Using Microsoft.Graph PowerShell to Search in Microsoft 365

There is a Microsoft.Graph PowerShell module provided by Microsoft which simplifies usage of Microsoft Graph API. Below is how to authenticate to MS Graph and how to search within SharePoint and Teams Microsoft 365 content using Microsoft.Graph PowerShell module.


Interactive authentication code sample:

# Prerequisites
Get-Module Microsoft.Graph.Authentication -ListAvailable 
Get-Module Microsoft.Graph.Search -ListAvailable 

# Interactive Authentication
$clientid = '31359c7f-bd7e-475c-86db-fdb8c937548e'
$clientid = 'd82858e0-ed99-424f-a00f-cef64125e49c'
$TenantId = '7ddc7314-9f01-45d5-b012-71665bb1c544'
Connect-MgGraph -ClientId $clientid -TenantId $TenantId

For daemon app authentication we need a certificate configured in Azure App and installed on the user machine. Daemon app authentication code sample (please specify your tenant id, app (client) id and certificate thumbprint:

# App Authentication
$TenantId = ""
$clientID = ""
$certThumbprint = ""
Connect-MgGraph -ClientId $clientid -TenantId $TenantId -CertificateThumbprint $certThumbprint

Search with Microsoft.Graph

# Search
$params = @{
	requests = @(
			entityTypes = @(
			query = @{
				queryString = "test*"
			from = 0
			size = 50
			fields = @(
                        region = "NAM"

$res = Invoke-MgQuerySearch -Body $params

Note: when you are calling MS Graph Search API authenticated as user – you need to remove “region” parameter.
