Hi All,

Some hours ago, Microsoft has released a new Version of the Microsoft.Online.SharePoint.PowerShell Module to the PowerShell Gallery.

Microsoft.Online.SharePoint.PowerShell 16.0.23109.12000


Check what Module Version is installed and what's available from the PowerShell Gallery

Get-InstalledModule Microsoft.Online.SharePoint.PowerShell
Find-Module Microsoft.Online.SharePoint.PowerShell


Uninstall the old Module and install the new Version

Uninstall-Module Microsoft.Online.SharePoint.PowerShell

Azure AD User setting Tenant Creation

Hi All,

Since a few Days there is a new Setting in Azure AD User Settings "Tenant creation"

Per default this setting is set to "Yes". Means that a user with can create a new Azure AD Tenant.
"No" means that only users with "Global Administrator" or "Tenant Creator" Admin Role can create Azure AD Tenants.


I can't think much of a Szenario where this should be enabled. So setting this to "No" is a secure configuration.


You can have a look ath the Authorization Policy with the Graph Explorer

GET https://graph.microsoft.com/beta/policies/authorizationPolicy



You can view and change the Setting with PowerShell.

Connect-MgGraph -Scopes Policy.Read.All, Policy.ReadWrite.Authorization
Select-MgProfile -Name "beta"
Get-MgPolicyAuthorizationPolicy | fl
(Get-MgPolicyAuthorizationPolicy).DefaultUserRolePermissions
(Get-MgPolicyAuthorizationPolicy).DefaultUserRolePermissions.AdditionalProperties | fl



Allow Tenant creation for Users

#Users can create Tenants
$Param = @"
    {"allowedToCreateTenants": true}
"@
Update-MgPolicyAuthorizationPolicy -AuthorizationPolicyId "authorizationPolicy" -DefaultUserRolePermissions $Param


Disable Tenant creation for users

#Users can't create Tenants
$Param = @"
    {"allowedToCreateTenants": false}
"@
Update-MgPolicyAuthorizationPolicy -AuthorizationPolicyId "authorizationPolicy" -DefaultUserRolePermissions $Param

Deploy PowerShell 7 Script on Azure Automation

Hi All,

In this Blog Post i explain how to Create and Depoly a PowerShell 7 Runbook for Azure Automation with the AZ PowerShell Module.

#Connect to Azure
Connect-AzAccount

#Get Automation Account
Get-AzAutomationAccount


I have two Azure Automation Accounts. In this Example, we use the second one.


###############################################################################
# Create Runbook
###############################################################################
$accountName = "icewolfautomation"
$rgName = "RG_DEV"
$location = "West Europe"
$RunbookName = "DemoPS7"
$scriptContent = @'
    #Connect to Exchange with Managed Identity
    $tenant = "icewolfch.onmicrosoft.com"
    Connect-ExchangeOnline -ManagedIdentity -Organization $tenant

    #Get Accepted Domain
    Get-AcceptedDomain | Format-Table DomainName, DomainType

    #Disconnect Exchange Online
    Disconnect-ExchangeOnline -Confirm:$False
'@

Invoke-AzRestMethod -Method "PUT" -ResourceGroupName $rgName -ResourceProviderName "Microsoft.Automation" `
    -ResourceType "automationAccounts" -Name "${AccountName}/runbooks/${RunbookName}" -ApiVersion "2017-05-15-preview" `
    -Payload "{`"properties`":{`"runbookType`":`"PowerShell7`", `"logProgress`":false, `"logVerbose`":false, `"draft`":{}}, `"location`":`"${Location}`"}"

Invoke-AzRestMethod -Method "PUT" -ResourceGroupName $rgName -ResourceProviderName "Microsoft.Automation" `
    -ResourceType automationAccounts -Name "${AccountName}/runbooks/${RunbookName}/draft/content" -ApiVersion 2015-10-31 `
    -Payload "$scriptContent"



The Runbook is now visible in the Azure Portal


###############################################################################
# Publish Runbook
###############################################################################
Publish-AzAutomationRunbook -Name $RunbookName -AutomationAccountName $AccountName -ResourceGroupName $rgName



The Runbook is now published


It contains the code


I've already created Shedules for this Automation Account

###############################################################################
# Get Schedule
###############################################################################
$accountName = "icewolfautomation"
$rgName = "RG_DEV"
Get-AzAutomationSchedule -AutomationAccountName $AccountName -ResourceGroupName $rgName
Get-AzAutomationSchedule -AutomationAccountName $AccountName -ResourceGroupName $rgName -Name "Weekly"



Here are the Schedules in the Portal


###############################################################################
# Link Schedule with Runbook
###############################################################################
$accountName = "icewolfautomation"
$rgName = "RG_DEV"
$scheduleName = "Weekly"
Register-AzAutomationScheduledRunbook -AutomationAccountName $accountName `
-Name $RunbookName -ScheduleName $scheduleName -ResourceGroupName $rgName



Check in the Portal if the schedule is Linked


And finally test the Runbook



This Script is also available on my GitHub Repo

How to Manage PowerShell 5 and 7 Modules on Azure Automation

Hi All,

As you might already know, i am a big Fan of Azure Automation.

