Teams Calendar not available for some users

[SimonAuty]

Hi,

We've recently rolled out Teams for all users and configured a Hybrid Exchange setup. All is good, however some users are not getting the Teams calendar in their client. 

This seems to work fine for our primary email domain, but users in secondary domains are not getting the Calendar app to show in teams. 

All users are currently on prem.

Any ideas why this is?

See if this helps.
