GAM command for Google Chat

[U. V.]

Hi Ross,

I wanted to disable or Turn OFF Google Chat for specific users, Are there any commands are available to turn OFF these services for domain users? 

Basically, I don't want to change my OU structure and Google Group won't be helped to disable this service.

No, you can only do it from admin.google.com. 

While you can use OU to turn services ON/OFF, you cannot use groups to turn services off if it's already ON. 

That being said, you could disable the service at the Root OU and create two groups to turn service back ON (e.g chat-d...@yourdomain.com and chat-e...@yourdomain.com)
