Providing access to external / guest users to Microsoft Teams and its resources is inevitable in any Organization which uses Microsoft Teams for primary means of collaboration. When more and more guest users are given access in a Team, it becomes a burden for the administrators to track who are those guest who have access to their Teams. The security reports category in the Microsoft Teams module provides detailed information on these security vulnerabilities like external user membership and ownership.The following are the list of available Teams Security Reports:

List of Teams with owner who is not a member
