for protonmail professional users it would be really nice to have the ability to integrate protonmail calendar with booking applications like calendly

This is a mandatory option for my business. I can't contemplate migrating to Proton services until there is a CalDav option - this is as fundamental as IMAP. The web UI is great and all, but I do not operate in a single-vendor environment, nor does anyone I know. Even if CalDav was just available via VPN only, that would work (as a possible compromise.)

Yes I really want CardDAV, CalDAV, and IMAP with a local iOS “bridge” application just like desktop.

Too bad the mobile app doesn’t support any real ProtonMail specific features like mail filters. I still have to keep going to the web site to set up mail filters.

being able to integrate this calendar into my "one calendar" app would be a game changer. I want to fully move over to proton mail but this item is holding me back. I contacted one calendar and they said they need “CalDAV” API and once that's available they will make it happen to integrate!

Being able to use the calendar with Kalendar or KOrganizer in Linux would be nice since it would integrate to my system really well. Any possibility this could be done with the ProtonMail bridge?

Happy about the Android port, would love an additional Linux port

We really need this feature to use the Calendar.

CalDAV support please!
The basic minimum I need is the ability to add Proton Calendar account in iOS

I would really like to be able to sync my calendar and contacts via CalDav and CardDav. Both my phone and tablet support sync via those protocols.

Seems a natural, and the server software is easily available.

I'm using the file storage already, and still trying to get the VPN to work (Linux Mint).

Thanks a lot guys.

To make the calendar far more accessible than the current state, native apps should be available for several platforms, both desktop and especially mobile. Currently, mobile devices cannot use Proton Calendar since there is no app or CalDAV support.

yes please add caldav support!

Definitely need caldav for calendar.

Having an integration with my nextcloud cardav server would be really helpful. People do not want to maintain their contacts in every provider separately.
No one goes away from google because their services are properly integrated (I get all my contacts on my phone when I attach my gmail account etc.).
You should try to leverage other open source software and integrate with them. Maintaining contacts is a crucial point for e-mails...

At least Cardav is important. To be able to sync with the rest of my contacts at fruux or similar is very important. Caldav is icing on the cake.

Can't switch from Fastmail without CalDAV, CardDAV support. I'd have my entire family on ProtonMail in a hurry if this wouldfinally get the attention it deserves.

This is the mail reason I can't switch from gmail.

Cardav and caldav would transform Protonmail - go for it!

I vote for that feature! :)

This feature would be great, nothing fancy, just a calendar with a reminders.

Hi,

the only reason why I cannot migrate completely my domain to ProtonMail, is because of the lack of CALDAV and CARDDAV support (as it was already requested)... I think whenver you decide to release such a feature I will migrate my primary mail very fast :)

Thanks a lot
