How to set everything to silent except the alarm clock [7.1.1 Nougat] Does anybody  know how to set everything to silent except the alarm clock? In priority only, and alarms only mode, both calendar reminders and alarm clock notifications make the phone vibrate. If I set it to full silent both are silenced.

Currently I'm using the business calendar app

I'd like to configure the calendar to only notificate in priority mode and not in alarms only mode.

(The problem I'm having is full day calendar appointments make my phone vibrate at midnight.)
You can try to achieve this by automation. I prefer MacroDroid being easy to learn and free

I don't have Nougat , so can't test it. I also recall  reading that dnd mode is behaviour is different compared to Marshmallow ( and don't remember how), so this may need further tweaking based on your revert



The way I understood your need and accordingly configured macro is


You are in Priority mode ( not alarm only )
Your calendar app sends a notification which needs to be seen by not heard ( select your  calendar app in Trigger, in the macro I chose default calendar app)
