Outlook, set 'New message' signature

Hello,

I have a script that gets user info from AD and creates a .htm file for Outlook signature. The problem now is that, I have to manually select the signature when I’m using Outlook.

How would I set the ‘New message’ signature to the one I want? I can manually set it, but I’m trying to do it through powershell.

Thank you,

Tony

Found a way to do it by editting regedit
