Please! I would LOVE to use Proton Calendar with Thunderbird so I could ditch iCloud! I don't care if it requires the bridge.

I would really like to use the Proton Calendar, but without CalDAV support, there is no way that I would pay for Proton Calendar. And yes, I am paying for other Proton services already.

Bitte Caldav implementieren, ist wichtig für die Kalenderpflege Plattformübergreifend

Leider bin ich immer noch gezwungen, Kalender von Anbietern zu verwenden, welche nur CalDav unterstützen.
Die Unterstützung von CalDav bei Proton würde mir ermöglichen, den Proton-Kalender endlich als Hauptkalender zu nutzen. Solange dies nicht geht, muss ich den Google-Kalender benützen, was ich eigentlich nicht mehr möchte.

Just quoting from Proton's recent blog post:

"Standardization is important for two reasons. The first is that Proton remains committed to the open web. Email is one of the most successful open standards that has ever existed, and a core part of that success is interoperability."

This is a reasonably critical issue for me since I rely heavily on my calendar in daily life. I need to sync the calendar across mobile and desktop. I'm considering whether or not to renew my Protonmail subscription without this feature.

I am already using the Proton Mail Bridge to use my favorite MUA; if CalDav could be integrated into that existing - and perfectly working! - product, that'd be really great.

I agree! I need it to be able to synchronize my proton calendar with the obsidian. That would be great, please make it possible

I love the security of ProtonMail, and the UI for email and the calendar are very user-friendly. However, I have found the lack of CalDav support to bring all my calendars together in one place makes the service unusable. When my subscription is up, I'll begrudgingly move over to iCloud.

Diese CalDav-Funktion wäre für mich essentiell, um endgültig den Proton-Kalender als Hauptkalender zu benutzen.

CalDav for  please.

Agreed - to truly make the switch from Google, having the ability to sync ProtonCalendar (and Contacts) to the (in my case, iOS) ecosystem and native calendar/contact apps is a must.

this feature is really desperately needed

It would be great and super useful if Proton Calendar could be synchronized with Cal.com

Allow Todoist app to integrate with protonmail so that I can transfer data and create templates from them.

I actually signed up not even realizing this wasn't implemented yet. Lucky me, I was about to go for the yearly version but at the last moment decided to give it a month for a trial run. Is there any roadmap for this feature?

One more thing Integration to Postbox using a bridge tool - similar to Protonmail would probably be the best approach.

This is essential feature to enable real adoption of the calendar
