How is this done?
The documentation says some nonsense to this effect:
"Calendar integration can only be enabled on an individual basis, however calendar integration can be disabled for all users by removing the last calendar presence gateway from the configuration."
What is the purpose of such a complicated integration point if it's off by default, and we have to direct users to manually turn it on themselves? I could have sworn that this was easily achievable in 8.6.x, but in 9.x, it appears like Cisco crippled the administrator's ability to actually deploy this feature to end users on a large scale.
Am I missing something here?
