PowerShell to Find Users Microsoft 365 Group Memberships

Now, let’s use PowerShell to retrieve the group memberships of a given user.

Prerequisites: Install AzureAD PowerShell Module

You must have the AzureAD PowerShell module. This script installs AzureAD PowerShell module if it’s installed in your system already. Make sure you are running this as an administrator!

#Check if AzureAD Module is installed
$AzureAD = (Get-Module AzureAD -ListAvailable).Name

Try {
    If ($AzureAD -eq $null) 
        Write-host "AzureAD module is unavailable! Installing AzureAd module..." -f Yellow

        #Install AzureAD Module
        Install-Module AzureAd -Allowclobber -Repository PSGallery -Force
        Write-host "AzureAD Module installed to your machine Successfully!" -f Green
    Else { 
        Write-host "AzureAD Module is already installed in this system!" -f Yellow
Catch {
    write-host -f Red "`tError:" $_.Exception.Message

Once we have the AzureAD PowerShell module installed, use this PowerShell script to find all Microsoft 365 groups where a user is a member and export the data to CSV file.

Import-Module AzureAd -ErrorAction SilentlyContinue

$UserID = "[email protected]"
$CSVFile = "C:\Temp\GroupMemberships.csv"

Try {
    #Connect to Azure AD
    Connect-AzureAD -Credential (Get-Credential) | Out-Null

    #Get the User
    $User = Get-AzureADUser -ObjectId $UserID

    #Get User's Group Memberships
    $Memberships = Get-AzureADUserMembership -ObjectId $User.ObjectId | Where-object { $_.ObjectType -eq "Group" }

    #Export group memberships to a CSV
    $Memberships | Select DisplayName, Mail, ObjectId | Export-Csv -LiteralPath $CSVFile -NoTypeInformation
Catch {
    write-host -f Red "`tError:" $_.Exception.Message

Please note, this script gets all the Microsoft 365 group memberships of a given user, doesn’t matter if he’s added as a member or owner of the group.
