Hi New and Vann,
Lab is having problem that ST9 service is not running. Hope they can fix it but I am not sure.
So there is not much we can to for the EIM testing at this time.
Please take a look at the email below and figure out if we get see more users (400 contacts) on the so called public group. This is on a ST8.5 environment. I did not have time to try it out yet.
Give it a try
