Syncing with Thunderbird

Mozilla Thunderbird natively supports CalDAV and CardDAV standards, making it an excellent choice for desktop users on any operating system.

To add your Davnode calendar to Thunderbird:

To add your Davnode address book to Thunderbird:

Troubleshooting

​

”Calendar Not Found”

If Thunderbird cannot automatically discover the calendars using the base URL:

1. Try using the specific path to your user’s calendar. The standard format is often: https://mail.davnode.com/calendars/YOUR_EMAIL_ADDRESS/default/

​

Read-Only Mode

If you can view events but cannot edit them:

1. Right-click the Davnode calendar in the sidebar and select Properties.
2. Ensure Read-only is unchecked.
3. If it remains read-only, check your network connection; Thunderbird often locks calendars if it cannot reach the server to sync changes.
