PowerShell 腳本範例 - 為貴校的授課者和學生建立安全組

使用此 PowerShell 腳本建立您在學校管理 Microsoft Teams 原則所需的安全組。 Teams 中 群組功能的原則指派 可讓您將原則指派給使用者群組,例如安全組。 原則指派將根據優先順序規則傳播到群組成員。 在群組中新增或移除成員時,系統會相應地更新其繼承的原則指派。

此 PowerShell 腳本會根據授權類型建立兩個安全組,一個供教職員和授課者使用,另一個供您學校的學生使用。 接著,您可以將原則指派給您所建立的安全組。 如需使用此腳本的詳細資訊,請參閱 指派原則給學校中的大型使用者群組

此文稿會執行下列動作:

  • 識別已指派教職員 SKU 的教職員和授課者、建立安全組,然後將教職員和授課者新增至群組。
  • 識別獲指派學生 SKU 的學生、建立安全組,然後將學生新增至群組。
  • 匯報 每個安全組的成員資格,以根據他們是否擁有授權來新增或移除教職員、授課者和學生。

您必須定期執行此腳本,才能讓安全組保持在最新狀態。

重要

將原則指派給群組時,請務必瞭解 優先順序規則群組指派排名 。 請務必閱讀並了解 關於群組的原則指派所需注意事項中的概念。

開始之前

下載並安裝 商務用 Skype Online PowerShell 模組,然後在出現提示時重新啟動電腦。

注意事項

Azure AD Powershell 預計於 2024 年 3 月 30 日停用。 若要深入瞭解,請閱讀 即將停用的更新

我們建議您移轉至 Microsoft Graph PowerShell,以與 Microsoft Entra ID (舊稱 Azure AD) 互動。 Microsoft Graph PowerShell 可存取所有 Microsoft Graph API,而且可在 PowerShell 7 上使用。 如需常見移轉查詢的解答,請參閱 移轉常見問題

<#
Script Name:
CreateOrUpdate_SecurityGroup_Per_LicenseType.ps1
Synopsis:
This script is designed to perform following operations:
1. Create a security group for faculty and student members based on the assigned license SKU and add the members accordingly.
2. Update the security group to add/remove teachers and students so that only users who have a valid teacher/student license are present in the group.
The output of the script is written in a log file present at location: C:\results\log.txt
