What is Get-MgReportTeamCount?

Get-MgReportTeamCount is a Microsoft Graph PowerShell cmdlet that retrieves a report on the total number of Microsoft Teams within your Microsoft 365 tenant. This cmdlet provides insights into how many teams exist and can be used to track changes over a specific period.

It allows administrators to generate reports either interactively or by directly specifying parameters for automation.

Why Use Get-MgReportTeamCount?

Admins should use Get-MgReportTeamCount because:

Usage Examples

1️⃣ Running the Cmdlet Interactively

If you run the cmdlet without parameters, it will prompt you to enter the required values.

2️⃣ Running the Cmdlet with Parameters

You can pass the required parameters directly to generate and export the report.
