Email gets deleted after responding to invitation
This has happened to me a couple of times now. Essentially, if I respond to an email from Apple's Mail app which gives me the choice 'accept', 'maybe', or 'decline', the email gets deleted and, more importantly, the event does not appear in iCal/Calendar. This is not the first message about this problem (see Macbook Mail app, Email disapears after c… - Apple Community, Macbook Mail app, Email disapears after c… - Apple Community); however, that issue was pushed to Apple support because the person who posted the question didn't know how to invite people to an event.
The fact is that this has happened to me before and, although I didn't know the email was sent to the trash (I genuinely thought the email had disappeared on its way to the Calendar app through some bug), like the previous poster said, the email should not be deleted or, at the very least, the event should appear in Calendar with the email copied into the Notes or as an attachment to the event.
I guess I'm asking why the event is not appearing in the calendar app, particularly if the email is being moved to the bin after responding.
