Is there a Quick way via the app or windows app to turn on and off user hours?

Hello Craig,

There is no specific on and off buttons on the app but there is a shortcut that will route you to the web portal.

Go to Settings > Phone > Extension Settings

It will take you to the web portal extension settings.

Go to Settings > User Details > Settings & Permissions > User Hours > Edit

User hours are currently only configured via online portal. You can ask for a feature request to create apps that can do the Admin features with an apps here: https://ideas.ringcentral.com/
