Create users and groups that cannot see & communicate with each other in SharePoint?

[Michael_Zyx]

I have attached a diagram of the exact functionality we are looking for in SharePoint.

Please take a look and tell me if its possible.

Thank you!

Hi @Michael_Zyx ,

Permissions is fine. Just permission the sites as per your requirements. 

Seeing and communicating is on a different level though. I haven't seen this done and suspect you would need to look at Azure AD for this, if it were possible.
