is there any cost to run Exchange onprem in Hybrid Mode?
I have an M365 E3 subscription.
