Josh is correct, it isn't really working when there are attendees involved. If you try to edit, it will change the entire series.

You can at least delete single instances, even for events with attendees, but you never get the option for "this event and future events".

Until this is fixed, the support article should be updated to reflect the current state. But this needs to be pushed up the priority list as it's a crucial feature. The fact that this issue only occurs when there are attendees should've been caught before the feature was released.

This does not work when the event has attendees, still, which is abjectly embarrassing.

I got my hopes up based on Peter's comment below and tried, but get the following:

Update recurring event
You will update all the events in this series. An invitation will be sent to the event participants.

There is no such prompt to edit a single occurrence per the support article. This is still, unbelievably, an outstanding deficit in core calendar functionality for Proton Calendar. It should never have come out of beta without this, and it is absolutely unconscionable that it has STILL not been remedied.

This should already be possible according to the support article linked below and based on my own testing just now.

https://proton.me/support/protoncalendar-create-update-and-delete-recurring-events#how-to-edit-or-delete-a-recurring-event

This seems to me pretty "table stakes" - it is incredibly painful, especially when the event is created by someone else (client or business associate) and we cannot change a single occurrence (e.g., declining it) without impacting ALL events - and it looks extremely unprofessional that we can't do something that is taken for granted.

To really be (barely) parity with *all* other calendaring apps, we would need to be able to:

- edit just one instance (location, time, participants); or
- edit "this one and all following"; or
- change response just to one occurrence (attending yes/no)
- delete "all following"

Really basic stuff, honestly.

I agree with others that this is a bit of a dealbreaker at the moment. I've migrated both my personal and business calendars to Proton but have found certain basic missing features like this which make it untenable to use for much longer if this is not solved. (I have a paid Visionary plan)

I agree this is business critical. I look so unprofessional for not being able to adapt appointments with clients.

This is a critical calendaring feature that - without having - will unfortunately make it so I have to move away from Proton if it's not added soon. :-( I couldn't find another issue and whether this includes the ability to respond differently to a series, but it seems like when I can't make one instance of a recurring meeting, I have to decline all of them. The inability to modify a single entry in a calendar series that has other attendees is a dealbreaker.

For the love of all that is right in the world, PLEASE fix this. I have lots of shared family events for 6 people and changing one instance of it isn't possible. So ... very ... painful.

"Update recurring event
Close
Would you like to update all events in this series?
Previous modifications on this series will be lost."

This is annoying when wanting to move an event to another calendar.

Please fix this @Proton-Team! We really need recurring events with attendees to be modifyable! It has caused so much confusion already - it frequently happens that we have to move one instance of a recurring series to another day, but right now, we cannot delete or move a single instance - instead, we have to send out another invite and keep the instance cluttering up our calendars.

This feature is a time-save and avoids creating separate entries with unique updates.

For this reason...I am cancelling my Proton membership.

and excuse my bad typing :)

I completely agree Sean. As a Product Manager, I find it surprising this feature is not available, especially when Proton has as a Business option which I use. Having to delete all recurring events with a client and then send out an new event does not look cood and has caused confusion with my clients.
Come on proton... this one needs to be doen quickly :)

It is possible to edit/delete a single occurrence, but only for non-shared series. For shared series, the problem is still present.

As far as I could test on the web and Android versions of Proton Calendar this is already implemented: I can edit (name, hour, location) a single occurence of a series with or without impacting the rest of the series.
Like in Google Calendar, a prompt appear asking you to choose to apply to single occurence, this event and next ones, or all the series

This is critical! Not being able to cancel a single event of a series make the point of a series unusable

This is actually an interesting requirement and could be implemented by allowing to delete all occurrences of an even within a given time frame. It would also be nice to be able to just mark/select multiple events in the calendar view and then just delete those.

I'd like to delete a recurring event whilst away on a business trip/holiday, however, would like the recurring event to resume after x days away.

Currently, the two ways of doing this is to either 'Delete this event' for each consecutive day for x days (very frustrating when you have multiple recurring events) or to 'Delete this and following events', then re-create the recurring event from the day I want my schedule to resume (again, very long when you have multiple recurring events).

The 'Delete this and following events' feature has been a great help for historical reference purposes so far, so thank you.

This is VERY basic and i was surprised to see that it was not implemented (I just thought I had missed it). Please fix this if you're serious about having a calendar!
