Hi friends! 
First of all, thank you a lot for this software.
The Basics
- Nextcloud Server version (e.g., 29.x.x):
NC 32
Summary of the issue you are facing:
My issue is that i’m trying to create a calendar/event which would be added to everyone on my nextcloud instance.
From the comment in here If I go to the contacts app I should be able to add a contacts group and use it to invite to an event. The issue is that I can’t add any user of my nextcloud instance to a group.
I’m also quite confused why share a folder to a team works perfectly, but inviting a team to an event, or sharing a board from deck to a team is not possible.
A very confusing thing is the nomenclature of groups/teams. In the list of accounts as an admin is shown as groups. in the Files app is shown as teams, in calendar you can share a calendar with a team but you can’t add a team as a participant. In the contacts app is even more confusing having contact groups, teams and collectives. It seems that the collectives app allows to create collectives which can have teams inside, this is very confusing because this collectives are then available as a Team on other apps.
i’m trying to understand the current state of nextcloud, teams, circles, contacts, users, calendar, shares, collectives app.
I didn’t find until now any documentation talking about all of this. But I found many github issues and issues here in the forum.
The only thing I wished I could do right now, is to be able to invite all the users of my nextcloud or a team instance as participants of an event! I can also code in js/php but this is all so confusing that I don’t known where to start, so I decided to start here 
Configuration
