Install script for Source one outlook plugin during imaging

Does anyone have a working script install for Source One plugin during windows imaging? We use MDT and the script below works on an already imaged machine with Windows 10 and office 2016. When I use the script to install Source One as a MDT task it installs but the server and port information does not persist with a domain user login. I don't want to have to type it in after the user logs in for the first time. Can I set the server and port by registry gpo entry?
