To be notified if a user creates a new Team in the Microsoft Teams client, you should configure an alert policy in the Security & Compliance admin center. This is the appropriate way to set up notifications for specific activities within Microsoft 365, including the creation of new Teams. Configuring external collaboration settings, supervision policies, or eDiscovery cases would not directly address the requirement of receiving notifications for new Team creations.
To generate and view debug logs on a user's computer in Microsoft Teams, you should press the key combination Ctrl+Alt+Shift+1. This shortcut directly provides access to the debug logs needed for troubleshooting issues within the Teams desktop client on Windows.
The most appropriate role to assign, in adherence to the principle of least privilege, is the Reports Reader role. This role provides the necessary permissions to view usage reports without granting additional administrative privileges that are not needed for the task. Assigning more expansive roles like Teams Communications Administrator or Security Administrator would provide unnecessary access beyond what is required to view the reports, which violates the principle of least privilege.
To restore a deleted team in Microsoft Teams, the appropriate tool to use is the Microsoft Teams admin center. This tool allows administrators to manage and restore teams directly within the Microsoft 365 ecosystem. By navigating to the Microsoft Teams admin center, you can access the 'Teams' management section, view a list of all teams, and restore any deleted teams from there. The Teams admin center is specifically designed for managing such tasks, making it the most suitable option for restoring deleted teams.
To ensure that group membership is validated every month and that only members and guest accounts requiring access remain in the group, you should configure an Access Review. Access Reviews in Microsoft 365 allow administrators to periodically review and ensure the right users have access to the appropriate resources, making it the suitable solution for this scenario.
