That is correct. Mailboxes needs to be hosted in Exchange Server 2016 CU3 or later.

Hi,

We have Exchange 2019 CU7 on premises in a full hybrid configuration with O365 and for a long time the calendar was working fine for all our on premises users (windows and mac). A few days ago, after Teams update to version 1.3.00.30866, all users lost the calendar, so we also had problems with this new version.
