How to Configure Teams Synthetic Monitoring Policies in PowerShell Using CsTeamsSyntheticMonitorPolicy

Maintaining high-quality audio and video communications across enterprise Microsoft Teams environments requires continuous network assessment. In distributed corporate branch offices, retail store locations, and remote clinical sites, network quality degradation—caused by ISP routing changes, firewall jitter, packet loss, and asymmetric WAN routing—can severely disrupt active client calls before internal IT teams are alerted. Rather than waiting for end users to report dropped calls, enterprise administrators deploy synthetic monitoring solutions: automated test agents that generate simulated synthetic 1:1 calls, group conferences, and screen-sharing sessions to proactively measure network latency and Mean Opinion Scores (MOS).

However, automated test calls must be strictly governed to prevent synthetic test traffic from logging fictitious records in enterprise compliance archives, triggering unneeded security alerts, or polluting corporate call quality analytics with artificial telemetry. Microsoft Teams governs synthetic test accounts through the CsTeamsSyntheticMonitorPolicy cmdlets in PowerShell.

Understanding Teams Synthetic Monitoring Policy Architecture

The CsTeamsSyntheticMonitorPolicy controls how test automation bots and synthetic monitoring agents interact with the Teams calling infrastructure:

• Synthetic Telemetry Classification: Flags test calls originating from designated synthetic monitoring accounts, ensuring that automated test calls are categorized separately in the Teams Call Quality Dashboard (CQD) from real employee interactions.
• Test Call Automation Rights: Authorizes specialized service accounts to execute automated test calls on recurring schedules (e.g. initiating a 30-second audio stream every 5 minutes across WAN links to verify PSTN gateway responsiveness).
• Compliance and Recording Isolation: Ensures synthetic test streams do not trigger mandatory third-party compliance recording policies or pollute enterprise audit trails with synthetic test audio.

Connecting to Microsoft Teams PowerShell

To configure and review synthetic monitoring policies, open an elevated PowerShell console and authenticate with Microsoft Teams Administrator privileges:

# Install or update Microsoft Teams PowerShell module
Install-Module -Name MicrosoftTeams -Force -AllowClobber

# Authenticate to the corporate Teams tenant
Connect-MicrosoftTeams

Inspect existing synthetic monitoring policies configured in the tenant environment:

# Retrieve current synthetic monitoring policies
Get-CsTeamsSyntheticMonitorPolicy | Format-Table Identity, Description

By default, tenants include a Global policy where synthetic testing privileges are restricted to prevent unauthorized automated dialing.

Creating a Scoped Policy for Branch Office Monitoring Probes

To enable automated testing agents stationed at regional offices (such as dedicated network monitoring mini-PCs or virtual probe VMs), create a tailored synthetic monitoring policy:

# Create dedicated policy for Branch Office monitoring agents
New-CsTeamsSyntheticMonitorPolicy `
    -Identity "Branch-Office-Probe-Policy" `
    -Description "Authorizes automated synthetic test calls for regional network quality monitoring"

This policy object acts as the administrative authority allowing test probe accounts to execute programmatic call scripts without triggering account lockouts or spam call mitigation flags.

Creating a Policy for Core Network Datacentre Probes

For datacentre infrastructure monitoring Direct Routing Session Border Controllers (SBCs) and enterprise SIP trunks, provision a high-frequency testing policy:

# Create dedicated policy for Core Datacentre SBC testing
New-CsTeamsSyntheticMonitorPolicy `
    -Identity "Datacenter-SBC-Probe-Policy" `
    -Description "High-frequency synthetic voice probe policy for PSTN Direct Routing monitoring"

Modifying and Inspecting Policy Configurations

To inspect all configured parameters on an existing synthetic monitoring policy:

# Retrieve detailed policy attributes
Get-CsTeamsSyntheticMonitorPolicy -Identity "Branch-Office-Probe-Policy" | Format-List

To update the policy description or administrative notes dynamically:

# Update policy description
Set-CsTeamsSyntheticMonitorPolicy -Identity "Branch-Office-Probe-Policy" `
                                  -Description "Updated synthetic monitoring policy for EMEA branch locations"

Assigning Synthetic Monitoring Policies to Probe Accounts

Use the Grant-CsTeamsSyntheticMonitorPolicy cmdlet to assign policies to specific service accounts configured for network monitoring.

Assign the policy to a regional test probe account:

# Assign policy to an individual probe account
Grant-CsTeamsSyntheticMonitorPolicy -Identity "[email protected]" `
                                    -PolicyName "Branch-Office-Probe-Policy"

Assign policies across multiple regional test accounts in bulk using security group filtering:

# Retrieve all synthetic test probe accounts and assign policy
$ProbeAccounts = Get-CsOnlineUser -Filter {Department -eq "Network-Synthetic-Probes"}
$ProbeAccounts | ForEach-Object {
    Grant-CsTeamsSyntheticMonitorPolicy -Identity $_.UserPrincipalName -PolicyName "Branch-Office-Probe-Policy"
}

To remove a custom policy and revert an account back to default Global tenant inheritance:

# Revert probe account to Global policy
Grant-CsTeamsSyntheticMonitorPolicy -Identity "[email protected]" -PolicyName $Null

By implementing targeted synthetic monitoring policies with CsTeamsSyntheticMonitorPolicy, enterprise network teams proactively detect voice and video quality degradation across corporate sites while safeguarding user analytics and compliance boundaries.
