When my Gmail account receives a .ics invite from Proton Calendar, my Google Calendar automatically shows the event, marked as still needing an RSVP. If I move the event in Proton Calendar, Gmail receives an updated invitation, and Google Calendar automatically moves the event to the new time.

I would like to see Proton Calendar do the same thing: automatically add events based on .ics invites in the inbox, and automatically update them based on new .ics invites.

Cross-linking what seems to be the same request to illustrate just how much this is wanted:

As an extension of this, I would like to be able to open an ics attachment in the ProtonMail iOS app and be able to add it to my Apple Calendar as I would in the Apple Mail app.

Agree with others, and suggest PM consolidate similar votes - the entire tally would be much higher. This is a general import/export request for calendar - support common filetypes like .ics, .ical, etc.

I often receive ICS files from a shared Gmail calendar invite email sent to my PM email account.
It would be great to be able to import those invites into my Proton Mail calendar.
I would then be able to manage my personal diary in PM Calendar and see a copy of my gmail calendar invites too.

This would be indeed a great feature, since manually adding entries to calendar might result in errors. Esp. when timezone calculations are involved. Made such mistake myself.

Yes. I would love to press accept in my mail and have the event be added automatically to my calendar. The lack of this makes it hard to jump ship from gmail.

Yes, please this is most needed now.

I agree. I don’t need s full calendar system - just a way to accept or decline iCal invites and maybe forward them to another account so they appear on my calendar. It’s difficult to have an email address on which I cannot accept calendar invites.

I'd like support for calendar files (*.ics) to be added, to allow accepting/declining invites directly from the protonmail application.
