Both, Nextcloud and thunderbird devs are already aware of out and trying to find a solution. I hope it will find it’s way already into NC14 and/or next thunderbird/lightning release. ---

There is also this new TBsync plugin that does it much more conveniently (multi calendar and also CardDAV) and doesn’t seem to need this fix (Edit: as pointed out below it does also). Just make sure you use the latest betas as I figured out here: [https://github.com/jobisoft/TbSync/issues/115](https://github.com/jobisoft/TbSync/issues/115) ---

_Edit: Whoops, thought you write “more efficiently” but you actually wrote “more conveniently” 😆. Removed my then obsolete text._ Since it is just a wrapper, it should suffer the same issue: > will add the found calendars to lightning and let lightning handle the sync ---

6th Aug 2020 Having set up an address book in NextCloud I am trying duplicate it into my Thunderbird system so that I can keep the two in sync. So far I have had no success. I am running Thunderbird 68.10.0 (on Ubuntu 20.04) with Provider for CalDAV and CardDAV 1.12 and TbSync 2.12; my NextCloud instance is nextcloudpi at version 18.0.7 (obviously, running on a Raspberry Pi). Following the instruction given at: [https://docs.nextcloud.com/server/12.0/user\_manual/pim/sync\_thunderbird.html](https://docs.nextcloud.com/server/12.0/user_manual/pim/sync_thunderbird.html) and entering the URL given by copying the NextCloud address book link, it is [https://nextcloudpi.local/remote.php/dav/addressbooks/users/Eric/minimalinfo/](https://nextcloudpi.local/remote.php/dav/addressbooks/users/Eric/minimalinfo/) and entering the credentials I use (successfully) to log in to NextCloud clicking on Validate gives the message “Validation failed” (there are three, I think, previous messages which disappear too fast to read but they all end with “X”) This problem is referenced above (and elsewhere) which suggests that the value of a configuration parameter, network.cookie.same-site.enabled, in Thunderbird be changed from true to false. On my version of Thunderbird tat parameter doesn’t exist; adding it to the list and setting it to false as set down here [https://support.mozilla.org/en-US/kb/config-editor](https://support.mozilla.org/en-US/kb/config-editor) does not change the outcome of the creation of the Thunderbird address book – validation still fails. Can anyone point out where I am going wrong. Thanks in advance for any help. Eric ---
