First off you have to install the AAD Preview V2 PowerShell module.
Find-Module AzureADPreview #to ensure it's in the list when doing install Install-Module AzureADPreview
Next up load the module into your PowerShell session and connect to Azure AD
Import-Module AzureADPreview $credentials = Get-Credential Connect-AzureAD -Credential $credentials
Once connected we get a copy of the template for Unified Groups, and use this to create and set new settings. If you already have settings in place for Group.Unified to for example disable group creation, you need to load and modify this setting object instead.
$policyTemplate = Get-AzureADDirectorySettingTemplate |? Id -eq 62375ab9-6b52-47ed-826b-58e47e0e304b $setting = $policyTemplate.CreateDirectorySetting() $setting["UsageGuidelinesUrl"] = "https://www.contoso.com/guidelines" $setting["ClassificationList"] = "Low,Medium,High" $setting["DefaultClassification] = "Low" $policySetting = New-AzureADDirectorySetting -DirectorySetting $setting
You might have to wait a little bit before it’s all working, but once all set, if you edit a groups’ settings, you will see a dropdown for classification, and a hyperlink to usage guidelines.
The setting is also visible on the group site.
