You have a Microsoft 365 E5 subscription that uses Teams and contains three teams named Team1, Team2, and Team3. You need to validate the owner of each team and identify the number of guest users…

Usage reports provide aggregated data on Teams activity and adoption, but they typically do not offer a direct, easily consumable list of team owners and guest counts per individual team for specific validation.

Teams Advisor is a tool that helps organizations plan their Teams rollout, offering guidance and best practices, not a feature for managing or validating existing team properties like owners or guest lists.

In the Microsoft Teams admin center, the "Manage teams" section provides a centralized view of all teams within the organization. From this interface, an administrator can select each team to view its members, identify the team owners, and see the list of guest users, thus fulfilling both requirements to validate owners and count guest users.

The "Manage users" section focuses on individual user accounts and their associated Teams policies or settings, rather than providing a per-team view of membership including owners and guest users.
