Adding your Nextcloud contacts

With a CardDAV address book, your Nextcloud contacts appear in Thunderbird. Thunderbird then fills in their addresses automatically when you write a message. Have your username, your Nextcloud address and an app password to hand (see How your calendar and contacts work with your Nextcloud). You can use the same app password as for your calendar.

Adding your address book

1. In the Spaces Toolbar on the left, click Address Book.
2. Click the arrow next to New Address Book and choose Add CardDAV Address Book. Or use the menu button: Add Account, Address Book and then CardDav Address Book.
3. Under Username, enter your Nextcloud username, and under Location: https://<your-address>/remote.php/dav
4. Click Continue and enter the app password when Thunderbird asks for it.
5. Thunderbird shows your Nextcloud address books under Available address books. Tick the ones you want to add and click Continue.

Replace <your-address> with the address you use to open your Nextcloud in the browser, without https://, for example yourname.webokecloud.nl or cloud.yourcompany.com.

Your contacts are now in the address book. To set how often Thunderbird updates them, right-click the address book, then choose Properties and Synchronise.

Contacts from another program

Do you have contacts in Outlook, Gmail or a local Thunderbird address book? Put them in your Nextcloud first, so you have them everywhere. Export them as a vCard file (.vcf) and import them into the Contacts app in your Nextcloud (see Contacts: creating, groups, importing and exporting and Moving your calendar and contacts from Google, iCloud or Outlook (ics and vCard)).

Tip: Duplicate contacts after moving them? Read Cleaning up duplicate contacts after moving them.

Collected Addresses

Thunderbird also has a local address book called Collected Addresses. It automatically adds the addresses of people you email. This address book is only on your computer. Want one of these contacts on your phone too? Drag it to your Nextcloud address book.
