No invitation mails are sent to external contacts

Fobhep commented 1 year ago

Steps to reproduce

Setup outgoing mail account with admin user in Nextcloud. Test mail sending successfully
Login with non-admin user. Create an event and invite somebody externally

Expected behavior

The external mail address should receive an invitation to the event.

Actual behaviour

No mail is sent, regardless whether I set up the event on the web-gui or via a caldav client, eg on my phone.

Additional info

No relevant log information at all. At least none that looks anyhow suspicious to me. I will gladly provide logs if helpful.

Your NC instance is able to send emails in general?

Can you export and post one such calendar invite here? You can do so by clicking on the event and using the three dot menu to download the ICS.

Can you also look into your logs for loglines with message "Unable to deliver message to" ?

larsneo commented 1 year ago

same problem here (nc 27.1.2, calendar 4.5.2)

nextcloud is able to send emails in general
mailadress of organizer and participant is set as expected in ics VEVENT ORGANIZER;CN=vorname nachname:mailto:vorname.nachname@domain.com ATTENDEE;CN=vorname nachname;CUTYPE=INDIVIDUAL;PARTSTAT=NEEDS-ACTION;ROLE=REQ- PARTICIPANT;RSVP=TRUE;LANGUAGE=de_DE:mailto:vorname.nachname@domain.com
there's nothing related to messages in the log and no open job in the corresponding db-table

miaulalala commented 1 year ago

Aight, I guess we're gonna need some logging in the iMIP Plugin to see where exactly the mail fails. Everything else is fine I assume? I.e . calendar events are saved and you're able to update / delete them?

nursoda commented 11 months ago

Same applies for invitations RECEIVED from 3rd party contacts: Once I change my attendance status, a messages should be sent to the organizer (or all attendees?) to inform his/their calendar that I will/not attend.

Also experiencing this problem. And found this in my logs:

iTip message said the change was significant but comparison did not detect any updated VEvents

Am wondering if this means that the issue is related to https://github.com/nextcloud/server/issues/23927

not really, as that issue was a problem with an x- property.

The error message comes from https://github.com/nextcloud/server/blob/aa5f037af71c915424c6dcfd5ad2dc82797dc0d6/apps/dav/lib/CalDAV/Schedule/IMipPlugin.php#L137

Confirming as well. Using Nextcloud Hub 7 (28.0.5), Calendar 4.7.15. I checked the logs, but did not see anything that might point into the direction of what goes wrong.

janvlug commented 2 months ago

I figured out that the problem for me was that I had not set the Email server in Administration settings > Basic settings > Email server

After adding an SMTP account there, invites were sent out.
