Am I missing something or did MS take this important feature away?

On my old 920 running Windows Phone 8.1, any calendar entry I made that was marked "Busy" automatically put my phone in "quiet mode" and I never had to worry about being disturbed (except by my inner circle) when I was in a meeting.

Is this feature gone now in Windows 10 Mobile? I am running a new Lumia 950XL.

Yes, it's gone. Hopefully temporarily.

Yep, bpsmicro has nailed it. It was a feature added by Cortana in WP8.1 (i.e. WP8.1 didn't originally have it).

Sadly, it's not present in the W10M version of Cortana.

This is a major show-stopper for me (I'm in and out of lectures during the day and cannot risk having the phone ring if I forget to silence it), so I had to revert to WP8.1.

As an aside, I was surprised by how wonderful WP8.1 felt compared with W10M. When running W10M I missed the gorgeous design language of WP8.1. Sadly, Microsoft deliberately jettisoned it for a number of reasons and deliberately moved towards an iOS/Android style of UI. (Dammit, I've started on my rant again!)
