I just got my first positive result after configuring Run Once registry to call cscript command from batch file.
I am restarting my test from scratch to be sure.
Even though my roaming profiles and folder redirection seems to be working well, I notice that if/when I receive a different linked clone (since this is a floating pool) my inbox from the exchange server downloads again which could take several minutes. I am assuming that is because a local app data requirement to populate .ost file or something. I would wonder if there is a way redirect the .ost so that it syncs up elsewhere....or maybe create dedicated pool with persistent disks.
