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. https://support.office.com/en-us/article/Create-and-add-a-signature-to-messages-8ee5d4f4-68fd-464a-a1c1-0e1c80bb27f2 Thank you, Tony September 18, 2017 at 3:35 pm #79990 Tony AntonyParticipant Found a way to do it by editting regedit https://support.microsoft.com/en-us/help/2691977/how-to-deploy-a-default-email-signature-in-outlook Author Posts You must be logged in to reply to this topic.
