Is it possible to have a shared calendar that everyone can edit?

artfulrobot · July 29, 2025, 10:52am

Nextcloud Server version Nextcloud Hub 10 (31.0.7)
Calendar 5.3.7 (and earlier)
As a special admin user I created a calendar “shared calendar” and shared it with edit permission with the “staff” group.
As staff member A, I create an event in the shared calendar.
As staff member B, I cannot edit the event.

Is it possible to make the event editable by all it is shared with? I’ve noted that it seems to ascribe ‘organizer’ to the user who created the event, and only they have this permission. Is it possible to make all staff organizers?

EDIT

I’m actually much more confused about who can edit what now. It seems that staff member A has full edit permissions on all the events in the shared calendar, regardless who created them. Other staff member, and also the user account that owns the shared calendar, do not have full edit access to the events on the shared calendar (e.g. we cannot change the date/time and there’s a note about changes will not be propagated..)

So I’m not sure it is the “organizer” at all.

The question remains the same: how can we have events that a team of people can all fully edit?

As usual, this topic is covered in the user guide

@j-ed Thanks for your engagement, but I’m not sure you read either my post or what you linked to?

My post:

I … shared it with edit permission with the “staff” group.

The relevant text on what you linked to: (emphasis mine)

When sharing a calendar with write access, users with whom the calendar is shared will be able to create new events into the calendar as well as edit and delete existing ones.

My post also:

staff member A has full edit permissions on all the events in the shared calendar, regardless who created them[1]. Other staff member, and also the user account that owns the shared calendar, do not have full edit access to the events on the shared calendar (e.g. we cannot change the date/time and there’s a note about changes will not be propagated..)

[1] is how things are described in the one paragraph of detail in the user guide but it only seems to work for one member of the staff group.

This looks a lot like a bug to me, it’s almost as if some members of the staff group have read-only access while others (well, one) has read-write access. Yet there is no difference that I’m aware of between the users - they’re all in the staff group. And my account which owns the calendar and did the sharing-to-group also does not have edit access to events in it.

There’s so many bugs in the calendar (869 at time of writing, or 420 if you want to be strict about which have the “bug” tag) and they don’t get fixed fast (not a criticism, resources, etc.). I could not find anything relevant there, but bug reporting and fixing is challenging - if it can’t be reproduced, it can’t be worked on. I was hoping there was some community experience and workarounds. It’s hard to believe that this is a complete one off.

OK, here’s what I’ve discovered: it’s to do with attendees.

Before any attendees are added, everyone can update a calendar event that is shared with them with “ can edit”; they can change its time/date/title etc. They can also add attendees…
As soon as one attendee is added, the user who made the attendee is automatically added as “organizer”. Once this is done, only that organizer user can make changes

Other side-effects:
- if you are an (invited or otherwise) attendee to an event on a shared calendar, you will now see the event twice in your calendar: once on the shared calendar and a sort of copy in your personal calendar.
- As a non-organizer, viewing the event because it’s been shared with you, you are able to only edit the description on the shared event, even when your share says “can edit” - you can’t..
- As a non-organizer, viewing your personal copy of the event, you can edit the description but this does not change the description on the shared calendar.
- As a non-organizer, your sort-of copy does update with things like date/time changes made to the original event.

So:

Before attendees are added, permissions are controlled by sharing
After one or more attendees are added, permissions are further restricted for everyone except the person who added the first attendee, who becomes the “organizer”.

So directly answering my OP question: no, it is not possible to have a shared calendar that everyone can edit if you need to use “attendees” features.

### Is your feature request related to a problem? Please describe. We are a sma…ll non-profit-organization. We really love the Nextcloud calendar, but there are two small drawbacks with the attendee feature. When creating an appointment in a shared calendar it is not possible to - add yourself (and only yourself) as a attendee and - to only add other people and not be the organizer (or change it afterwards) Why is this useful? - Person A creates an appointment for B and C but will not take part. Person A will be the organizer and cannot change it to A. - Person A creates an appointment in a shared calendar and wants to have it in their personal nextcloud calendar also. Person A can't add themself as an attendee. ### Describe the solution you'd like - You should be able to change the role from any attendee to organizer. - You should be able to add yourself as an attendee in appointments in order to see it in your own personal nextcloud calendar. ### Describe alternatives you've considered The alternative is that these calendar entries are created by a dummy user, which is not great in terms of security or managebility. ### Additional context _No response_

### Steps to reproduce 1. Create a Event, or open a Event. 2. Add someone as A…ttendee 3. Yourself are automatically set as Organizer ### Expected behavior 1. Create a Event, or open a Event. 2. Add someone as Attendee 3. Optionally set an Attendee as Organizer 4. Optionally add yourself as Attendee or Organizer 5. Click on save, to set the roles and send out invitations ### Actual behaviour We are a Team and have a coordinator. This Person coordinates our Team events, but is not the organizer. Mostly this person is not involved in the Events. With Thunderbird it is possible to set other people as Attendee or Organizer without yourself being involved. Nextcloud calendar is always setting oneself as organizer. it is also not possible to set your self as Attendee. One can only add other person, not your self. So if you want to join a Event, that is our Teamcalendar, you can not easily add yourself as Attendee. ### Calendar app version 4.5.2 ### CalDAV-clients used _No response_ ### Browser Firefox 118 ### Client operating system Windows 8 ### Server operating system _No response_ ### Web server None ### Database engine version None ### PHP engine version None ### Nextcloud version 27.1.1 ### Updated from an older installed version or fresh install None ### List of activated apps _No response_ ### Nextcloud configuration _No response_ ### Web server error log _No response_ ### Log file _No response_ ### Browser log _No response_ ### Additional info _No response_

When schedul…ing an event, it is currently not possible as an invited attendee to edit the description or easily suggest or even move the event. Other calendaring solutions allow you to grant invitees the right to change and adjust events. ### Describe the solution you'd like Allow attendees on an event by event basis to edit the event, change the description or title and change time of the event. ### Describe alternatives you've considered using calendars with shared writing rights but that's not really feasible ### Additional context _No response_

### Steps to reproduce 1. As user1 create event and invite user2 2.As user2 dra…g event to different day ### Expected behavior The event should not move to a different day, prevent the event from being dragged or show error dialog. Additionally, RFC does allow for COUNTER offers, so in reality dragging the event to a different time/day, should generate a COUNTER offer that is sent to the organizer. ### Actual behavior Event is moved to another day. ### Calendar app version _No response_ ### CalDAV-clients used _No response_ ### Browser _No response_ ### Client operating system _No response_ ### Server operating system _No response_ ### Web server None ### Database engine version None ### PHP engine version None ### Nextcloud version _No response_ ### Updated from an older installed version or fresh install None ### List of activated apps ```Text ``` ### Nextcloud configuration ```Text ``` ### Web server error log ```Text ``` ### Log file ```Text ``` ### Browser log ```Text ``` ### Additional info _No response_
