Automatically attach .ics files in calendar invite emails?

Nextcloud version (eg, 20.0.5): 29.0.4
Operating system and version (eg, Ubuntu 20.04): Ubuntu Server 24.04.1
Apache or nginx version (eg, Apache 2.4.25): shipped with latest NC-AIO
PHP version (eg, 7.4): shipped with latest NC-AIO

I am currently setting up Nextcloud for my family, but we have been experimenting with the Calendar and invitations. Invitations to accounts within the same instance work fine, but we can’t invite users of Google Calendar, for example. A solution would’ve been an automatically attached .ics file for the event inside the invitation email, but it’s not present. So I wanted to ask whether Nextcloud is able to generate and attach .ics files to the invitation emails automatically, or whether there is such an option. If not, whether there is a proposal for this already or whether I should maybe propose it. At least I couldn’t find anything related to this.

Is there absolutely nobody and no information?

It’s possible, and the email even contains buttons for the recipients to click to accept or decline the invitation, as well as an attached ICS file that they can import into their calendar.

Simply click on More Details for an event and then on the Attendees tab. You’ll find an input field where you can either search for existing contacts on your Nextcloud or simply type in the email addresses you want to send the invitation to. Nextcloud will then automatically send out emails like the ones described above.

For this to work, an email server must be configured in Administration Settings → Basic Settings, and the users must have an email address set up in Personal Settings → Personal Info to be able to send invitations.

The thing is, that there is actually nomattached ics file. If I send an invitation to an external person, who doesn’t have an account on my instance, they can’t accept the invite and don’t even hace the aforementioned ics fole for importing the event.

I tested it, the way I described it in my post, and there was defently an event.ics file attached. Maybe that’s a new feature in Nextcloud 30, not sure, since I rarely use that feature.

It very likely is. Nextcloud 30 just hasn’t been pushed to AIO yet.
