• add a event series
• change one occurence
• see attendee status for this exception been reset to need-action and mail sent
• see responses for attendees

-> missing bit the reponse of attendees can't be added to calendar "The Accepted response has been recorded", so it doen't check, that this is a accept for an exception

also valid for thisanfuture

• add recurring event and invite jane + another user
• accept event as jane
• ensure attendee status has been updated in johns calendar
• create an exception by moving one occurrence to another time
• ensure that the attendance status has been reset to needs-action for this instance only, and that an according invitation has been sent out.
• accept the exception and ensure the calendar is now consistent for john and jane

john needs to manually accept the update because wallace doesn't work?