Yesterday there was a Release of "Microsoft.Graph PowerShell Module 1.17.0" and the Question of how to update the PowerShell Modules on Azure Automate arises once again.
Basically i've covered that already in a Blog Post earlyer this Year "Update Modules on Azure Automation with AZ PowerShell".

But i think i have improved the Script a little bit. And finally i explain how to Manage the PowerShell 7 Modules on Azure Automate.

#Connect to Azure
Connect-AzAccount

#Get Automation Account
Get-AzAutomationAccount



#Get Modules
$accountName = 'icewolfautomation'
$rgName = 'RG_DEV'
$ModuleName = "Microsoft.Graph"
$Modules = Get-AzAutomationModule -AutomationAccountName $accountName -ResourceGroupName $rgName | Where-Object {$_.Name -match "$ModuleName"}
$Modules



That's the same List as from the Azure Portal


#Remove Module
#For Microsoft.Graph it is important that Microsoft.Graph.Authentication is uninstalled last due to dependencys
Foreach ($Module in $Modules)
{
    If ($Module.Name -ne "Microsoft.Graph.Authentication")
    {
    $ModuleName = $Module.Name
    Write-Host "Remove ModuleName: $ModuleName"
    Remove-AzAutomationModule -AutomationAccountName $accountName -Name $ModuleName -ResourceGroupName $rgName -Confirm:$False -Force
    }
}
$ModuleName = "Microsoft.Graph.Authentication"
Write-Host "Remove ModuleName: $ModuleName"
Remove-AzAutomationModule -AutomationAccountName $accountName -Name $ModuleName -ResourceGroupName $rgName -Confirm:$False -Force


#Add Module
#For Microsoft.Graph it is important that Microsoft.Graph.Authentication is installed first due to dependencys
$ModuleName = "Microsoft.Graph.Authentication"
$moduleVersion = "1.17.0"
New-AzAutomationModule -AutomationAccountName $accountName -ResourceGroupName $rgName -Name $moduleName -ContentLinkUri "https://www.powershellgallery.com/api/v2/package/$moduleName/$moduleVersion"



The PowerShell 5 Modules have been removed.


#Add Module
#For Microsoft.Graph it is important that Microsoft.Graph.Authentication is installed first due to dependencys
$ModuleName = "Microsoft.Graph.Authentication"
$moduleVersion = "1.17.0"
New-AzAutomationModule -AutomationAccountName $accountName -ResourceGroupName $rgName -Name $moduleName -ContentLinkUri "https://www.powershellgallery.com/api/v2/package/$moduleName/$moduleVersion"

#Wait until Module is installed
Do {
    $Module = Get-AzAutomationModule -AutomationAccountName $accountName -ResourceGroupName $rgName | Where-Object {$_.Name -match "$ModuleName"}   
    Write-Host "State: $($Module.ProvisioningState) > Check again in 15 Seconds"
    Start-Sleep -Seconds 15
} until ($Module.ProvisioningState -eq "Succeeded")

#Install the Rest of the Modules
$Modules = @()
$Modules += "Microsoft.Graph.Users"
$Modules += "Microsoft.Graph.Users.Actions"
$Modules += "Microsoft.Graph.Groups"
$moduleVersion = "1.17.0"
Foreach ($ModuleName in $Modules)
{
    Write-Host "ModuleName: $ModuleName"
    New-AzAutomationModule -AutomationAccountName $accountName -ResourceGroupName $rgName -Name $moduleName -ContentLinkUri "https://www.powershellgallery.com/api/v2/package/$moduleName/$moduleVersion"
}



The Microsoft.Graph.Authentication will be installed and after the ProvisioningState is succeeded the Rest of the Modules can be installed and the dependencys will be fullfilled.


Voila - Upgrade was sucessful


In the Portal you are able to add PowerShell 7 Modules


As you can see, there is no Parameter to address PowerShell 7 Modules

$Modules += "Microsoft.Graph.Groups"

}


Here as well Microsoft.Graph.Authentication has to be sucessfully installed before the other Microsoft.Graph* Modules can be installed due to Module Dependencys.


And now all PowerShell 7 Modules on Azure Automate have been updated



By the Way. These PowerShell Commands are also available on my GitHub Repo

Microsoft Azure Active Directory MFA Number matching comes in 2023

Hi All,

Basic Authentication has been mostly disabled. And Attackers now search for new ways to compromise M365 Accounts.
If you use Microsoft Authenticator Push Notifications - good for you. There is a thing called "MFA Fatique" that Attackers use to gain access. They send so many Push Requests until a user is annoyed and clicks on "Approve".

