Is something missing?

I am running with the above configuration with out-of-the-box source (I have not done any code changes to server)

However server did not expand the group and did not create for 'eteffl'

The automatic group expansion feature is only available in the newest server releases. Use the tags/release/CalendarServer-6.0 release and make sure the GroupAttendees item in the plist is enabled.

I also tried to set 'EXPAND = 1' on event as seen below but it did not
help.

I have no idea what the EXPAND property is - neither does the server.
