Maybe its not something that google does anymore! I have the following code. 

```
mail(from: @process_action.finance_case.case_owner.user.email, to: @process_action.finance_case.case_owner.user.email, subject: "Appointment") do |format|
   format.ics {
   ical = Icalendar::Calendar.new
   e = Icalendar::Event.new
   e.start = DateTime.now.utc
   e.start.icalendar_tzid="UTC" # set timezone as "UTC"
   e.end = (DateTime.now + 1.day).utc
   e.end.icalendar_tzid="UTC"
   e.organizer "any_email@example.com"
   e.uid "MeetingRequest#{unique_value}"
   e.summary "Scrum Meeting"
   ical.add_event(e)
   ical.publish
   ical.to_ical
   render :text => ical.to_ical
  }
end

```

Have tried setting the content type to text/calendar and a few other randon changes to see if it helped. Someone suggest the 'method' should be set to REQUEST for google to recognise but not sure how or where.

Any help/pointers would be gratefully received. Or even if it would work in Outlook as that is what the client uses.

UPDATE: Not to clear above but the email is being delivered. Its google that is failing to recognise it as an event invite.
