I want to use Proton Calendar (as well as contacts) but being forced to use the official apps and not being able to sync them with Thunderbird makes it a complete non-starter. Sticking with iCloud for calendar and contacts until Proton fixes this.

Needs to work with Fedora 40+ BetterBird.

Absolutely important if I want to use my native calendar app that integrates with my devices OS.

Absolute must have, and long overdue.

I would love to see this integrated into Proton Bridge, so I could have both my Proton email and calendar in Thunderbird. If tasks were added as a Proton service, the ability to sync those through Proton bridge would make my workflow complete, and I could completely migrate to Proton services.

Would Love to see CalDav/CardDav support so that I can use my preferred calendar / contacts / tasks apps

Eagerly awaiting news on if this feature will ever be implemented. ICS sharing into Thunderbird is better than nothing, but two way sync is what I need.

Calendar is an acknowledged important part of privacy, closely connected to mail and task lists. via Bridge or another mechanism, this would be much appreciated.

... or allow the Proton solution to integrate calendar, mail and tasks!

I need to be able to see all my calendar events from work and personal in one place. I certainly don't want my work seeing my personal calendar, and I defiently am not prepared to continue with Google or Outlook.

Many thanks for your good work!

Absolute must, i cannot use proton calendar without this as i am required to use outlook calendar for my job. Our species has landed a probe on an asteroid and we can’t have unified email and calendar in 2024?

Would allow me to fully use thunderbird and not half thunderbird half webapp. This is a very important feature

Why the need to reinvent the wheel at every step? Why not let Proton Calendar be an Android Calendar app, so I can use other calendars and sync events to things like my smartwatch? Will we also have to wait at their own clumsy pairing thingy implementation?

More like between important and critical. Heck, I'll even do caldav if that's all you can provide.

If I could buy 10,000 votes to bump this up the dev's priority list, I would! An absolute must for me. I cannot transition away from iCloud Calendar until this is implemented. A corresponding sync with iOS's calendar app is necessary too.

I need a way to share my Proton calendar with my work Outlook. Is this possible? The link provided by the Proton system does not seem to work.

Would like to hear any updates on this as well. I would love Proton Bridge to support syncing with Calendar on Thunderbird. I finally decided to get Proton Plus (considering Proton Family in the future). This is really necessary for me to take this further. I am sure I cannot upgrade my family to Proton or myself to Proton Unlimited without this option.

simply essential

Any update on this?

It's great that we can use Bridge to access email in third-party clients, but since meeting invites get sent by email and you need to be able to open them in an application when you get them, it really doesn't make sense that we can't use Bridge or something like it for calendar too. Of course I get that the underlying technology is different (WebDAV is not IMAP/SMTP) but from a user perspective it makes no sense for email to work and not calendar.

I am using macOS as my personal computer and would like to use the macOS Mail and Calendar App as my main applications.

Although there is now a Proton Mail app with both features available, they are not well integrated into the OS. The Proton Mail app does not work property offline, takes up too much memory and %CPU compared to the macOS apps.

I am also used to the macOS apps and want to stick with them rather than the web-based (neutron?) Proton Mail app.

It would therefore be useful to make the calendar available through the existing Proton Mail Bridge app so that it can be connected with macOS Calendar app, or any other Calendar/Mail application people are using.

Is there any news on this, it has been a while and this feature still does not seem to have been considered?

I'm not happy with using the Proton Mail new macOS Applications as my main Calendar application, as the app has some limitations. For one, the app takes up too much memory and does not seem to work offline.

The macOS Calendar app is much better integrated into the system and has more features and takes up much less memory to function. It would be crucial to be able to connect the calendar to the default macOS calendar or any other client people prefer.
