Accept calendar invitation directly in the invitation email

[enoch85]

In this issue I asked for better design for the emails being sent when inviting anyone to a event. This request is about the possibility to accept the invitation directly in the email, just like you can do with Google Calendar.

Right now you are presented with this (which is pretty nasty):

I think it's a must have to be able to accept the invitation directly in the email especially when speaking of enterprise, how can we compete with e.g. Google otherwise?

This is a topic for the MAIL app. We can't even display all invitations, currently- @ChristophWurst and others (hopefully) are currently rethinking the display of the mails. See topic nextcloud/mail#160. Before this isn't done, we can't even think of connecting mail and calendar.
Maybe a moderator can move this topic to the mail app?

Edit: Fixed link to issue

[enoch85]

@joergmschulz I don't agree that this is a mail app issue. What if you are not using the mail app? This issue is about sending invitations to anyone not only people using the mail app.

Try sending an invitation to one with Google Calendar, what will they see? They will see the regular invitation with "Yes" "No" "Maybe". Haven't tried sending an invitation to someone with outlook, but I imagine it's the same. The mail app is just a client to handle the mails that you have on another server, Nextcloud is not a mail server.

[joergmschulz]

Ah, so I misunderstood your issue - because I didn’t have it yet. All invitations I have sent and tested have been successful for: Thunderbird, Outlook, Outlook on WP8.1 and Apple Mail/iCal. So, your Google doesn’t swallow the embedded invitation? Big question: is this reproducible for other Google accounts?

@joergmschulz If the reciver have Nextcloud, and using another (domainbased) email that isn't connected to a service like Google e.g. hey@example.com the only thing you the reciver will see is what I posted in my first issue. DAV must be able to somehow generate a nice invitation, or maybe it's PHP that's necesarry, idk really as I'm not a coder.

[jancborchardt]

cc @nextcloud/calendar as this is probably more relevant for the folks ;)

[georgehrke]

I'd be happy to implement the server-side logic for accepting/rejecting invitations. Although I'd appreciate help with the mail template / mail design. (cc @eppfel ;))

[jancborchardt]

@georgehrke do you have any version you like most (like from Google Calendar / Inbox, or iCloud, etc)? Then we could start building it based on that layout, and improve going forward. cc @nextcloud/designers

@enoch85 posted a screenshot in #2071

Ping

[warnerbryce]

Ping too, having the power to answer to Nextcloud' calendar invitation inside the email would be great.
This is the big last feature that miss in this calendar.

3 companies using nextcloud as a calendar server waiting for it.

I could help for testing this feature.

[georgehrke]

@warnerbryce Help developing this feature would be even more appreciated ;)

[enoch85]

@georgehrke Give me some months, I just have to learn PHP. ;)

[eppfel]

Bountysource would be another option: https://www.bountysource.com/issues/39482696-enhancement-accept-calendar-invitation-directly-in-the-invitation-email

[enoch85]

Well, let's get this started. Just posted $50.

[enoch85]

Just posted $50.

Seems like it doesn't show up :/ I'll contact BountySource and make it happen.

Btw, Hackweek... Mind looking at this issue? please :)

[warnerbryce]

Posted 50$, this enhancement is really important for me.

[eppfel]

So, for a start...

There is a SabreDav Plugin: http://sabre.io/dav/scheduling/
Based on the both RFCs:

• https://tools.ietf.org/html/rfc5546
• https://tools.ietf.org/html/rfc6638

So we have to implement this on the server and than edit the mail template, as far as I understand it @georgehrke ?

[georgehrke]

The scheduling plugin is already enabled. ;)

We need to hook into the iTip plugin that sends the email, generate some token and write it to the database, use that token to generate a couple of links for the email.
The email needs:

• Attend
• does not attend
• unsure

and we need one token per attendee

[enoch85]

Fixed the Bountsource issue so now it's $100 instead.

[warnerbryce]

Any update for this request ? It's a deal-blocking for two clients. I will increase bounty in some days so...

[georgehrke]

Any update for this request ?

it's currently planned for Nextcloud 13 and I can assure you it won't come earlier, as we don't back port features to older releases.

[enoch85]

@warnerbryce

The best options you could get to have a nice Nextcloud Server working

...is the Nextcloud VM. ;)

[warnerbryce]

@enoch85
It’s my way or the highway.

Yeah Nextcloud VM could be really the best start for a beginner and more.

[warnerbryce]

Any news about this issue ? Does everything will be in the startingblocks for NC 14 ?

UP ? i hope it won't be delayed to NC 15

[warnerbryce]

Hello @georgehrke and @jospoortvliet

We have no news about this, does it will be ready for NC 14 ?

[georgehrke]

@warnerbryce I will look into this in the next couple of days, don't worry 😉

[MorrisJobke]

Fix is in #9942

[georgehrke]

@warnerbryce Feel free to open a follow up ticket about the enhancements you suggested in the pull-request, so they don't get lost! :)

@ChristophWurst @miaulalala @st3iny, please help get this fixed. When Office 365 sends calendar invitations, the snappymail nextcloud app by @the-djmaze handles them perfectly. They appear in the email message and can be added to a nextcloud calendar with one-click. Maybe this code that @the-djmaze mentioned will work? https://github.com/the-djmaze/snappymail/blob/fffc04499875531bd3dd626d01baaf7a86452cd3/plugins/nextcloud/js/message.js#L111-L179
