SharePoint - Stop users creating sites

[DalekSec]

Bit confused with this one, recently had a clear up of all sharepoint sites, as users were able to create their own. I've turned off users being able to create sites in the admin centre and in the classic settings section...

 

logged in today to see a few new sites!!! Any idea how users are creating these and how to disable? I've double checked https://learn.microsoft.com/en-us/sharepoint/manage-site-creation and i seem to have everything correctly set!

Are they Teams sites? Are users able to create Teams, or Groups? Those would both create sites I think?

[DalekSec]

They do seem to be Team sites, so guessing need to stop users creating Teams then? so this : https://techlabs.blog/categories/office-365/stop-users-from-being-able-to-create-microsoft-teams ?

Yeah, that's the stuff. We have a group called "Teams Creators" that we add people to that are allowed to create them. Works well.

Ah thank you, will run this then

Just be sure you read what’s affected carefully, this is around O365 group creation and a surprising amount of features use O365 groups in the background. We (not edu) ended up having to turn this feature back on but added a suffix to user-created O365 groups to make them manageable l
