Quick start script

# New-CsTenantNetworkSubnet — quick start (serv365.ai)
# 1. Connect (app-only shown; interactive: omit the certificate parameters)
Connect-MicrosoftTeams -CertificateThumbprint $thumb -ApplicationId $appId -TenantId $tenantId

# 2. Capture the current state first — you cannot roll back what you never recorded
$before = Get-CsTenantNetworkSubnet
$before | Format-List

# 3. Make the change (dry run first)
New-CsTenantNetworkSubnet -Identity <String> -MaskBits <Int32> -SubnetID <String> -WhatIf
New-CsTenantNetworkSubnet -Identity <String> -MaskBits <Int32> -SubnetID <String>

# 4. Verify and diff
$after = Get-CsTenantNetworkSubnet
Compare-Object ($before | Out-String) ($after | Out-String)
