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.
