I just found out that there is a system address book that contains exactly the accounts that are read-only and shown as duplicate in the contacts app. The duplicated contacts are also exactly the users of my nextcloud instance.

In the settings dialog of the contacts app I see the system address book and have the option to delete it. But I’m afraid to do it.

Why does this address book exists? Can it just be deleted?

[wwe]

if don’t need this address book you can easily disable it there is no harm to do so

https://docs.nextcloud.com/server/stable/admin_manual/groupware/contacts.html#system-address-book

basically this address book allow the one user to find another users on this instance without adding them into the own contacts list (useful for enterprises)

[sluettmann]

Thanks a lot. Disabling the address book has solved the issue of duplicated, non editable contacts for me.

Just another hint to other users having the same issue. The article mentioned by @wwe does not tell you where to put the value ‘system_addressbook_exposed’. Putting it in the nextcloud config.php did not work for me.

Using the occ command worked, but for users that need to use occ web look for this hint to get your occ web app running again for newer versions of nextcloud.
