The Protonbridge is great for Thunderbird. But with Protonmail creating a full suite it makes sense to make the Bridge work with all of the offerings. Maybe Tasks next??

I'd like this too, on my android phone i use the protoncalendar app but on my desktop/laptop I'd love to use Kalendar with it and integrate it with my os notifications.

I concur. It would be great to use the same bridge for Mail, Calendar, and even contacts since most email clients roll those three into a complete suite. It would make sense to build up the bridge to handle those as well.

Of course, we would need a contacts app (I'm aware of it on ProtonMail) that our phones/tablets can connect to our phones (Android for me) to use that instead of Google or Microsoft.

As long as I can’t combine proton calendar (as private calendar) with my outlook events (work account) I can not use protonmail. I am forced to use for work with Outlook. At the moment I combine my private and outlook in a google calendar. I am not happy with that. So i am looking forward to be able to dig the google calendar for my private life and switch to Proton Calendar.

All for it.
The best User Experience for Outlook users would be the ability to set a calendar within MS Outlook that would seamlessly update via ProtonMail Bridge.

Update to my previous comment.... THERE IS A WAY to have read only access to your protonmail calendar via outlook and overlay with your other calendars....

In your proton mail calendar go to your settings and "share outside proton" full access + copy the url link

Then in outlook right click on other calendars (bottom left below my calendar tick boxes), add calendar, from internet, paste the url

With this approach I was at least able to see my work, uni and personal proton mail calendars all together in outlook

If I receive an invite to proton (or I want to send one), I will still need to login via the browser to accept/send the invite.

It's also worth noting that this calendar in outlook will only refresh every 4 hours.

So, I can't manage all the appts via outlook but at least I can now see them all together + I know when I get an invite, I just need to go into chrome or my android app to press accept.

Hopefully proton releases an update one day, but this is going to have to be good enough for now.

The absence of CalDAV (and CardDAV) in Proton Calendar was almost a deal breaker for me when I was looking to migrate from my previous email host - who offered both.

I may be old fashioned but I still like the desktop email clients and use Thunderbird on PC & Mac systems. Being able to sync appointments and contact across systems including my phone is pretty key for me.

I managed to overcome this limitation by installing the Radicale Cal/CardDAV server on a spare Raspberry Pi but not everyone has that option.

That would be absolutely a game changer. I use protonmail all the time because I can use it on windows outlook. But as long I can’t combine my privat (proton calendar) with my outlook events it doesn’t make sense for me to use it. Who wants to have two different calendars?

An application for all paid users to integrate their ProtonCalendar accounts with popular calendar clients, such as Microsoft Outlook, Mozilla Thunderbird, or Apple Calendar.

I absolutely agree with this. It's already an issue that I can't synchronise my Google Calendar with ProtonCalendar and this is why I cannot use ProtonCalendar at all. There are many plugins that allow for using Google Calendar with Microsoft Outlook as third party applications if there is some reason why direct integration can't be achieved, but for the price that the Visionary subscription costs, and the fact that ProtonMail & ProtonVPN are classing themselves as business-grade products for custom domain mail management, I don't think these features are an unrealistic expectation. I assume that the response will be that it's not done because of "security reasons".

Hi - Love your service. Is there an app that I can put on my phone to sync my work calendar (Outlook) and personal calendar (ProtonCalendar)? Thanks !!

I have a customer who uses Outlook and wants the calendar to sync across his android phone and desktop computer using bridge. I can't find an example where this is currently supported, so would be great if it could work that way.

Being able to manage emails non-web needs contacts and calendar to be complete.

The ProtonMail bridge is quite useful for allowing old-fashioned me to access my encrypted e-mail from my favorite e-mail clients without having to resort to using a web browser. Also useful would be a ProtonCalendar bridge to allow me to use my favorite calendar application with my encrypted calendars.

a feature that allows to synchronize ProtonCalendar with Thunderbird Calendar

It would be amazing to be able to sync with MacOS Calendar (caldav) and MacOS Contacts (carddav) using Proton Bridge!

I would like to be able to access my calendar via Thunderbird (lightning plugin or lightning like plugin). This would emulate google calendar access.

Please make iCal support available via the bridge to synchronize the calendar with Thunderbird or other clients. Thank you.

Could not agree more! I use Evolution exclusively and would love to be able to remove my need for Outlook calendar support.

I completely agree, especially as a paid service. It is really unhelpful for scheduling appointments, integrating with Zoom etc. that we can't integrate the calendar with Zoom and it's making me think of finding another provider because I'm regularly scheduling meetings and I need something to make my work easier / not working across multiple calendars. Thanks!
