Disabling Site Creation from end users, will still allow them to create sharepoint sites through creating new Office 365 groups

Question

I am working on a SharePoint online tenant, and inside the SharePoint admin center site >> Setting page, i disable site creation as follow:-

So i thought that in my case only sharepoint admins (the user which i own), will be able to create new sharepoint sites.. but i have found that there are many sharepoint sites that have been created by end users (i think those got created when end users create new Office 365 groups). here is a site which got created by end users:-

so my questions are:

1. is there any relation between the ability for users to create new sharepoint sites (through creating Office 365 group) and disabling the site creation inside sharepoint admin center's setting page (as shown in my first pic) ??

2. How we can prevent end users from creating sites, even through creating office 365 groups?? is this something we can manage??

Thanks

Answer 1

First of all, the setting only hides the command and does not disable the option to create sites for users. It says so in the setting in your screenshot.

And yes, whenever a group is created in Office 365 you get a SharePoint Modern Team site. And a group is created when you create a Team, Yammer Group, Staffhub group, PowerBI workspace, and maybe more.

If you really want to disable this, you need to disable group creation for all your user. See: https://support.office.com/en-us/article/manage-who-can-create-office-365-groups-4c46c8cb-17d0-44b5-9776-005fced8e618

If that's not what you want, you could create your own governance solution or buy something of the shelve that manages group / team / site creation for you.
