Hi Bruce
According to Microsoft's current documentation, Teams Calendar now uses a New or New event button, and meeting creation is controlled by the Teams meeting toggle within the event form, rather than always showing a separate New Meeting button.
When you select New Event, check whether there is a Teams meeting toggle in the event window. If available, turn it on and save the event to create a Teams meeting.
If the Teams meeting toggle is also missing, this may indicate an account configuration, Teams policy, or Exchange Online integration issue rather than a licensing limitation. In that case, I recommend asking your organization's IT administrator to verify that both Microsoft Teams and Exchange Online services are enabled for your account and to review any Teams meeting policies assigned to you.
If you are IT administrator, you can refer to this thread: How to fix if Team meeting toggle is missing? - Microsoft Q&A
I hope this information helps.
