Microsoft Graph PowerShell SDK

The Microsoft Graph PowerShell SDK is a collection of PowerShell modules that contain commands for calling Microsoft Graph service.


The table below contains our Microsoft Graph rollup module. This module installs all the service modules as its dependencies.

Description Module Name PowerShell Gallery Link
Microsoft Graph Microsoft.Graph Mg

For a list of modules found in this repository, see the Microsoft Graph PowerShell modules document.


PowerShell Gallery

All the modules are published on PowerShell Gallery. Installing is as simple as:

Install-Module Microsoft.Graph

If you are upgrading from our preview modules, run Install-Module with AllowClobber and Force parameters to avoid command name conflicts:

 Install-Module Microsoft.Graph -AllowClobber -Force

There is a set of samples in the samples folder to help in getting started with the library. If you have an older version of these modules installed, there are extra uninstall instructions in the InstallModule script.


  1. Authentication

    The SDK supports two types of authentication: delegated access, and app-only access.

    • Delegated access via Device Code Flow.

      Connect-MgGraph -Scopes "User.Read.All", "Group.ReadWrite.All"
    • App-only access via Client Credential with a certificate.

      The certificate will be loaded from Cert:\CurrentUser\My\ store. Ensure the certificate is present in the store before calling Connect-MgGraph.

      You can pass either -CertificateThumbprint or -CertificateName to Connect-MgGraph.

      # Using -CertificateThumbprint
      Connect-MgGraph -ClientId "YOUR_APP_ID" -TenantId "YOUR_TENANT_ID" -CertificateThumbprint "YOUR_CERT_THUMBPRINT"


      # Using -CertificateName
      Connect-MgGraph -ClientId "YOUR_APP_ID" -TenantId "YOUR_TENANT_ID" -CertificateName "YOUR_CERT_SUBJECT"
  2. List users in your tenant.

    Get-MgUser -Top 10 -Property Id, DisplayName, BusinessPhones | Format-Table Id, DisplayName, BusinessPhones
  3. Filter a user in your tenant.

    $user = Get-MgUser -Filter "displayName eq 'Megan Bowen'"
  4. Create a new app registration.

    New-MgApplication -DisplayName "ScriptedGraphPSApp" `
                      -SignInAudience "AzureADMyOrg" `
                      -Web @{ RedirectUris = "https://localhost"}
  5. Sign out of the current logged-in context i.e. app only or delegated access.


API Version

By default, the SDK uses the Microsoft Graph REST API v1.0. You can change this by using the Select-MgProfile command. This reloads all modules and only loads commands that call beta endpoint.

Select-MgProfile -Name "beta"

Troubleshooting Permission Related Errors

When working with various operations in the Graph, you may encounter an error such as "Insufficient privileges to complete the operation." For example, this particular error can occur when using the New-MgApplication command if the appropriate permissions are not granted.

If permission related errors occur and the user you authenticated with in the popup has the appropriate permissions to perform the operation try these steps.

  • You can try running Disconnect-MgGraph, then Connect-MgGraph. Then, run the code that encountered the permission issues to see if it works.
  • You can try running Connect-MgGraph -ForceRefresh. This will trigger a refresh of the access token in your cache. MSAL will only refresh the access token in your cache if it has expired (usually an hour), or if you explicitly refresh it via -ForceRefresh. Then, run the code that encountered the permission issues to see if it works.

Known Issues

  • If you attempt to run Connect-Graph from the PowerShell ISE (integrated scripting environment) the command fails with an error "Device code terminal timed-out after {X} seconds". This is a known issue and it is recommended to use a PowerShell host other than the ISE.


If you find any bugs when using the Microsoft Graph PowerShell modules, please file an issue in our GitHub issues page.
