Is AutoDiscover fully functional published for the UPN-Domains? The on-premises Exchange Servers need to be published properly for the Exchange namespace configured for the ExternalUrl property of the virtual directories used by the Teams backend.
There is a 3-part mini-series on the Teams Community Blog.

The Microsoft Remote Connectivity Analyzer has a test available for Teams calendar access.
