NC should send out RSVPs to calendar invites from an own mailbox and receive the responses directly

[dphi]

Scheduling appointments via NC using the calendar app is not possible today because responses are not reaching NC. This situation will slightly improve in NC14 with the RSVPs buttons in the invitation but this won't work for participants relying on iMip, esp. Exchange+Outlook users.

If NC would send out invitations and receive the responses directly it could manage the participants RSVP status in-depended of external SMTP and CalDav clients.

What should be considered is how RSVPs with comments can be handled best. These should reach CalDav (if possible?) and the mailbox of the inviting user.

GitMate.io thinks possibly related issues are #8423 (thunderbird/lightning not sending calendar notifications), #2338 (Accept calendar invitation directly in the invitation email ), #10488 (Support invite-rsvp-checkstatus calendar workflow with exchange), #3830 (No calendar invitation send for event in shared calendars ), and #2855 (Invitation send to attendees upon calendar import (also for past events)).

+1 I second this. At the moment, using NC with Mac/IOS PIMs is very cool for the most part, but when it comes to invitations, it's really a mess. I'm not sure who's fault it is (and I suppose, in doubt, it's Apple's fault), but this idea came to my mind too. NC could monitor an IMAP account and process incoming replies. I'm available to help coding and testing this thoroughly.

Duplicate of #5080

@georgehrke This does not seem to be a duplicate of #5080. In the mentioned ticket the issue is about invitations being sent out by a certain e-mail adress. This issue here is about Nextcloud not handling responses from participants if they are coming back through e-mail.

First of all I appreciate everybodys work on this, and the calendar app is awesome. It's not that intuitive that the Calendar app is able to send out invitations but does not care about responses back. Through the way this feature works in Google Calendar and Outlook/Exchange, one assumes that the calendar app takes care of responses by itself.
Also currently there does not seem to be a way to even manually get the information from response e-mails ("Accepted: [Event Title]" and attached .ics file) from participants back to the server.

So the desired result would be, that Nextcloud server handles the responses via email and refreshes the participants state (accepted / declined) according to the behaviour of similar services like Exchange or Google Calendar. It would be great if you could open the issue again.

Is there any way one can help to advance this issue without being able to develop?

Why is this ticket ignored so heavily?

Like @rinurinu pointed out almost 2 years ago, this ticket is NOT a duplicate of #5080. @georgehrke could you please reevaluate this issue? This is a real thing ppl would like to use.

Currently I have to explain to every single person I send an invitation to, that they need to use the links instead of the dedicated buttons they are used to by their mail client...
