Block SharePoint from Microsoft Teams with Blocker for SharePoint
What many people don’t know is that a Team owner is always also the Site Collection Admin of the corresponding SharePoint site. This gives them the opportunity to use SharePoint to its full extent without your IT department being aware of it.
To prevent this, we have developed the Blocker for SharePoint: This program allows your users to continue to access the SharePoint document library. However, when a user leaves the pages intended for them, the page is greyed out by our Blocker.
Blocker for SharePoint helps you keep control of your Teams and SharePoint environment!
