Is it possible to disable subsite creation in a modern team site?
You can turn this off for the entire tenant in the SP admin center. Settings>Subsite Creation.
Here's the text from the setting:
Control whether site owners can create a subsite in a site that includes an Office 365 group. This setting determines whether the option to create a subsite is available on the Site contents page when users click New.
The permission policies are not available anymore in Modern Team Sites. The options you have on the site settings page changed for Modern Team Sites. I would prefer an option within the Admin Center to control this option. Just like the option you have to show or hide the "Create site" option.
Any other options to prevent users from creating subsites and a way for limiting the Site Template selection?
Side note: i think it is really strange from a governance perpective that a "Joe User" that created a regular Group or Teamsite gets Site Collection administration permissions...
Many administrative pages are hidden for modern team sites, but they are accessible anyway using the direct URL.
For permissions, for example, you have to go to https://<tenant>.sharepoint.com/sites/<site>/_layouts/15/user.aspx
I am not interested in these administrative pages through hidden url's. Just plain and simple control over what users can do in a site. It seems strange that MS has a strategy of hiding stuff from users to keep it simple. Then it is rather strange to see that these users become Site Collection Owners and can created a Record Center below a simple team site...
Questions still stands:
1. Can we prevent users from creating subsites through a tenant level setting. For example the SharePoint Admin Center or PowerShell command
2. If the above functionality is not available, can we change the available site templates in the subsite creation dialog. Normally this can be configured for each site collection, preferably we want to configure this on the tenant level.
It could be strange, but it is true...
I found the thread in which we discussed such things: https://techcommunity.microsoft.com/t5/SharePoint/Site-Collection-Admin-in-Modern-Team-Sites/m-p/35267/highlight/true#M3178
In particular look at this words: "...the difference with our modern UX and O365 groups is that we are doing more and more work to hide the paths that are most likely to cause pain like this."
- And just remeber that the backend is still SharePoint Online and those options have been there for ages...and they are required in classic SPO sites.
- Yeap, you know another piece of basic functionality that should be in modern team sites and not hidden
What's worst is that hiding functionalities in Office 365 seems an intentional strategy by MS ...
In fact it appears to me that, in order to prevent unexperienced users froom shooting in their feet, they are basically pushing out a "three administrative configuration levels" model: visible pages, hidden pages, powershell.
I have not been able to find the the relevant thread, but I remember that, a couple of months ago, an MS representative explicitly stated such strategy in this forum.
