How to apply signature templete on New Outlook by Intune

Hello neerajpunjab

 Test the signature deployment on a small group first

First:
•    Verify you're using the latest version of the new Outlook
•    Ensure your Microsoft 365 tenant is configured for the new Outlook client
•    Check that the devices have the necessary update and configuration permissions
To apply signature templates to the new Outlook client via Intune, you'll need to follow a few specific steps:

Microsoft 365 Admin Center Approach:
1.    Go to the Microsoft 365 Admin Center
2.    Navigate to Settings > Org Settings > Email Signatures
3.    Create your organization-wide signature template
4.    This method works for both classic and new Outlook clients
Intune Configuration:
•    Use Microsoft Intune to create an Administrative Template policy
•    Target the policy to devices running the new Outlook
Key settings to configure:
•    Use the Office Cloud Policy Service
•    Create a configuration profile for Outlook email signatures
•    Ensure the policy is assigned to the correct user or device groups
PowerShell and Registry Method:
Create a PowerShell script or registry configuration
Set the following registry key:
CopyHKCU\Software\Microsoft\Office\16.0\Outlook\Preferences\EmailSignature
Use Intune to deploy this configuration
Recommended Troubleshooting Steps:
•    Confirm the new Outlook is fully integrated with your Microsoft 365 environment
•    Verify user licenses and permission levels
•    Check Intune logs for any deployment issues
