Sample script - classic Microsoft Teams firewall PowerShell script
This sample script, which needs to run on client computers in the context of an elevated administrator account, will create a new inbound firewall rule for each user folder found in c:\users. When Teams finds this rule, it will prevent the Teams application from prompting users to create firewall rules when the users make their first call from Teams.
