HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Office\16.0\Lync

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Lync

And folder in this location :

AppData\Roaming\Microsoft\Office\16.0\Lync 

AppData\Roaming\Skype\RootTools 

AppData\Local\Microsoft\Office\16.0\Lync 

But is doesn't work , i have also the  "Dynamic Environment Manager" but i dont know where is the Setting location saved , the most importent is the Volume that change every logout and login to station 

Can someone can help my with that , Thanks in advance
