It's sad that this topic is being ignored for so long... I hope, they will pick it up.

Webcal is so usefull...

Has there been any activity on this request?

An integrated email/productivity app that replaces Outlook and supports multiple accounts, including non-Proton email accounts. Integration of other features such as calendar and agenda (in the future maybe even ProtonChat) would streamline productivity.

As some other users have mentioned, it would be great getting calendar support in something (Bridge?) for syncing with Apple Calendar and for syncing contacts in Apple Contacts.
Thunderbird would also be fantastic!

Does Proton's Dev or Sales Engineering team read these posts?

From a customer service perspective not replying to years of comments on an important topic is telling - perhaps their Dev team is so small, they don't have the staff to implement features fast enough. Alternatively, they don't view this as an important feature for the number one email client in the world.

Sigh.

I just subscribed to use Proton Bridge but will cancel as calendar neither contacts cannot be synced. How is it possible this was left out?

This is critical to me. It makes me consider no longer being a paid subscriber.

In looking back at this tread and being a Product Manager one has to ask what Proton's Dev pipeline looks like with respect to greenlighting a project which impacts a majority of email users inside and outside corporations?

Outlook is the default email client in the corporate world yet having the flexibility to sync different calendars would be uber useful - two years and counting later.

Like others have said, I really would like all clients that I use to be looking at the one Proton calendar. I use Outlook on both my desktop and laptop

It would be great to sync calendars across devices while importing to thrid-party apps.

For me this is Critical and Non Negotiable
If this does not happen soon I might have to migrate away from Protonmail unfortunately . Swiss servers are nice but being able to handle my Calendar via Thunderbird on Linux via CalDav should not be a Feature Request in 2023.

I actually pay more monthly for Protonmail than what I was paying for Exchange online which had full calendar integration with Thunderbird via Caldav for half the price.

I need this feature to remain on this platform

As an existing user, this is really the last critical issue for Proton Mail for me. I prefer to have my email and calendar in one place. The calendar especially is very important for users to be able to readily access, otherwise it's not useful. I'm fine with using the proton app for phones, but there is no such app for desktop. Since you already allow syncing with outlook for email, it seems logical to support the calendar feature as well.

I can have polished and smart experience in desktop environments if the Calender Bridge was done. It is just grindy to open browsers just for nothing but checking/modifying your calenders.

A native desktop app would be nice, integration in Thunderbird even nicer.

I am currently using the original Proton Calendar App through the Windows Subsystem for Android on my desktop, Maybe that's an interim solution for you, too?

I've been trying to use it as-is, but without the ability to integrate it like you can many other calendar services, it's really useless.

To me this is the only feature that prevents me from using Proton Calendar. I use Outlook at work and need to switch to Proton calendar on the web regularly for personal use. I need to be able to use one application.

If this feature is available Proton calender syncs with Outlook, I will move to Proton immediately.

It's a *basic* and *more wanted* feature that Thunderbird (and other email clients) can add, edit, delete, modify all type of events in ProtonCalendar via standard calendar protocols (with or without ProtonBridge).

Please, add this feature to ProtonCalendar!

Thanks!.

Surprised this still isn't possible. It's just a simple caldav bridge. EteSync does it flawlessly
