I developed the Lync conversation extension window to Lync 2013 client that used silverlight.
I want to resize the extension windows size and set the registry key "ExtensibilityWindowSize"=dword:00000000. But the small size(dword:00000000) and medium size(dword:00000001) are same size and identity.
How can I set ExtensibilityWindowSize to small in Lync 2013 correctly?
