I'm running into a potential problem that my ISO has identified with our recent dive into migrating network shares to team sites in o365. I have a site that all users (I have full control as global admin) have the same level of Edit. It would've seemed to me like those users wouldn't have been able to share documents with users outside of the other site members but that does not seem to be the case. Wouldn't that be "enumerating permissions" which should only be available to someone with Full Control? Is there a workaround for this? I understand obviously that much more goes with full control than managing users, and that the sharing feature wasn't really something we had to worry about with older versions of SP, but it feels like this is circumventing this.

You can disable this in the Admin Center

  1. Go to the Admin Center (tenantname-admin.sharepoint.com)
  2. Select the Site Collection and click 'Sharing' in the ribbon
  3. Click the link 'Turn off sharing for non-owners on all sites in this site collection.'

  • Awesome! I knew that had to be there somewhere, nice and buried as usual. Thanks
