Update Global Microsoft 365 Group Settings

Summary

Managing Microsoft 365 Group settings is crucial for maintaining a compliant and secure environment.PowerShell and Microsoft Graph can be used to configure various group settings, including naming policies, guest access, and more.

As a regular user of PnP PowerShell, I wanted to replicate the Microsoft Entra cmdlets for configuring group settings using PnP PowerShell.

Prerequisites

• PnP PowerShell https://pnp.github.io/powershell/
• The user account that runs the script must have Global Admin administrator access or Entra ID Admin role.

• PnP PowerShell
