Please, please, please offer a SEARCHABLE calendar. I run a small business, and its absolutely imperative that we can search the calendar for previous meetings with specific clients or where the last meeting took place.
Search for encrypted calendars could be done the same as Tutanota do their search for encrypted emails: An index file is generated LOCALLY to enable search on the user's computer at that particular time. It works well. Similar to how password managers store everything encrypted in the crowd but still allow search on the computer when you are using them.

Pretty, pretty please with a cherry on top, please develop a search function for the calendar.

CALENDAR support and my last Exchange account will be transfered to protonmail. Mine and MANY of my customers', you would like it as much as I would!!

Please offer calendaring and a way to sync contacts to cell phone.

Notes, contacts, and a few binary files storage such as photos & sound-files.
(sharing the quota with e-mail is acceptable)
Managed by tags and list with simple search function.
And calendar.

Calendar is top request.

Document cloud would be great.

Notes would be nice but not essential.

Want to be away from google etc... calendar and reminders are a must

CALENDAR is the most important missing feature.

BTW, the Protonmail VPN May be Free, but you better have a good wireless plan, because when not near WiFi, it uses your Plan. Found that out, when it sucked by data away.

I like many others in this thread, wish to leave Google, totally. Will not move until Protonmail adds this feature.

I don't want to be tied to Gmail or Outlook any more.

Definitely a priority for me too.
As mentioned by many others, this is the feature that enables me to finally insulate myself from the usual service providers...

To leave GMail I need a good calendar alternative to Google Calendar ASAP,

I hope ProtonMail will offer a professional and user friendly calendar really soon and sees this as a huge opportunity to attract many new users!

Calendar is a must. Migrated email over from gmail, but without the calendar functionality it's a little unusable unfortunately.

Key feature (calendar and contact, smartphone compliant), along with send as for professional users (send from within Protonmail using a professional address such as name@compagny.com).

We cannot stress how important this is to us. As a Protonmail and ProtonVPN paid customer, calendar support is of critical interest to us at the enterprise level. All the other options out there, are inadequate from a security perspective. Calendar support simply cannot come soon enough. Let us know when alpha testers are needed.

Overall:

Email - done

Contacts - done

VPN - done

Calendar - Hopefully soon, with compaibility to emclient/outlook and other 3rd party apps.

Basic Notes // we have standard notes, great service. I would like to see some form of collaboration between these two projects where possible.

Cloud drive // closest we have is tresorit and cryptomator for use with mainstream. Perhaps proton could charge progressively.
E.g. 100GB for $5 / 500GB for $10 / 2TB for $18.

All of that in mind, some kind of package deal for the whole shabang with 2TB cloud for about $30 monthly seems a fair deal to me. Branding wise "PROTON-SUITE".

Instead of saving the Full Contact feature for Premium Users, You can allow Free Users to enjoy Full Contact Feature for limited number of Contacts, say, 100 or less or more.

I am also eagerly awaiting a Proton Calendar and perhaps notes too. When you do add calendar to the android app please include a month and decent week view. In the meantime I am using Fruux calendar service which has an android app which allows display sync with the google calendar app and also integrates with em client on windows. Ideally I would rather have a fully fledged Proton client for windows that incorporated the bridge functionality with an emclient front end.

Hi folks,

I am feeling the same frustration as a paid user not having a calendar in the native Android App and not being able to use a third party App like Outlook on Android to use the calendar feature so I can stop using Google services. It kills the purpose of paying for the service as I need calendar reminders to go to my mobile device, not a desktop.

Is there an expected release date for the native calendar or for integration with Outlook on Android?

Thanks,

As most other people here, a calander would be very much appreciated. Will become a paid member the moment it is released. Slowly moving all mail and contact to protonmail. Kids are already over ;)
