"Automatically", no.
But automatically after clicking a button to "import event to Proton Calendar" - YES! 😃

good yes and no, will be easier for us yes but that mean proton analysed our mail so not good for privacy

this should have been included by default

Any update on this? It's pretty painful to have to download the invite.ics, open proton calendar, click the settings icon (which navigates to an entirely different page than the calendar), click "Import from .ics", find the .ics in my file explorer and drag it in, and click ok.

That's a 6 step process that should be 1 step: A link on the email "Import calendar event to Proton Calendar"

I would love this feature as it would save me a TON of time and friction.

This isn't foolish at all. This is the standard for an external facing email provider that you expect to use in any professional capacity. Gmail, outlook, yahoo, and so on all do this. The accountability for ics spam getting through falls on the email provider, not me. Either figure it out, or stop trying to replace Google suite. In other words, this is a must. I purchased visionary just to access the calendar whenever it was coming out in beta. This issue is the primary reason I could not make the switch. In short, I live through my calendar and glance-read many of my emails. I cannot afford to go through each individual email, accept, deny, etc. My calendar is my personal assistant, and I need all invites to propagate there. This is the case for millions of working professions in the US alone, especially those using Gmail and Google Calendar. Fix this, and I guarantee that your retention for Proton Calendar will go way up. Professionals looking to get away from Google give it one look, see it doesn't fit there needs, and move on (no feedback). This is a major pain that is flying under the radar.

This is foolish, scam ICS is sent out and you want to add it to your calendar and automatically tell the scammer your email address is valid so that you get even more spam ??
Please rethink this idea so that it only applies to people in your contact list and all others go to spam.

Is there a way to ask Proton Mail Product Manager to check the other repeated requests about this topic, sum up all the votes and start coding this feature? In total we already have more than 37 votes!

It is annoying to download the ics file, then import it from the calendar app. Every time, for all invitations.

This would be an excellent addition

Please vote for https://protonmail.uservoice.com/forums/932842-proton-calendar/suggestions/43080603-import-ics-invite instead as it has more votes. Thanks!

As described in the title, it would be great to automatically import an event attached to a mail (.ics) to Proton Calendar without having to download and manually import it.
Moreover, I would like to automatically answer to the invite.