As anounced in the Article below, the MFA Number Matching will be enabled for all M365 Tenants starting end of February 2023. This will prevent these Attacks as the User needs to know the Number from the Request to Approve the MFA Signin.

Defend your users from MFA fatigue attacks

How to use number matching in multifactor authentication (MFA) notifications - Authentication methods policy

Go to Authentication Methods in your Azure Active Directory Tenant



I have enabled Number Matching for a Group in my Tenant


That is the Request after login in to https://office.com


And this is the Screen on the Microsoft Authenticator on the Smartphone.
Please note that i have also enabled the following Settings:
  • Show Application Name in push and passwordless notifications
  • Show geographic location in push and passwordless notifications

How IAM Systems can use Exchange RecipientManagement PSSnapin

Hi All,

I have already blogged about the Exchange 2019 Recipient Managemen PowerShell that can Manage Echange Objects without an Exchange Server running.

Install and use Exchange 2019 CU12 Recipient Management PowerShell

For Identity and Access Management Systems (IAM) provisioning, management and deprovisioning based in the past on crating a Remote PowerShell to Exchange Server. How do you Address this with the new Recipient Management?

In Fact there are two Solutions:
  • You install the Recipient Management PSSnapIn on the IAM Server (Management Tools)
  • You create a Remote PowerShell to a Server that has the Recipient Management PSSnapin installed
Let's have a look into the second Option.

$Cred = Get-Credential lab\administrator


New-PSSession

#Create PSSession
$PSSession= New-PSSession LAB03 -credential $cred

#Define String for Argumentlist
$Name = "Demo96"

#Invoke Remote Command
Invoke-Command -Argumentlist $Name -Session $PSSession -ScriptBlock {
    param($SamAccountName)
    
    Write-Host "Loading PSSnapin Microsoft.Exchange.Management.PowerShell.RecipientManagement" -ForegroundColor Green
    Add-PSSnapin Microsoft.Exchange.Management.PowerShell.RecipientManagement
    Get-PSSnapin

    Write-Host "SamAccountName: $SamAccountName"

    Write-Host "Enable-RemoteMailbox"   
    Enable-RemoteMailbox -Identity "$SamAccountName" -Alias "$SamAccountName" -RemoteRoutingAddress "$SamAccountName@serveralivech.mail.onmicrosoft.com" -Shared

    Write-Host "Get-RemoteMailbox"
    Get-RemoteMailbox -Identity $SamAccountName

    Write-Host "Remove-PSSnapIn"
    Remove-PSSnapin Microsoft.Exchange.Management.PowerShell.RecipientManagement
    Get-PSSnapin
}

#Remove PSSession
Get-PSSession | Remove-PSSession


As you can see i get an Authentication Error


The Solution comes here

Enable-WSManCredSSP -Role Server -Force
Enable-WSManCredSSP -Role "Client" -DelegateComputer LAB03



Let's check the Settings with the following Command

winrm get winrm/config/client


Let's try it again

#Create PSSession
$PSSession= New-PSSession LAB03 -authentication credssp -credential $cred

#Define String for Argumentlist
$Name = "Demo96"

#Invoke Remote Command
Invoke-Command -Argumentlist $Name -Session $PSSession -ScriptBlock {
    param($SamAccountName)
    
    Write-Host "Loading PSSnapin Microsoft.Exchange.Management.PowerShell.RecipientManagement" -ForegroundColor Green
    Add-PSSnapin Microsoft.Exchange.Management.PowerShell.RecipientManagement
    Get-PSSnapin

    Write-Host "SamAccountName: $SamAccountName"

    Write-Host "Enable-RemoteMailbox"   
    Enable-RemoteMailbox -Identity "$SamAccountName" -Alias "$SamAccountName" -RemoteRoutingAddress "$SamAccountName@serveralivech.mail.onmicrosoft.com" -Shared

    Write-Host "Get-RemoteMailbox"
    Get-RemoteMailbox -Identity $SamAccountName

    Write-Host "Remove-PSSnapIn"
    Remove-PSSnapin Microsoft.Exchange.Management.PowerShell.RecipientManagement
    Get-PSSnapin
}

#Remove PSSession
Get-PSSession | Remove-PSSession



As you can see that worked perfectly


Now you have the Solutions for your IAM System to Provision and Manage Exchange Objects without Exchange Services running. This improves the overall Security Posture as less Services are Exposed to the LAN or even Internet.

Keep in Mind that this Solution only works based on Kerberos - that means both Computers (IAM and Server with Recipient Managent PSSnapin) have to be Members of an Active Directory Domain.
