Contacts imported from Facebook cannot be exported or synched
If some of the contacts that you tried to export were imported from Facebook, they will not export from Yahoo! Contacts. Contacts imported from Facebook cannot be exported by any method, including:
- Exporting contacts to a .CSV or .VCF file
- Synchronization with a mobile device
- Desktop client sync
- IMAP or CarDAV sync
Contacts imported from Facebook cannot be exported from Yahoo! Contacts by any method; including export to .CSV/.VCF file formats, sync with mobile devices, or sync with a desktop mail/contacts client.
Note: If you had previously set up a CardDAV sync on your mobile device, your Facebook contacts may no longer be accessible in this manner. However, they will still be listed as a contact in your Yahoo! Contacts.
