O365 / Skype for Business Credentials

I install O365 ProPlus locally on a Windows Desktop and start Skype for Business, I am prompted for my credentials, which I enter.

I then go to Skype4B options and select to start Skype at every Windows logon. Next time I logon I do not have to enter my credentials, they are stored somewhere in my user profile. I know this, as if I delete my local profile, I am prompted again for my creds.

So using UEM on a non-persistent desktop, I want to replicate this behaviour. How do I find out exactly what I need to export from my AppData folder? (We do not use roaming Profiles).

Thanks
