Skype For Business - Force update with existing distribution list

Hi,

I have a question for Skype For Business.

I would like to force an update, where my Response group on my client is updated (Forced).

Here is my workflow :

I create a new distribution group
Then i hide the distribution group in the AD

Then i add members inside the Dist. group.


Now i go to the skype servers webinterface. https://skype4business/cscp

I create a new Group and under "Agents" i select : Use an existing email distribution list"



How can i now force this setting out to my client, so they dont have to wait for ?! 8 hours !? for this change - and my TestWorkFlow would appear on the clients?


Hope this makes sense :)

Thank you in advice
