I wonder why you have implemented the sharing functionality for calendars outside of protonmail first, although it is obvious to realize this function with already existing accounts within Protonmail.
This would be useful especially for professional accounts as well as lower grades.
kind regards

I would like to have the ability to share my calendars with others in ProtonMail. My wife and I share some calendars. I would like for her to be able to add events to my calendar and the same for myself. I am currently on a Plus plan and would be happy to upgrade her to Plus as well if that is what is needed. Or even combine with to a professional plan.

Thanks

PLEASE

This would be significant features!

A shared calendar, which more than 1 Account can access/edit it. (e.g. Family-Calendar)
Within Proton and Outside Proton.

I have a business account. It would be very nice to be able to give an assistant access to a calendar so they can add events etc. I would also be nice to be able to have a calendar with more than one user so that groups working collaboratively can edit and update etc. I love the idea of my company's data being stored by proton rather than AWS, Microsoft, google etc. Hopefully the functionality for business users will grow.

My wife and I use/manage my calendar. It would be nice if we could have a shared calendar. This feature will be useful to business accounts.

Thank you for considering this.

What about solving this with this idea instead? https://protonmail.uservoice.com/forums/932842-proton-calendar/suggestions/43568148-support-multiple-proton-accounts-in-calendar-mobil That would allow both reading and editing on all sides...

In my family we all use protonmail, and my sons and I work in business together. Being able to share my calendar with other protonmail users would be great.

If we like to get this feature we should unite our votes to one single suggestion. Please change your vote to the next suggestion, which is far more voted:

Function for a shared calendar with proton users. My girlfriend and I each have a Proton account and would like to use a calendar together.

I find it odd how you can currently share your calendar with someone outside of Protonmail, but not someone inside of Protonmail. And also how you can share a web link of your calendar, but not add a web link of someone elses.

Hopefully that's just a half-way point and they'll be fully implementing calendar sharing like you have in Google Calendar soon.

I have a paid account and my wife has a free one. This feature as well as no iphone calendar app are the reasons why she hasn't switched to a paid one. I like what ProtonMail is doing, but the calendar has been in beta for 1.5 years - far too long for something so essential.

I will leave Google Calendar completely once this is available!

Family Calendar

Share event in calendar with another proton user

I'll stay with google calendar until I can share events and views with my spouse and we can coordinate kids events/family outings, etc. It's of very limited use to me if I can't at least invite someone to an event with me - love the idea! Can't wait until this is supported!

Need a working replacement for google calendar to share personal and business calendar with my husband/business partner.

I need features to better share the Calendar. I want the option to share it with other Protonmail users in addition to non-Proton mail users (such as google). I know this will defeat the purpose of privacy, but I want to be the one who decides who gets to see what. This is a critical feature for usability of this service in a business setting.

This is the only reason I haven't switched to protoncalendar yet (still using google calendar) - I need to be able to view other calendars (work calendar, partners calendar etc)

At least shared calendars between PMail users would be a first step. Many people would move their family calendar to Proton Calendar if it was possible.
I know I would.
