Nextcloud collectives: how can a member with external email address view and edit the notes?

The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • 31.0.6
  • Operating system and version (e.g., Ubuntu 24.04):
    • Yunohost 12.0.17 (Linux)
  • Web server and version (e.g, Apache 2.4.25):
    • nginx, unknown version
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • unknown
  • PHP version (e.g, 8.3):
    • unknown
  • Is this the first time you’ve seen this error? (Yes / No):
    • yes
  • When did this problem seem to first start?
    • on first use: 15.6.2025
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
    • Yunohost webadmin
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • no

Summary of the issue you are facing:

I created a collective with a second user by email address only. I don’t know what to tell the email user howto read and write the collectives pages.

Steps to replicate it (hint: details matter!):

  1. In the contacts app: create a team ‘Kollektiv1’
  2. In the contacts app / Kollektiv1: add a member by email address only , so there are 2 members
  3. In the Collectives app: create a collective ‘Kollektiv1’, Add members: team ‘Kollektiv1’
  4. check members by Manage members: there is myself and the external email address
  5. No email sent to the external address, or what else is to be expected?

Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.
  • If screenshots are useful, feel free to include them.
    • If possible, also include key error output in text form so it can be searched for.
  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
