Configure Microsoft Graph PowerShell for Easy365Manager Delegation

Microsoft Graph PowerShell - configure consent for Easy365Manager.

If you want to delegate administration of Office 365 to non-Global-Admins, you need to delegate Admin or User Consent to Microsoft Graph PowerShell for the following scopes:

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

If you have not configured Consent for your own global admin account, you can set up Admin Consent by running the following command:

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

This will open an Oauth2 authentication dialog where you must click “Consent on behalf of your organization”. This is also referred to as Admin Consent and will allow your non-global admins to use Microsoft Graph PowerShell (they still need proper Azure roles to manage resources):

Consent to Microsoft Graph PowerShell with Easy365Manager

Configure Admin and User Consent With PowerShell

If your global admin account has already been granted Consent, you’ll not get the option to grant the Admin Consent (read this article to understand why).

In that case, you can run the below script to configure the necessary Microsoft Graph PowerShell Admin or User Consent.

The script preserves any existing Admin Consent already configured on Microsoft Graph PowerShell.

However, if you select option 3 (“Remove all Admin Consent from Microsoft Graph PowerShell”), then all Admin Consent is removed (User Consent is not modified).

You can also use the script to grant User Consent to individual users for improved security.

Remember that admin consent does not grant any resource permissions to users. You still need to delegate the proper Azure roles to your admins:

  • User Administrator role
  • License Administrator role
  • Exchange Recipient Administrator role

Refer to the Easy365Manager documentation for more information.

# 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.
# Feel free to modify the script but include the following line:
# Easy365Manager - The Office 365 Management Tool for Active Directory: https://easy365manager.com
# Feel free to publish the script (with any modifications) but link credits to the following page:

After running the script and connecting to your tenant you will have the following options:

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.
