配置 Microsoft Graph PowerShell 进行委派

如果要将 Office 365 的管理委派给非全局管理员，则需要针对以下范围将管理员或用户同意委派给 Microsoft Graph PowerShell：

• User.ReadWrite.All
• Group.ReadWrite.All
• Domain.Read.All
• Directory.ReadWrite.All
• offline_access

如果您没有为自己的全局管理员帐户配置同意，则可以通过运行以下命令来设置管理员同意：

Connect-MgGraph -Scope "User.ReadWrite.All Group.ReadWrite.All Domain.Read.All Directory.ReadWrite.All offline_access"

这将打开 Oauth2 身份验证对话框，您必须在其中单击“代表您的组织同意”。这也称为管理员同意，将允许非全局管理员使用 Microsoft Graph PowerShell（他们仍然需要适当的 Azure 角色来管理资源）：

使用 PowerShell 配置管理员和用户同意

如果您的全局管理员帐户已获得同意，您将无法获得授予管理员同意的选项（请阅读本文以了解原因）。

在这种情况下，您可以运行以下脚本来配置必要的 Microsoft Graph PowerShell 管理员或用户同意。

该脚本保留 Microsoft Graph PowerShell 上已配置的任何现有管理员同意。

但是，如果您选择选项 3（“从 Microsoft Graph PowerShell 中删除所有管理员同意”），则所有管理员同意都会被删除（用户同意不会被修改）。

您还可以使用该脚本向各个用户授予“用户同意”，以提高安全性。

请记住，管理员同意不会向用户授予任何资源权限。您仍然需要将适当的 Azure 角色委派给管理员：

• 用户管理员角色
• 许可证管理员角色
• Exchange 收件人管理员角色

# This script creates admin consent to let Microsoft PowerShell Graph access Microsoft Graph.
# The consent includes Read/Write to Users, Groups and Directory plus Domain Read access and long lived refresh tokens.

运行脚本并连接到您的租户后，您将有以下选项：

Easy365Manager v. 1.5 uses the Microsoft Graph PowerShell SDK - the future of Office 365 management.
Before you can use the SDK, you must grant consent to the SDK to call the Microsoft Graph on your behalf.

This script allows a Global Admin to configure an Admin or User Consent, enabling non-Global-Admins to call the SDK.
The Admin/User Consent does not grant users any rights. It only enables the SDK to use users' existing rights.

If you already configured Microsoft Graph PowerShell Admin Consent, you can skip this step (press 'X').
If all Easy365Managers are Global Admins, you can skip this step (press 'X').

Only Global Admin role holders will be able to use Easy365Manager until the Admin/User Consent has been configured.
