Owners of a Teams Site are Owners of related SPO Site, how do I prevent this ?

[Alice_Hume]

Hi and apologies if this has been asked before ( I have searched !).

Our MS Teams site(s) started with the Business Unit Lead (important person) as the Owner and that was fine they have full permission everywhere inc the related SPO Site, but now this 'role' is being passed to the Business Unit Admin (not quite such an important person) .

My concern is that the MS Teams Owners Group become the Site Owners of the connected SPO site which means they can administer every aspect of the SPO Site.  Is there a way I can remove this group as the SPO Site Owner and replace it with another Group of my choice ?  I don't appear to be able to do that in SPO.

Hi @Alice_Hume ,

Go to the SharePoint site owners group in the SharePoint site and make a note of the name of the Security group that is in there <Group Name> Owners .

Add that same group into the SharePoint Members group.

Remove that group from the Owners.

Add your own group or person in.

Thanks Andrew, I'll test that out.

Just stumbled on this too.... :

https://[Tenant].sharepoint.com/sites/[my site]/_layouts/15/permsetup.aspx

wonder if that would do it.

Hi @Alice_Hume ,

That screen would swap out the owners group but it wouldn't do the other steps I mentioned.
