Synchronization with CarDAV protocol

CardDAV protocol support is not implemented in the current version of the webmail. Use syncML clients to synchronize contacts with mobile client.

You can also export and import contacts from the webmail address book to the mail client.

Go to the Contacts and use the button  to select the appropriate format:
- vCard (macOS)
- CSV (Outlook)
- LDIF (Thunderbird)
