Hi @IBN ,
My users are not able to see calendar or schedule a meeting on Teams, We use exchange 2016 ( on-premise - installed on a VMware).
Was it working before?
Generally, in order for calendar access in Teams to work for on-prem mailboxes, Teams needs access to your Exchange on-prem organization for both Autodiscover and EWS. Please go through the prerequisites mentioned in the following blog and check if your environment have been correctly set up:
