Getting failure with Connect-MgGraph.

Question

Get-MgApplication_List: Line | 5 | $appList = Get-MgApplication -All | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | Authentication needed. Please call Connect-MgGraph.

Answer 1

Hello Anil Kumar Saripadi,

I understand you are getting the "Authentication needed. Please call Connect-MgGraph" error when connecting to Microsoft Graph in your Azure Automation runbook using Connect-MgGraph -Identity.

This is a known issue that arises when using newer versions of the Microsoft Graph PowerShell modules with PowerShell 7.2.

To resolve this, remove the existing Microsoft Graph modules and install version 2.25.0 as a workaround.

You can run the following PowerShell commands in Azure Cloud Shell to install version 2.25.0:

# Import Microsoft.Graph.Authentication module

$moduleName = 'Microsoft.Graph.Authentication'
$moduleVersion = '2.25.0'
New-AzAutomationModule -AutomationAccountName 'autaccname' -ResourceGroupName 'rgname' -Name $moduleName -ContentLinkUri "https://www.powershellgallery.com/api/v2/package/$moduleName/$moduleVersion" -RuntimeVersion '7.2'

# Import Microsoft.Graph.Applications module

$moduleName = 'Microsoft.Graph.Applications'
$moduleVersion = '2.25.0'
New-AzAutomationModule -AutomationAccountName 'autaccname' -ResourceGroupName 'rgname' -Name $moduleName -ContentLinkUri "https://www.powershellgallery.com/api/v2/package/$moduleName/$moduleVersion" -RuntimeVersion '7.2'

Wait until both modules show Available in the portal before testing your runbook.

Also, make sure the Automation account’s managed identity has the Application.Read.All application permission with admin consent.

After that, you can run the following script to retrieve expired or soon-to-expire app secrets:

Connect-MgGraph -Identity
$appList = Get-MgApplication -All
$results = @()

foreach ($app in $appList) {
    foreach ($secret in $app.PasswordCredentials) {
        $daysToExpire = ($secret.EndDateTime - (Get-Date)).Days
        if ($daysToExpire -lt 30) {
            $results += [PSCustomObject]@{
                AppDisplayName = $app.DisplayName
                AppId          = $app.AppId
                SecretStart    = $secret.StartDateTime
                SecretEnd      = $secret.EndDateTime
                DaysToExpire   = $daysToExpire
                Status         = if ($daysToExpire -lt 0) { "Expired" } else { "Expiring Soon" }
            }
        }
    }
}

$results | Sort-Object DaysToExpire | Format-Table -AutoSize

Hope this helps!
