ICS import fails when VEVENT uses custom TZID ("Customized Time Zone")
Description
Importing an .ics file into Proton Calendar fails when a VEVENT references a custom timezone (e.g. "Customized Time Zone").
This appears to happen when the TZID parameter is used directly in event fields.
Example
Example snippet from the ICS file:
BEGIN:VEVENT
DTSTART;TZID=Customized Time Zone:20260316T083000
DTEND;TZID=Customized Time Zone:20260316T093000
SUMMARY:Example Event
END:VEVENT
Expected behaviorProton Calendar should either:
resolve the custom TZID via the VTIMEZONE definition in the ICS file, or
fall back to the provided UTC offset.
Actual behavior
The import fails because the custom timezone cannot be processed.
Context
ICS files exported from calendar clients such as Outlook often…

Support more than 4 Security Keys
Proton supports only 4 hardware security keys - this is not enough. Especially since using biometrics counts against the 4 key limit. I have three desktop computers which run my Proton accounts, and I have mobile devices which require 1 key. So I can't use the biometrics option without forcing a game of musical chairs with my security keys. I'm forced to continue using and subscribing to my 1Password account rather than Proton Pass until this limit is increased.

Add multiple ways to sort emails.
I originally wanted to ask that we be able to sort our Inbox by tag/label. I did see that idea, but also saw requests to sort by star/no star and sender. So I wanted to combine these into a single improvement - to be able to sort the inbox by any column. Being able to do this, helps improve productivity. I would like to be able to see the emails I consider most important to follow up at the top, for example. It can also be valuable to see all the emails from a particular sender or under a specific…

Allow ProtonMail desktop app to minimize to system tray

Lock desktop app
It would be interesting to be able to lock the Proton Mail Windows application with a security code like the Proton Pass application, both manually and after a certain time, so that you do not have to constantly log out and log in

Add labels to Calendar Events
We have the chance to add tags or labels to emails in Proton Mail. I would like to use the same/new labels in Proton Calendar to be able to search emails and events for a self created label.
This would make dealing with projects much easier.Many thanks

Proton Calendar Countdown Timer
Proton Calendar users should be able to add a countdown timer feature to an event. For example, a user schedules a wedding on the calendar and decides to toggle a button to enable a countdown timer. This feature would especially be useful on mobile devices and could be made into a widget or lock screen display.

Calender events prior to 1970
It is currently only possible to enter calendar events prior to or going back no further than 1970. This makes it difficult to enter birthdates when you wish to track the actual age of the person as well as historical events.
Implement option to enter dates prior to 1970 in Proton Calendar.

increase 3 to 5 in maximum folder hierarchy
Short and concise, I want you to be able to make more subfolders so you can sort better, that is, more than "maximum 3 in the folder hierarchy. My suggestion is 5.

Mail-Checker Addon for Browser
A browser-addon similar to CheckerPlus for Gmail.
I always have my browser open when using my computer, as i listen to mixes on Youtube or live stuff. As i was previously using Gmail i became very used to the Checker Plus, i found it very convenient.
No need for open Tap or Program, just Notification and the ability to read it or respond quickly.4 votes -
Allow additional (family-)users to add new email addresses without being admin.
Having a family subscription and my family members ask me to create new addresses, because they cannot do that themselves. So now I've changed them all to "admin" because I don't want to deal with their email addresses.
But now they can also add new users and delete existing ones - the can even remove me, the primary admin! That really doesn't seem to the right way to do user authorization.
Please add an "Allow address creation" checkbox next to the "Admin" checkbox in the user popup. That would really solve a problem.

Decline a single instance of a recurring event from an external sender
When an external sender invites me to a recurring event series, I would like to be able to decline single instances of that event.
Desired MVP user experience:
1. Person invites me to a recurring event series
2. When I need to decline a single instance of an event, I go to that event on my calendar and set my "Attending?" status for that instance to "No, I won't attend"
3. I am prompted whether I'd like to decline just this event, all future events, or the entire series. I select 'this event'.
4. The single instance of the event…101 votes -
Make it easy to view newsletters that do not have a filter applied
I use the Newsletters feature and have over 300 identified newsletters in my account. It would be helpful if alongside the "Active" and "Unsubcribed" tabs there was a tab that listed newsletters that do not have an existing filter applied.

Dual / Multiple Time Zone View
Please add a simple toggle or an optional second time-zone bar to the calendar view.
Often scheduling events with people in other time zones requires annoying mental math or switching tabs to check conversions and can be easy to make mistakes or get frustrated when the clocks change.
A second time zone on the left of the main calendar can help. Other apps do this with a "sticky" secondary timezone label at the top of the sidebar. For example, you could permanently see both your local time (GMT+1) and your colleague's time (GMT+7) side-by-side.
The instant, at-a-glance clarity removes friction,…

Add the day of the week to the calendar quickview sidebar
Hi, a real simple enhancement that will help loads. In the calendar sidebar in the mail app please add the day of the week to the date. So, at the top is says "Wednesday, 14 Jan 2026" etc. rather than just "14 Jan 2026". It'll help ensure we get appointments, etc in on the right day.

Tags and sub-tags
I would love it if we could have sub-tags. For example, Hawaii would be a tag nested under Travel. Although folders allow subfolders, I think tags are so much more nimble and flexible.

Link to Proton Mail in Proton Calendar sidebar.
Could you add link to Proton Mail in Proton Calendar sidebar or offer it as an option? Currently, only Contacts link appears. I noted that a link to Calendar appears in the Mail sidebar albeit limited.
