I am implementing an Exchange 2016 hybrid install / sync at this moment. Where I have paused is at the Minimal vs Full hybrid configuration selection. Our exchange is onprem. We are using Teams but currently don't have availability to access the calendar from Teams. That is a known issue and one that is solved by upgrading to a hybrid exchange install with our O365 environment. The owners do NOT want user mailboxes in the cloud. Not a problem. I read your article and noted that in order to allow calendars to work in Teams the only optionwas to perform the "Full Hybrid Configuration" and that a "Minimal Hybrid Configuration" does NOT have the features / functionality required for Teams to work properly.
Is that still the case?
