Script de exemplo – script clássico do PowerShell de firewall do Microsoft Teams

• Aplica-se a:

  Microsoft Teams

Este script de exemplo, que precisa ser executado em computadores clientes no contexto de uma conta de administrador elevada, criará uma nova regra de firewall de entrada para cada pasta de usuário encontrada em c:\usuários. Quando o Teams encontrar essa regra, impedirá que o aplicativo do Teams solicite que os usuários criem regras de firewall quando os usuários fizerem a primeira chamada no Teams.
