Handle appointment invitations

[8sd]

Steps to reproduce

1. send invitation to nextloud
2. the app recognizes that the mail is an invitation (shows details of appointment in special form)

Expected behavior

There should be three buttons accept, tentative, and no -accept (I don't no the correct name)
After pressing accept or tentative the appointment should be shown in the designated calendar

Actual behavior

you cannot interact with the invitation

[ChristophWurst]

I'm pretty sure this is a duplicate of #160, hence I'm closing this ticket now.

Please let me know if this is different to #160 and I'll reopen.

Thanks for your report.

[8sd]

This is no duplicate, the mail is displayed properly.
I want to add the invitation to my cal.

The issue #160 only mentions the portrayal of inivations from outlook.

[ChristophWurst]

Sorry, didn't read the full detail. Re-opening.

[toxinu]

It could be very cool to have a way to add ics to Calendar app from Mail app.

[ChristophWurst]

It could be very cool to have a way to add ics to Calendar app from Mail app.

That is already supported but there seem to be cases where the mime of the ics is not detected correctly. If you have a file to reproduce the issue, please create a new ticket and share the ics with us. Thanks.

[8sd]

So I just made an invitation.

It's displayed this way:

Here is the invite (I anonymized it)
invite.tar.gz

It looks like the file was recognized but I cannot add it to a calendar…

Hi,

i thought this feature is not implemented because I never got any accept or decline buttons when I received an invitation. After I read this entry I tried to send me invites from gmail, office365 and nextcloud. But I never saw the accept button, just the attachment. Is there anything I do wrong?

[ChristophWurst]

you're right. nobody implemented this feature 🤷‍♂️

[ToeJet]

Is it being planned as a new feature?

[ChristophWurst]

planned in a sense that we want to have this but not that it's on any roadmap or that I could give an ETA

[ToeJet]

Thanks for the quick reply. Depending on the invite, it is usually listed as an attachment such as .ics. Is there a quick way that the Nextcloud Mail could use the association to launch the associated handler which would process adding it. Similar to the way file manager can open a doc with Collabra-Office. I am assuming the link just launches with the associated nextcloud app but does not have to actually understand the link. Possibly a white list for allow extensions to launch associations?

[ChristophWurst]

That would be a possibility, yes, but we don't have this mechanism right know I'm afraid.

[ghost]

Hi, thanks for the reply! I am sorry to hear, that this is not on any roadmap. Otherwise I could finally dump all those workarounds. How does a feature like this get on a roadmap?

[ChristophWurst]

How does a feature like this get on a roadmap?

Usually if someone contributes the necessary code or by customer demand

[ghost]

Okey, thanks. Lets hope the German government has the demand ;)! Unfortunately my own programming skills won't do any good here.

[Luncheon3462]

@ChristophWurst snappymail plug-in for nextcloud handles this perfectly. I’m not a coder but if the MIME is the same, and snappymail works as needed, can code be reused?

Snappymail is Rainloop fork by @the-djmaze. https://github.com/the-djmaze/snappymail

[Luncheon3462]

@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

[ChristophWurst]

@Luncheon3462 sounds good. Feel free to bring the code over to this app 👍

[Luncheon3462]

@ChristophWurst I'm sure your comment isn't meant to be snark. I don't code, but am willing to support financially. Please tell me your preferred method for bug bounty and a suggested price.

[ChristophWurst]

I can't take any bounties. If someone wants to code this we can give pointers.

If you run a business and this is important to you: https://nextcloud.com/enterprise/

[miaulalala]

We added this with #6956

[Luncheon3462]

@miaulalala does this mean that when someone uses Microsoft Office 365 to send a calendar invite to an individual using nextcloud mail, that the nextcloud user will be able to interact with that invite directly and add it to their calendar with one click?

[keunes]

Thanks @ChristophWurst @miaulalala, great to hear this is now implemented! Which Mail app version do we need to have minimally to benefit from this? I couldn't really identify the version number from the PR, and would like to be sure so that I'm on the right version before testing (and potentially creating invalid bug reports).

Try it with with 3.5.x or if you're up for prereleases, 3.6.0.

Already thumbed up your previous comment. Please stop spamming.

[Luncheon3462]

@miaulalala I'm not trying to spam. please be patient with me. Does a thumbs up emoji mean that the answer to my question is 'yes'?

[jgonsior]

@miaulalala I'm not trying to spam. please be patient with me. Does a thumbs up emoji mean that the answer to my question is 'yes'?

Nah, a thumbs up means generally "no" /s.

[Haui1112]

I have the same issue, even on Mail 3.7.2 and Snappymail 2.36.4. I'm testing Apple <> Nextcloud and Outlook <> Nextcloud calendar invites per email. Apple works oob, both ways but NC Mail an Snappymail wont let me accept invites from Outlook.

Should I open another issue or am I doing something wrong?
